Abstract:
An implantable medical device (IMD) may include a housing having a proximal end and a distal end and a set of one or more electrodes connected to but spaced apart from the housing. The IMD may further include a controller disposed within the housing, wherein the controller is configured to sense cardiac electrical signals, and deliver electrical stimulation pulses via the first set of one or more electrodes. In some embodiments, a first portion of the housing is configured to be disposed at least partly within a coronary sinus of a patient's heart and a second portion of the housing is configured to be disposed at least partly within a right atrium of the patient's heart.
Abstract:
A system includes a medical device lead including a connector at a proximal end of the lead, a conductor electrically connected to the connector at a proximal end of the conductor, and at least one electrode coupled to a distal end of the conductor. The system further includes a device securable to the proximal end of the lead including an inductive element. The device includes a port configured to receive the connector and position the inductive element around at least a portion of the connector.
Abstract:
Systems and methods for managing communication strategies between implanted medical devices. Methods include temporal optimization relative to one or more identified conditions in the body. A selected characteristic, such as a signal representative or linked to a biological function, is assessed to determine its likely impact on communication capabilities, and one or more communication strategies may be developed to optimize intra-body communication.

Abstract:
Various embodiments concern a suture sleeve for securing an implantable lead with a suture. The suture sleeve can comprise a tubular body having a proximal end portion, a distal end portion, an exterior surface, and a lumen, the lumen sized to receive the implantable lead. The suture sleeve can further comprise a suture receiving area along the tubular body, the suture receiving area within a channel that extends around a circumference of the tubular body. An exterior surface of the suture receiving area can comprise a tear resistant feature. The tear resistant feature can be configured to resist initiation of a tear in the exterior surface from the suture. The lumen can comprise an inner surface configured to frictionally engage the implantable lead.
Abstract:
A subcutaneous implantable cardioverter-defibrillator (S-ICD) comprising shocking electrodes configured to reduce the defibrillation threshold. The S-ICD may include a canister housing a source of electrical energy, a capacitor, and operational circuitry that senses heart rhythms and an electrode and lead assembly. The electrode and lead assembly may comprise a lead, at least one sensing electrode, and at least one shocking electrode. The at least one shocking electrode may extend over a length in the range of 50 to 110 millimeters and a width in the range of 1 to 40 millimeters.
Abstract:
Methods and devices for testing and configuring implantable medical device systems. A first medical device and a second medical device communicate with one another using test signals configured to provide data related to the quality of the communication signal to facilitate optimization of the communication approach. Some methods may be performed during surgery to implant one of the medical devices to ensure adequate communication availability.
Abstract:
Catheter and implantable leadless pacing devices, systems, and methods utilizing catheters and implantable leadless pacing devices are disclosed. An example catheter system may include a holding structure extending distally from a tubular member. An implantable device, such as a leadless pacing device, may be located within a cavity of the holding structure. The holding structure may include one or more electrical ports adjacent the proximal end of the holding structure and adjacent or proximal of the proximal end of the implantable device. The electrical ports may provide a conductive pathway extending through the distal structure to allow electrical signals to pass through the distal structure to and/or from the implantable device.
