Abstract: In some examples, an implantable medical device (IMD) that includes a pulse generator comprising a housing, electrodes, and circuitry configured to deliver cardiac pacing via the electrodes. The IMD may further include a lead including at least one of the electrodes, an elongate body, a fixation helix, and a connector segment. A width of the helix transverse to a longitudinal axis of the lead is greatest at a distal end of the helix. A proximal end of the elongate body may be connected to a distal end of the pulse generator, and the helix may be attached to a distal end of the elongate body. The pulse generator may include a first connector tab. A distal end of the connector segment may be configured to receive the proximal end of the elongate body and a proximal end of the connector segment may include at least one second connector member configured to engage the first connector tab.

Abstract: 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.
