    Abstract

    Described is a device for preventing thrombosis formation on surfaces of a blood contact device. The device may first non-invasively scan the blood contact device and determines the highest risk thrombosis points. The device then, preferably starting with the highest risk location, delivers a succession of harmonic vibration signals or electromagnetic signals non-invasively so as to prevent clot formation at each stagnation high risk point of the blood contact device (e.g., harmonic resonance). This resonant vibration calibration tuning information is stored in an associated microprocessor. The signals are then delivered, based upon the stored information, in a loop from the signal generator, usually on a belt outside the patient, to each stagnation point in sequence from highest risk of thrombosis to lowest; again and again repeated. By delivering such energy to the blood contact device stagnation points, initiation of thrombosis formation is prevented, thus preventing the accumulation of thrombosis to a dangerous risk level for stroke, pulmonary embolism, and/or other blood clot induced ailments. This device may be used to prevent and/or treat blood clot, plaque, and/or calcification formation on any blood contact surfaces including living surfaces such as heart valves.

    DETAILED DESCRIPTION

    [0046] In certain embodiments, described is a vibrational device for preventing thrombosis formation on blood contact surfaces. Blood clots, calcification and plaque form on blood contact surfaces within the human body and within blood contact medical devices. These unwanted build ups can cause strokes, embolisms, and heart attacks causing loss of life, brain or body functions and quality of life. The devices described herein prevent the formation of blood clot formation, calcification, and/or plaque formation on blood contact surfaces.

    [0047] The vibrational device 10 (FIGS. 1 and 2) typically includes a sensor, a harmonic vibration signal generator or sensor, and a harmonic vibration microprocessor analyzer optionally mounted or affixed, e.g., by a belt 11 to a subject. In some embodiments, it lacks (or disables or ignores) the sensor, and predetermined signals may then be used to achieve resonance if desired. The harmonic vibration signal generator can be any device (e.g., a speaker) able to create and deliver and/or target acoustic or other vibrational energy signals to a desired location (e.g., focused or directed sound akin to a focalized tuning fork at stagnation points associated with the blood contact device). The harmonic vibration microprocessor analyzer can be any microprocessor with associated memory able to store information that can be retrieved on demand and analyzed with appropriate software. The harmonic vibration microprocessor analyzer is preferably programmed to recognize resonance at the blood contact surface. The device typically includes an associated resonant calibration switch for triggering the device to scan, e.g., a blood contact device 12 to determine the highest risk stagnation points, and then to deliver a sequence of signals 14 at each stagnation point until resonant harmonic vibration is reached. The device 10 communications with, e.g., a subject or health care provider's cellular telephone 16, e.g., by BLUE TOOTH technology, instructing the subject, e.g., where to best position the belt for optimization of results at particular times Afterward, the operator may, e.g., then actuate a run thrombosis prevention loop program.

    [0048] The harmonic vibration device preferably utilizes a custom vibration signal for each surface stagnation point prone to blood clot formation, calcification, and/or plaque aggregation and stops the initial particles from adhering; thus stopping the progressive build up before it starts. Previous devices failed to tune to the correct frequency for the specific treatment surface. The instant device customs tunes (at the correct frequency) to reach harmonic vibration of the particular stagnation prone surface, thus preventing the beginning of buildup and blood clot formation, calcification, and/or plaque aggregation.

    [0049] Such a device preferably customizes the vibrational signal to reach harmonic frequency for the specific treatment surface and cycles through a variety of signals when needed for multi-surface applications.

    [0050] The harmonic vibrational device preferably first non-invasively scans a blood contact device and determines the highest risk thrombosis points in a system or blood contact device. See, e.g., the incorporated Tosi et al. Vibrational spectroscopy as a supporting technique in clinical diagnosis and prognosis of atherosclerotic carotid plaques: a review, Anal Quant Cytopathol Histpathol. 2012 August; 34(4):214-32 and Nakazawa et al. Vibration assessment for thrombus formation in the centrifugal pump Artif Organs. 1997 April; 21(4):318-22.

    [0051] The harmonic vibrational device then, starting with the highest risk location, delivers a succession of harmonic vibration signals non-invasively until harmonic resonance is reached for each stagnation high risk point of the blood contact device. This resonant vibration calibration tuning information is stored in a microprocessor preferably associated with the harmonic vibrational device. The signals may then be delivered, based upon the stored information, in a loop from the signal generator (e.g., on a belt outside the patient), to each identified stagnation point, preferably in sequence from highest risk of thrombosis to lowest risk, which is again and again repeated.

    [0052] By delivering harmonic resonant vibrational energy to the blood contact device stagnation points, the initiation of thrombosis formation is prevented, thus preventing the accumulation of thrombosis to a dangerous risk level for stroke, pulmonary embolism, and/or other blood clot induced ailments. The vibrational device may be used to prevent blood clot(s), plaque(s), and/or calcification(s) on any blood contact surface, including living surfaces such as heart valves.

    [0053] The device preferably customs tunesat the correct frequencyto reach harmonic vibration of the particular stagnation prone surface thus preventing the beginning of buildup.

    [0054] In manufacturing and testing, the device is first preferably mounted in a manner similar to the way it will be put to use with a subject. A vibrator, which preferably comprises a variable speed eccentric motor, is mounted on (or otherwise associated with) the device and coupled to a control electronics package. A vibration transducer is likewise mounted on device and provides an electrical output to the electronics package as a function of amplitude of device vibration. The electronics package includes a knob or other suitable control means for selectively varying frequency of vibration applied to the device by a motor, a gauge or other suitable readout for indicating frequency of vibration to an operator, and an output coupled to a recorder for providing on, e.g., an X-Y plotter having the frequency response characteristics of device recorded thereon.

    [0055] In a particular aspect, a method of analyzing a device comprises applying mechanical cyclic vibration energy to a the device over a test frequency range; monitoring damping effects of energy flowing into the device as a function of frequency and identifying a plurality of orders of harmonic vibration absorption peaks, each consisting of a plurality of vibration absorption resonant peaks; and then applying mechanical cyclic vibration energy to the device for an extended period of time at fixed frequency corresponding to a sub-harmonic frequency of one of the harmonic peaks.

    [0056] In such a method, monitoring damping effects of energy flowing into the device as a function of frequency and identifying a plurality of orders of harmonic vibration absorption peaks may comprise mounting a vibration transducer on the device to provide an electrical output signal as a function of vibration amplitude, and damping response of the transducer to mechanical vibration such that the output varies as a function of harmonic groups of vibration resonant peaks.

    [0057] The method may also include, before applying mechanical cyclic vibration energy, selecting the fixed frequency as a function of composition of the device. In such a method, this may comprise selecting a part of a particular order of harmonics from among the plurality of orders as a function of composition of the device, and identifying a sub-harmonic frequency associated with the part of a particular order of harmonics and corresponding to a vibration amplitude equal to approximately one-third of maximum vibration amplitude of the part of a particular order.

    [0058] In another aspect, a method of analyzing a part of a device includes applying mechanical cyclic vibration energy to the part of a device over a test frequency range, monitoring damping effects of energy flowing into the part of a device as a function of frequency by mounting a vibration transducer on the part of a device to provide an electrical output signal as a function of vibration amplitude and damping response of the transducer to mechanical vibrations such that the output varies as a function of harmonic groups of vibration resonant peaks, identifying at least one peak of harmonic vibration absorption consisting of a plurality of vibration absorption resonant peaks, and then applying mechanical cyclic vibration energy to the part of a device for an extended period of time at fixed frequency corresponding to a sub-harmonic frequency of the at least one harmonic peak.

    [0059] In such a method, the method can further include monitoring the damping effects while applying energy, identifying any changes in harmonic frequency of the one peak, and reselecting the one peak as a function of the changes identified.

    [0060] U.S. Pat. No. 7,824,358 B2 to Cotter et al., Nov. 2, 2010 (the contents of which are incorporated by this reference in its entirety), discloses a heart assist device connection system comprising an inflow connector in fluid-tight communication with an inflow section of a heart assist device. The connector is configured to be releasably connected to an inlet extension inserted into a patient's ventricle. The connector has one or more recesses configured to match a protrusion on the inlet extension. The system also comprises an outflow connector in fluid communication with an outflow section of the heart assist device. The outflow connector is configured to be releasably connected to a conduit attached-to the patient's vasculature.

    [0061] The natural vibration (harmonic) frequencies of a surface may be determined (or estimated) based upon its length, Young's modulus for the material present, mass density, and structure of the surface. There are natural frequencies for both longitudinal and compressional waves, which generally have different values. A standard mathematical technique exists for this, which may be implemented with, e.g., a software package.

    [0062] The natural vibration frequencies will depend somewhat on, e.g., whether the device containing the surface is secured or free. If secured, the device needs to be done so firmly to a very strong, heavy object or the resonances will be lossy. If unsecured, one can set the device on springs or hang it from, e.g., a bungee cord.

    [0063] There are a variety of techniques to apply vibration to the device. One can hit it, e.g., utilizing a piezoelectric hammer that measures how much force was applied. One can push on it with a probe attached to a piezoelectric or electromagnetic pusher. If the surface is magnetic or can have a magnet attached, one can use an electromagnet. One can also bombard it with sound (e.g., via a speaker system). If nothing else is suitable, one might put the device near a high voltage and push it electrostatically.

    [0064] To sense the vibration, there are many contacting and non-contacting sensors, including magnetic, capacitive/electrostatic and optical. For larger objects, an accelerometer may be used.

    [0065] In order to find frequencies in the output, one may utilize a spectrum analyzer, which generates waveforms suitable for driving the forcer, takes the Fourier transform of both output and input, and divides to produce a transfer function. Peaks corresponding to the resonances will result.

    [0066] Potential applications for the device include applying vibratory energy to heart implants, left ventricle assist devices (which are place closer to the heart), in place heart valves, coronary arteries and coronary stents within coronary arteries that wrap around the heart, in the legs (see, e.g., FIG. 1, but also including having multiple devices up on down the legs separated about 12 inches apart from the upper thigh to the ankles), hair growth stimulation, acceleration of tooth growth, treatment of erectile dysfunction recovery, and/or brain function recovery.

    [0067] For extracorporeal devices, vibration may be administered, e.g., by a commercially available vibrator (e.g., available from Hitachi) tuned to the particular harmonic frequency. Alternatively, a variable speed eccentric motor may be mounted to the device.

    [0068] As used herein, electromagnetic radiation includes radio waves, microwaves, infrared, light, visible light, ultraviolet, X-rays, and gamma rays. Generators and/or emitters of each electromagnetic radiation is known to those of ordinary skill in the art.

    [0069] Also described herein is an electromagnetic radiation generating device for preventing thrombosis formation on blood contact surfaces. Blood clots, calcification and plaque form on blood contact surfaces within the human body and within blood contact medical devices. These unwanted build ups can cause strokes, embolisms and heart attacks causing loss of life, brain or body functions and quality of life. The electromagnetic surface treatment device prevents the formation of blood clot formation, calcification, and/or plaque formation on blood contact surfaces, including the starting point of buildup. While not intending to be bound by theory, it is believed that the applied electromagnetic radiation changes surface ions on the blood contact surface to be repulsive to the materials forming, e.g., the clot.

    [0070] The device 30 (FIGS. 3 and 4) typically includes a sensor, an electromagnetic radiation generator or emitter, and a microprocessor analyzer optionally mounted or affixed, e.g., by a belt 11 to a subject. In some embodiments, it lacks (or disables or ignores) the sensor, and predetermined signals may then be used for application to the blood contact surface as desired. The electromagnetic radiation generator can be any device able to create and deliver and/or target electromagnetic radiation. The microprocessor analyzer can be any microprocessor with associated memory able to store information that can be retrieved on demand. The device includes an associated resonant calibration switch for triggering the device to scan, e.g., a blood contact device 32 to determine the highest risk stagnation points, and then to deliver a sequence of signals 34 at each stagnation point to prevent clot formation or calcification. The device 30 communications with, e.g., a subject or health care provider's cellular telephone 36, e.g., by BLUE TOOTH technology, instructing the subject, e.g., where to best position the belt for optimization of results at particular times Afterward, the operator may, e.g., then actuate a run thrombosis prevention loop program.

    [0071] A preferred electromagnetic surface treatment device utilizes a custom electromagnetic signal for each surface stagnation point prone to blood clot formation, calcification, and/or plaque aggregation and stops the initial particles from adhering; thus stopping the progressive build up before it starts. Previous devices failed to tune to the correct frequency for the specific treatment surface. The instant device customs tunes to deter the beginning of buildup and blood clot formation, calcification, and/or plaque aggregation.

    [0072] The device may then customize the electromagnetic signal for the specific treatment surface and cycles through a variety of signals when needed for multi-surface applications.

    [0073] The electromagnetic surface treatment device preferably first non-invasively scans a blood contact device and determines the highest risk thrombosis points in a system or blood contact device

    [0074] The electromagnetic surface treatment device then, starting with the highest risk location, delivers a succession of electromagnetic signals non-invasively for each stagnation high risk point of the blood contact device. This electromagnetic radiation tuning information is stored in a microprocessor preferably associated with the electromagnetic surface treatment device. The signals may then be delivered, based upon the stored information, in a loop from the signal generator (e.g., on a belt outside the patient), to each identified stagnation point, preferably in sequence from highest risk of thrombosis to lowest risk, which is again and again repeated.

    [0075] By delivering electromagnetic energy to the blood contact device stagnation points, the initiation of thrombosis formation is prevented, thus preventing the accumulation of thrombosis to a dangerous risk level for stroke, pulmonary embolism, and/or other blood clot induced ailments. The device may be used to prevent blood clot(s), plaque(s), and/or calcification(s) on any blood contact surface, including living surfaces such as heart valves.

    [0076] In manufacturing and testing, the device is first preferably mounted in a manner similar to the way it will be put to use with a subject.

    [0077] There are a variety of techniques to apply an electromagnetic signal to the surface.

    [0078] Potential applications for the device include applying electromagnetic radiation to heart implants, left ventricle assist devices (which are place closer to the heart), in place heart valves, and/or coronary arteries and coronary stents within coronary arteries that wrap around the heart, in the legs (see, e.g., FIG. 3, but also including having multiple devices up on down the legs separated about 12 inches apart from the upper thigh to the ankles).

    [0079] The invention is further described with the aid of the following illustrative Examples.

    Example IWireless Powered and Miniature Stent-Based Circulatory Assist Pumps

    [0080] A wireless powered and stent based circulatory assist pump is made utilizing various technologies. For example, an Intravascular Miniature Stent Pump can be made as described in U.S. Pat. No. 7,998,190 (Aug. 16, 2011), the contents of which are incorporated herein by this reference. A Hydroimpedance Pump can be made as described in U.S. Pat. No. 7,163,385 (Jan. 16, 2007), the contents of which are incorporated herein by this reference. A Resonant Multilayer Impedance Pump can be made as described in U.S. Pat. No. 8,092,365 (Jan. 10, 2012), the contents of which are incorporated herein by this reference.

Using these described technologies, a wireless powered circulatory assist pump is designed to be placed within the aorta of a patient. The product is designed to reduce the risk of hemolysis, thrombosis, mechanical breakdown, and infection associated with previously developed circulatory assist devices as well as easing placement.

    [0082] This technology may be applied to the treatment of heart failure, reducing risk in high risk PCI, cardiogenic shock recovery, kidney protection, and limb salvage. One of the uses of the device is to eliminate excess fluid buildup from a patient suffering from heart failure. The wireless powered circulatory assist pump may have the option for both continuous and pulsatile flow.

    [0083] To this technology is applied a wireless harmonic vibration technology, which reduces risk associated with thrombosis (blood clotting), often a problem associated with previous chronic long term use circulatory assist devices.

    [0084] In certain embodiments, resonant frequency may be determined by placing the object next to a speaker (ex vivo) and also placing a microphone attached to an oscilloscope next to the object. The speaker plays a tone at a given volume, and thenwithout changing the volumethe pitch (or frequency) is slowly changed. Observing the oscilloscope identifies certain frequencies that the amplitude of the wave, which is proportional to the volume of the sound being picked up by the microphone, is greater than at surrounding frequencies. These are the resonant frequencies of the object, and are detectable as the sound energy absorbed by the object is re-emitted more efficiently at these pitches. The resulting data may then be entered into the device for application and use after the blood contact device has been implanted into the subject.

No. 3,352,303 to Delaney describes a method for blood clot lysis by the direct application to the clot of sonic or supersonic energy vibrations. [0128] U.S. Pat. No. 4,058,075, which issued to Piper on Nov. 15, 1977, discloses a marine life growth inhibitor device. The device is used for inhibiting marine life on the outer surface of submerged object such as boat. The device includes a controller connected to a source of electrical power and a plurality of speakers electrically connected to the controller and attached at predetermined locations on the interior of the boat's hull, whereby vibrations may be transmitted through the hull. [0129] U.S. Pat. No. 5,143,011 to Rabbette (Sep. 1, 1992) discloses a method and apparatus for inhibiting barnacle growth on boats. The system for inhibiting growth of barnacles and other marine life on the hull of a boat includes a plurality of transducers or vibrators mounted on the hull and alternately energized at a frequency of 25 Hertz through a power source preferably the boat battery, and a control system [0130] U.S. Pat. No. 5,386,397 to Urroz (Jan. 31, 1995) describes method and apparatus for keeping a body surface, which is in contact with water, free of fouling. A sound wave is generated for keeping a surface free of scale, fouling and dirt by the adherence of organisms such as marine life, the surface being part of the body that is in contact with water. [0131] U.S. Pat. No. 5,532,980 to Zarate, et al. (Jul. 2, 1996), discloses a vibrational anti-fouling system that produces vibrations in an underwater structure for the purpose of inhibiting the attachment of aquatic life forms to the structure. The system utilizes loudspeaker-like resonators which operate underwater and produce acoustic vibrations continually having a duty cycle of 3.65 seconds which includes a current drive period of 0.4 seconds. [0132] WO01/58750 provides an ultrasonic anti-fouling device which teaches of devices that are hung outside a hull and arranged so that the vibrations are directed to run parallel to a surface of the hull. [0133] U.S. Pat. No. 5,713,848 to Dubrul et al., Feb. 3, 1998, describes a catheter suitable for introduction into a tubular tissue for dissolving blockages in such tissue. It is useful for removing thrombi within blood vessels. Dissolution of vascular thrombi is facilitated by advancing a catheter through an occluded vessel, the catheter causing a vibrating, stirring action in and around the thrombus usually in combination with the dispensing of a thrombolytic agent (e.g., urokinase) into the thrombus. Catheters allow both low frequency (1-1000 Hz) vibratory motion and delivery of biological agents to a blockage. [0134] U.S. Pat. No. 6,285,629 provides an ultrasonic vibration device; a voltage is applied to a submerged marine structure to exert thereon vibrational and electric energies, thereby effecting deterioration prevention of the structure. An ultrasonic vibration unit comprises an ultrasonic vibrator made from a piezoelectric ceramic plate with an electrode on each side thereof; power supply wires connected to the respective electrodes; a support member for fixedly supporting the ultrasonic vibrator and transmitting the ultrasonic vibration to the structure; and a resin coat for protecting the ultrasonic vibrator against seawater. The ultrasonic vibration unit is used for preventing deterioration of the submerged marine structure. [0135] U.S. Pat. No. 7,517,328 to Hoffmann (Apr. 14, 2009) describes a low frequency vibration assisted blood perfusion emergency system. [0136] US Patent Application Publication 2009/0314193 to Groves et al. (Dec. 24, 2009) describes an ultra-sonic device that inhibits growth of waterborne flora and fauna on, e.g., boats and the like.
