Method and device for detecting a neural response in a neural measurement
A method for processing a neural measurement obtained in the presence of artifact, in order to detect whether a neural response is present in the neural measurement. A neural measurement is obtained from one or more sense electrodes. The neural measurement is correlated against a filter template, the filter template comprising at least three half cycles of an alternating waveform, amplitude modulated by a window. From an output of the correlating, it is determined whether a neural response is present in the neural measurement.
Biocompatible electrode structure and method for manufacturing the same, and device and method for manufacturing the same
There is provided a biocompatible electrode structure which is capable of being connected to an electronic circuit, and in which a conductive nanomaterial is dispersed into a polymeric medium in which a density of the conductive nanomaterial on an opposite side of a connection surface to the electronic circuit, in the polymeric medium is lower than that on the side of the connection surface to the electronic circuit.
METHODS OF ASSESSING CONTACT BETWEEN AN ELECTRODE AND TISSUE USING COMPLEX IMPEDANCE MEASUREMENTS
The present disclosure is directed to a system and method for measuring impedance across a plurality of electrodes and assessing proximity or contact between electrodes of a medical device and patient tissue. In one embodiment, contact is assessed individual electrodes and cardiac tissue using bipolar electrode complex impedance measurements. Initially, baseline impedance values are established for each of the individual electrodes based on the responses of the electrodes to the applied drive signals. After establishing the baseline impedance values a series of subsequent impedance values are measured for each electrode. For each electrode, each subsequent impedance value may be compared to a previous baseline impedance value for that electrode. If a subsequent impedance value is less than the baseline impedance value for a given electrode, the baseline impedance value may be reset to the subsequent impedance value. Such systems and method are particularly applicable to medical devices having numerous electrodes.
Physical assessment parameter measuring device
A physical assessment parameter sensing device includes a layer attachable to a patient, a sensing unit operable to detect a physical assessment parameter of the patient, and an antenna connected to the circuit and operable to receive and transmit a radio frequency signal. The antenna is movably disposed within the sensing device. In certain examples, the sensing device includes an enclosure within which the antenna is movably received.
Systemic biomarker sampling apparatus
An oral procedural apparatus includes a main body, a bite block attached to the main body, and a sampling return line at least partially disposed within the main body. The sampling return line is configured to connect to a systemic biomarker sampling device that samples exhaled breath of a patient.
MEDICAL DEVICE FOR DETERMINING AN EXTREMUM OF A PERIODIC PHYSIOLOGIC SIGNAL
A medical device for determining an extremum of a periodic physiologic signal, comprising a computing unit, a memory unit, and a detecting unit configured to detect a periodic physiologic signal of a human or animal. In operation, the device performs the following steps: detecting a periodic physiologic signal with the detecting unit; dividing the periodic physiologic signal into a plurality of equally long intervals having an interval length, wherein the interval length is chosen such that it is longer than an expected maximum periodic time of the periodic physiologic signal; determining an absolute maximum and/or an absolute minimum of the periodic physiologic signal within each interval; calculating an average value of the determined absolute maxima and/or an average value of the determined absolute minima; storing or outputting the calculated average values of the determined absolute maxima and/or the determined absolute minima as extremum of the periodic physiologic signal.
Integrated circuit medical devices and method
A method of making a universal implantable integrated circuit medical device platform having integral and monolithic circuit traces. The platform allows for implanting into a mammalian body single and multi-functional interface devices for sensing, monitoring stimulating and/or modulating physiological conditions within the body. Microelectronic circuitry may be integrated onto the platform or may be joined as modular components to the platform.
NEURAL INTERFACE FABRICATION
Methods for fabricating implantable cuff electrodes for contacting or at least partially surrounding internal body tissue such as, e.g., nerves, smooth muscles, striated muscles, arteries, veins, ligamental tissues, connective tissues, cartilage tissues, bones, or other similar body tissues, structures and organs are disclosed. An example method includes preparing a substrate including an implantable cuff electrode shape, applying a mold material to the substrate, curing the mold material to form a mold, releasing the mold from the substrate, inserting at least one conductor into the mold that penetrates through the channel of the mold, pressing a formable material into the channel of the mold to form a body of an implantable cuff electrode about the at least one conductor, curing the body of the implantable cuff electrode, and releasing the body of the implantable cuff electrode from the mold.
System, method and apparatus for sensor insertion
Embodiments provide a sensor insertion tool (SIT) that provides a motive force for insertion of an analyte sensor into/through skin. A SIT may be releasably locked to one or more components of a sensor insertion system, such that components of the sensor insertion system remain securely coupled during sensor insertion. A SIT may include a release member that unlocks or uncouples the SIT and the other components after sensor insertion. In various embodiments, a SIT may be a component of a sensor insertion system configured for assembly by an end user, a health care professional, and/or a caretaker prior to sensor insertion, and may act in cooperation with other sensor insertion system components. Additional components and methods of assembly and use are also provided herein.
BONE FIXATION METHOD
A method of monitoring a bone fracture in an individual. The method comprises the steps of: measuring a first parameter indicative of the load on said bone fracture; measuring a second parameter indicative of the activity level of said individual; obtaining a plurality of values for said first and second parameters; correlating said values to determine a measure of bone fracture condition; monitoring a change in said correlation over time; and determining a measure of the change in bone fracture condition over time. A bone fixation system implements this method of monitoring a bone fracture in an individual. The method and system provide a more accurate and reliable measure of bone fracture condition and of the progression of healing of the bone fracture.
