A connector and lead (or other elongated body) can produce a tactile sensation that indicates alignment between connector contacts of the connector and the terminals on the lead (or other elongated body). For example, a terminal or retention sleeve of the lead (or other elongated body) may include an indented circumferential groove that interacts with a connector contact or retention contact of the connector to produce the tactile sensation. As another example, one or more terminals or spacers may have a larger diameter than adjacent spacers or terminals to interact with a connector contact to produce the tactile sensation.

A leadless pacemaker, a leading component, a trailing component and a delivery device are disclosed. The leading component (10) includes a leading end body (100), a first connection member (101) and a second connection member (102). The trailing component (20) includes a trailing end body (200), a third connection member (203) and a fourth connection member (204).

When the battery of the leadless pacemaker is exhausted, the connection relationship between the leading component (10) and the heart can be kept unchanged, and the trailing component (20) can be conveniently replaced.

A cardiac defibrillation system. The system comprising a housing and an implantable lead. The implantable lead comprising two ends, including a first end connected to the housing and a second end being a free end. The implantable lead also comprising a defibrillation electrode and at least three detection electrodes including a first detection electrode, a second detection electrode, and a third detection electrode.

The third detection electrode and the first detection electrode, or, the third detection electrode and the second detection electrode, or, the housing and one of said detection electrodes, forming a second dipole, where a length of the first dipole is between 5 and 50 millimeters and a length of the second dipole is between 50 and 400 millimeters.

A pacemaker system includes a drive-sense circuit (DSC) operably coupled to a pacemaker lead. The DSC generates a pace signal including electrical impulses based on a reference signal. The DSC provides the pace signal via the pacemaker lead to an electrically responsive portion of a cardiac conductive system of a subject to facilitate cardiac operation of a cardiovascular system of the subject. The DSC senses, via the pacemaker lead, cardiac electrical activity of the cardiovascular system of the subject that is generated in response to the pace signal and electrically coupled into the pacemaker lead and generates a digital signal that is representative of the cardiac electrical activity of the cardiovascular system of the subject that is sensed via the pacemaker lead. The DSC provides digital information to one or more processing modules that includes and/or is coupled to memory and that provide the reference signal to the DSC.

Implantable medical devices have modular lead bores that are constructed from individual lead bore modules. A given modular lead bore utilizes the number of individual lead bore modules necessary for the particular implantable medical device. Each lead bore module has a lead bore passageway and a feedthrough passageway. An electrical contact is present within the lead bore passageway of each lead bore module and the electrical contact is aligned to the lead bore passageway of a lead bore module. Hermetic feedthrough assemblies are also present within the lead bore passageway of each lead bore module. A feedthrough pin passes through a hermetic feedthrough assembly within a feedthrough passageway of each lead bore module. Each feedthrough pin is electrically coupled to a corresponding electrical contact and the medical device circuitry.

A header lock assembly includes a header lock pin and mating lead lock collar that provide a releasable coupling for attaching one or more leads to a device. The header lock assembly is configured to engage the lead to assure closure while not applying undue pressure on the lead. One or more notches in the header lock pin allow the lead to pass the header lock pin unimpeded while the header lock assembly is in an unlocked configuration. Rotation of the header lock pin engages a circumferential groove in the lead lock collar to secure the lead to the header. A slot in the top of the header lock pin provides an interface surface with a lead locking tool for rotating the header lock pin. The slot orientation provides a visual indication of the header lock assembly being in a locked or unlocked configuration.
