Abstract: A surgical method treats infections on a lead positioned at least partially within a patient's body. The surgical method includes uncoupling the lead from a pulse generator. The lead is then coupled to an ultrasound wave generator. Ultrasound waves are propagated from the ultrasound wave generator through the lead. Systems are disclosed.

Abstract: An implantable medical device performs a method that includes detecting a cardiac event interval that is greater than a P-wave oversensing threshold interval. In response to detecting the cardiac event interval greater than the P-wave oversensing threshold interval, the device determines the amplitude of the sensed cardiac signal and withholds restarting a pacing interval in response to the amplitude satisfying P-wave oversensing criteria. A pacing pulse may be generated in response to the pacing interval expiring without sensing an intrinsic cardiac electrical event that is not detected as a P-wave oversensing event.

Abstract: Various embodiments of a ventricular assist system and a method of using such system are disclosed. The system includes a pump adapted to be connected to a heart of a patient, an outflow cannula including a first end adapted to be connected to an outlet of the pump and a second end adapted to be connected to an artery of the patient, and an electrode disposed on an outer surface of the outflow cannula and adapted to be disposed adjacent to an exterior wall of the heart. The system further includes a controller electrically connected to the pump and the electrode, where the controller is adapted to provide a pacing signal to the electrode.

Abstract: Novel tools and techniques are provided for implementing intelligent assistance (“IA”) or extended intelligence (“EI”) ecosystem to placement procedures for cardiac implantable electronic device (“CIED”). In various embodiments, a computing system might analyze received one or more first layer input data (i.e., room content-based data) and received one or more second layer input data (i.e., patient and/or tool-based data), and might generate one or more recommendations for guiding a medical professional in performing a CIED placement procedure in a heart of the patient, based at least in part on the analysis, the generated one or more recommendations comprising 3D or 4D mapped guides toward, in, and around the heart of the patient. The computing system might then generate one or more XR images, based at least in part on the generated one or more recommendations, and might present the generated one or more XR images using a UX device.
