Synthesis and application of microbubble-forming compounds
The present disclosure is directed to fatty-acid glycerol ester derivative compounds containing a targeting bisphosphonate group. The disclosure further include pharmaceutical or biomedical compositions comprising these compounds, and methods of using these compounds and compositions forming microbubbles. The microbubbles have affinity for metal-containing, especially calcium-containing, bodies and/or biological targets. In certain embodiments, these compositions are useful for providing targeted placement of microbubbles capable of cavitation on application of high frequency energy.
Three-dimensional imaging and modeling of ultrasound image data
The position and orientation of an ultrasound probe is tracked in three dimensions to provide highly-accurate three-dimensional bone surface images that can be used for anatomical assessment and/or procedure guidance. The position and orientation of a therapy applicator can be tracked in three dimensions to provide feedback to align the projected path of the therapy applicator with a desired path for the therapy applicator or to provide feedback to align the potential therapy field of a therapy applicator with a target anatomical site. The three-dimensional bone surface images can be fit to a three-dimensional model of the anatomical site to provide or display additional information to the user to improve the accuracy of the anatomical assessment and/or procedure guidance.
METHOD AND APPARATUS FOR IMPROVEMENT OF MICROCIRCULATION
An apparatus and method for improving microcirculation by suppressing and cancelling the negative effects of electromagnetic radiation from cellular phones and computers connected to wireless networks on microcirculation. The apparatus generates frequencies that are synchronized and in opposed amplitudes to the detected electromagnetic radiation frequencies, thereby suppressing and cancelling the negative effects of the electromagnetic radiation frequencies on microcirculation.
Process for providing protective therapy for biological tissues or fluids
A process that provides protective therapy for biological tissues or fluids includes applying a pulsed energy source to a target tissue or a target fluid having a chronic progressive disease or a risk of having a chronic progressive disease to therapeutically or prophylactically treat the target tissue or target fluid. The pulsed energy source has energy parameters selected so as to raise the target tissue or bodily target fluid temperature up to a predetermined temperature for a short period of time to achieve a therapeutic or prophylactic effect, while the average temperature rise of the target tissue or target fluid over a longer period of time is maintained at or below a predetermined level so as not to permanently damage the target tissue or target fluid.
IMPLANTABLE ULTRASOUND CONDUCTING AND DRUG DELIVERING APPARATUS
An implantable ultrasound conducting and drug delivering apparatus includes a drug-accommodating member and a shell-shaped ultrasound-scattering member mounted on a bottom of the drug-accommodating member. The shell-shaped ultrasound-scattering member thereon has a plurality of scattering through-holes. The drug-accommodating member has at least one linking through-hole formed on the bottom thereof to communicate the bottom of the drug-accommodating member with the shell-shaped ultrasound-scattering member. The shell-shaped ultrasound-scattering member is fitted to be disposed within a physical cavity of a patient. A drug is injected into an accommodating room of the drug-accommodating member. The drug passes through the scattering through-holes and delivers to the physical cavity. An ultrasound propagates to the scattering through-holes, and is scattered by the scattering through-holes to the tissue liquid in the physical cavity, all surfaces of an inner wall of the physical cavity and all tissues neighboring the inner wall of the physical cavity.
SYSTEM AND METHOD FOR OPEN-LOOP ULTRASOUND THERAPY
A method for delivering ultrasound therapy using open-loop controls comprises inserting a distal tip of a therapeutic ultrasound applicator into a patient's urethra, the distal tip including an ultrasound transducer; acquiring ultrasound images of the patient's urethra and prostate with an ultrasound imaging probe; aligning the distal tip of the therapeutic ultrasound applicator with the patient's prostate using the ultrasound images; delivering therapeutic ultrasound energy to the patient's prostate, with the ultrasound transducer, according to a treatment plan, the treatment plan including a predetermined limited angular range for the therapeutic ultrasound energy that avoids the patient's rectum and neurovascular bundles, wherein the therapeutic ultrasound is delivered without temperature feedback data.
Method and apparatus for ultrasonic delivery of drugs and contrast agents
A method, device and system for ultrasonic delivery and attachment of ligand-receptor based drugs and/or drug carriers and/or image enhancing contrast agents utilizing catch and slip bond mechanisms in a targeted part(s) of the human or animal (patient) body or organs or tissue is described and disclosed. The system includes an acoustic power source coupled to an acoustic transducer with the acoustic transducer placed upon a patient's delivery zone. The acoustic transducer transmits an acoustic field to the target drug delivery and/or imaging zone. A detection probe and/or a probe of an imaging system are placed over or within said delivery zone and the probe is coupled to a sensing/imaging system. A control computer that controls power and wave shape of the acoustic signal generated into the acoustic filed by the acoustic power source and receives data from the sensing/imaging system. This system utilizes catch and slip bonds for the delivery of drugs and/or drug carriers and/or image enhancing contrast agents. Placing an acoustic transducer over a delivery zone having ligand-receptor based drugs and/or drug carriers and/or image enhancing contrast agents. The method includes coupling an acoustic power source to said acoustic power source and installing a probe within or over said delivery zone. The probe is coupled to a sensing/imaging system. A control computer is used to control a power and a wave shape of the acoustic field generated by said acoustic transducer. The method uses a catch and slip bonds within said acoustic field to deliver ligand-receptor based drugs and/or drug carriers and/or image enhancing contrast.
LOW INTENSITY ULTRASOUND THERAPY
Provided herein methods for treating a subject suffering from a disease or a disorder associated with hyperproliferating cells, by irradiating the cells with low-frequency ultrasound at an intensity that is either below the cavitational threshold intensity for the ultrasound frequency, or is characterized by a low-frequency mechanical index below 2.5. The methods may further comprise determining an elasticity value of the cells, and adjusting the ultrasound intensity accordingly.
Simulation-based drug treatment planning
Various approaches for computationally generating a protocol for treatment of one or more target BBB regions within a tissue region of interest using a source of focused ultrasound include specifying (i) settings of sonication parameters for applying one or more sequence of sonications to the target BBB region using the source of focused ultrasound and (ii) a characteristic of microbubbles selected to be administered into the target BBB region; electronically simulating treatment in accordance with the protocol at least in part by computationally executing the sequence(s) of sonications and computationally administering the microbubbles having the characteristic; and computationally predicting a tissue disruption effect of the target BBB region resulting from the treatment.
High intensity focused ultrasound systems for treating tissue
High intensity focused ultrasound systems for treating tissue are disclosed herein. A system of treating tissue in a patient in accordance with an embodiment of the present technology can include, for example, an ultrasound source having a focal region and configured to deliver high intensity focused ultrasound energy to a target site in tissue of the patient. The system can further include a controller operably coupled to the ultrasound source. The controller comprises a pulsing protocol for delivering the high intensity focused ultrasound energy with the ultrasound source to the target site. The controller is configured to cause the ultrasound source to pulse high intensity focused ultrasound waves to lyse cells in a volume of the tissue of the subject while preserving an extracellular matrix in the volume of the tissue exposed to the high intensity focused ultrasound waves.
