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:
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:
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:
Medical device systems and methods with multiple communication modes. An example medical device system may include a first medical device and a second medical device communicatively coupled to the first medical device. The first medical device may be configured to communicate information to the second medical device in a first communication mode. The first medical device may further be configured to communicate information to the second medical device in a second communication mode after determining that one or more of the communication pulses captured the heart of the patient.
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:
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:
Systems and methods for treating cardiac arrhythmias are disclosed. In one embodiment, an SICD comprises two or more electrodes, a charge storage device, and a controller operatively coupled to two or more of the electrodes and the charge storage device. In some embodiments, the controller is configured to monitor cardiac activity of the heart of the patient, detect an occurrence of a cardiac arrhythmia based on the cardiac activity, and determine a type of the detected cardiac arrhythmia from two or more types of cardiac arrhythmias. If the determined type of cardiac arrhythmia is one of a first set of cardiac arrhythmia types, the controller sends an instruction for reception by an LCP to initiate the application of ATP therapy by the LCP. If the determined type of cardiac arrhythmia is not one of the first set cardiac arrhythmia types, the controller does not send the instruction.
