Abstract:
Systems and methods for adapting the performance of a wireless communication link with an implantable medical device (IMD) are disclosed. An illustrative method includes initiating a wireless link with the IMD, measuring an initial performance of the wireless link, determining whether the initial performance of the wireless link is adequate, adjusting an operating parameter related to the wireless link in the event the initial performance of the wireless link is inadequate, measuring a performance of the wireless link in response to the adjusted operating parameter, and setting the operating parameter to a prior setting if the measured performance of the wireless link does not improve in response to the adjusted operating parameter.
Abstract:
A system includes a medical device that is implantable. The medical device includes circuitry for processing physiological data, a battery that is rechargeable and that is electrically coupled to the circuitry to provide power to the circuitry, a charge coil arranged to generate current responsive to externally-generated magnetic fields and electrically coupled to the battery to charge the battery, and a magnetic field guide arranged to guide the externally-generated magnetic fields towards the charge coil.
Abstract:
An implantable medical device (IMD) is configured with a pressure sensor. The IMD includes a housing and a diaphragm that is exposed to the environment outside of the housing. The diaphragm is configured to transmit a pressure from the environment outside of the housing to a piezoelectric membrane. In response, the piezoelectric membrane generates a voltage and/or a current, which is representative of a pressure change applied to the housing diaphragm. In some cases, only changes in pressure over time are used, not absolute or gauge pressures.
Abstract:
Improved devices, circuits and methods of operation in implantable stimulus systems. An implantable defibrillator may comprise an H-bridge output circuit having low and high sides, with a current controlling circuit coupled to the high side of the H-bridge output circuit and a current monitoring circuit coupled to the low side of the H-bridge output circuit. Alternate current paths to the output of the H-bridge, or to the H-Bridge itself, are used for delivering different therapies to the patient.
Abstract:
A medical system includes a physiological monitoring system configured to sense a physiological signal and record physiological signal data indicative of the patient's physiological state. The physiological monitoring system including a controller, a storage device, at least one sensor operatively coupled to the controller, and a first communication component. The system includes a mobile device configured to facilitate sensor placement, the mobile device comprising a controller, a display device, and a second communication component configured to facilitate communication between the physiological monitoring system and the mobile device. The controller of the mobile device is configured to provide a graphical user interface (GUI) on the display device, the GUI including information about a proper placement of the at least one sensor, wherein the proper placement is determined based on the physiological signal data.
Abstract:
Various aspects of the present disclosure are directed toward apparatuses, systems, and methods for pacing a HIS bundle of a patient. The apparatuses, systems, and methods may include applying stimulation energy through one or more of a plurality of electrodes to direct a stimulation locus and pace a HIS bundle of a patient.

Abstract:
An implantable leadless pacing device and delivery system may comprise an implantable leadless pacing device and a catheter configured to deliver the implantable leadless packing device to a target location. The implantable device may comprise a power source, circuitry operatively coupled to the power source, a housing at least partially enclosing the circuitry, a first electrode secured relative to and offset from a longitudinal axis of the housing and exposed exterior to the housing, and a fixation mechanism secured relative to the housing. The fixation mechanism may comprise at least one tine configured to move between an elongated delivery configuration and a curved deployed configuration and radially offset from the first electrode. The catheter may comprise a distal holding section defining a cavity configured to receive the implantable leadless pacing device.
Abstract:
