An implantable medical device (IMD) is provided and includes electrodes configured to be located in or about a heart. The electrodes include a bipolar electrode combination that define a bipolar sensing vector. The electrodes include a unipolar electrode combination that define a unipolar sensing vector. The IMD includes sensing circuitry configured to define a first sensing channel coupled to the bipolar electrode combination and a second sensing channel coupled to the unipolar electrode combination. The IMD includes memory to store program instructions and one or more processors configured to implement the program instructions to collect cardiac activity (CA) signals over the first and second sensing channels for a series of beats, identify a sensed interval delta (SID) from the CA signals for at least a portion of the series of beats, the SID representing a timing interval between i) a COI in the CA signals collected over the first sensing channel and ii) the same COI in the CA signals collected over the second sensing channel; and designate the series of beats to correspond to be a polymorphic ventricular tachycardia (PVT) or a monomorphic ventricular tachycardia (MVT) based on the SID.

Presented herein are techniques for providing tinnitus relief to recipients via an implantable arrangement. In accordance with embodiments presented herein, an implantable medical device, such as implantable tinnitus therapy device, auditory/hearing prosthesis, etc., comprises one or more implantable sensors configured to be implanted in a recipient. The one or more implantable sensors are configured to detect body noises of the recipient. The implantable medical device is configured to classify/categorize the one or more body noises and set, select, or otherwise determine a tinnitus therapy for the recipient based on the classification of the one or more body noises.

A hearing prosthesis, comprising: a microphone; a sound processor; an external transmitter unit including a coil; an internal receiver unit including a coil; a stimulator unit, wherein the stimulator unit includes a control circuit, a voltage measurement component, a resistor and a signal generator, wherein the measurement circuit is configured to output a signal indicative of the voltage across the resistor; and a stimulating lead assembly array, wherein at least a portion of the hearing prosthesis is configured to apply an electrical signal to tissue inside a cochlea of a recipient, and at least a portion of the hearing prosthesis is configured to sense an electrical property inside of the cochlea that results from the applied electrical signal and the interaction of the applied electrical signal to the tissue.

In some examples, a system may be used for delivering cardiac therapy or cardiac sensing. The system may include an in implantable medical device including a housing configured to be implanted on or within a heart of a patient, a fixation element configured to attach the housing to the heart; and a sensor configured to produce a signal that indicates motion of the implantable medical device. Processing circuitry may be configured to identify one or more impingements between the housing and another structure, such as a tissue of the heart, based on the signal from the sensor and provide an indication of the one or more impingements to a user.

A stimulation circuit generates magnetic stimulation for application to a body organ using a coil arrangement. A DC supply is provided and supplied to a DC/AC inverter that comprises abridge inverter stage comprising plural switch modules connected in a bridge arrangement between input terminals and output terminals for supplying the stimulation signal. A driver circuit supplies pulse width modulation control signals to the switch modules that are selected to control the DC/AC inverter to generate the stimulation signal with pulse width modulation of voltage, thereby providing for a high degree of control of the form of the stimulation.

A method and apparatus to autonomously analyze the surface area and alloy composition ratios of a metallic implant, such as an orthopedic implant, so that an optimal voltage for biofilm disruption can be selected and make treatment easier based at least in part upon the autonomous detection of a hydrogen evolution reaction threshold.

The present invention relates to a male contraception apparatus for obtaining a time-limited sterility of a male mammalian individual. The apparatus comprises a restriction device adapted to restrict the lumen of a vas deferens of the mammalian, and a controller operable to control the restriction device to restrict the lumen of the vas deferens during a controlled period to prevent sperms from reaching the urethra of the mammalian. The apparatus further comprises an implantable constriction device configured to gently constrict at least one portion of a tissue wall of the vas deferens to restrict the lumen of the vas deferens such that the flow of sperms in the vas deferens is restricted, and a stimulation device configured to stimulate the constricted wall portion of the tissue wall.

Techniques regarding neuromodulation are provided. For example, one or more embodiments described herein can comprise a system, which can comprise a memory that can store computer executable components. The system can also comprise a processor, operably coupled to the memory, and that can execute the computer executable components stored in the memory. The computer executable components can include a mapping component that can generate a stimulus map by mapping a stimulus parameter to a response from an entity to application of a neuromodulating stimulus, with the first neuromodulating stimulus being applied to the entity based on the first stimulus parameter, to therapeutically cause or prevent a sensation.
