摘要:
A connector assembly for detachably coupling a proximal end of a lead and an implantable medical device. The connector assembly includes a deflectable connector clip having a first arm, a second arm and a top portion extending between the first arm and the second arm. The first arm and the second arm detachably position the proximal end of the lead within the implantable medical device. A housing portion has a first deflection portion that deflects the connector clip from a first position corresponding to a first distance between the first arm and the second arm, to a second position corresponding to a second distance between the first arm and the second arm. Subsequent advancement of the lead through the first and second arms further deflects the connector clip from the second position to a third position, which transfers all of the spring force of the connector clip to the lead.

Devices, systems, and techniques for managing heat generated in coils for wireless energy transmission are disclosed. Inductive coupling between two coils may be used to recharge the power source of an implantable medical device. A phase change material may be thermally coupled to a flexible coil to absorb heat generated during the inductive coupling and reduce temperature increases of the flexible coil. The flexible coil may be configured to at least one of transmit energy to or receive energy from a second coil, and the phase change material may be configured to deform with the flexible coil and absorb heat from the flexible coil. The phase change material may be contained within thermally conductive tubes or channels configured in shapes that promote flexibility of the flexible coil.

A battery having an electrode assembly located in a housing that efficiently utilizes the space available in many implantable medical devices is disclosed. The battery housing provides a cover and a shallow case a preferably planar, major bottom portion, an open top to receive the cover opposing the bottom portion, and a plurality of sides being radiused at intersections with each other and with the bottom to allow for the close abutting of other components located within the implantable device while also providing for efficient location of the battery within an arcuate edge of the device. The cover and the shallow case being substantially hermetically sealed by a laser weld technique and an insulator member disposed within the case to provide a barrier to incident laser radiation so that during welding radiation does not impinge upon radiation sensitive component(s) disposed within the case.

This application discusses, among other things, a header assembly for coupling a medical electrical lead to a medical stimulating device including a header having a capture mechanism within a bore of a lead retention device. In an example, when the lead retention device is retracted from the bore, the capture mechanism prevents the device from falling out. In another example, the header assembly has a vent disposed within the bore of the lead retention device that permits unrestricted flow of air when the lead retention device is retracted from an engagement surface.

This application discusses, among other things, an implantable medical device including a setscrew that enables lead tip visibility as an indicator of full lead insertion without requiring a grommet. In an example, the implantable medical device header is provided with a lead bore and a setscrew bore with the setscrew bore having a longitudinal axis that extends in a transverse direction to, and in communication with, the lead bore. In one example, the setscrew bore intersects with the lead bore at a location that is offset from the central longitudinal axis of the lead bore.

Structures and methods relating to electrodes for incorporation into a feedthrough with a profile adapted for subcutaneous sensing of physiologic and cardiac signals. Electrode assemblies are adapted for integration with feedthroughs and provide reliable insulation from the implantable medical device housing. Various structures and manufacturing processes are implemented to provide a large sensing surface with a low profile. The subcutaneous sensing electrode assembly can provide a leadless sensing system and further enhances installation and follow-up procedures.

This application discusses, among other things, an implantable medical device including a setscrew that enables lead tip visibility as an indicator of full lead insertion without requiring a grommet. An example setscrew has a metal core with an insulative coating disposed over the core to electrically isolate it from body fluids and surrounding tissue. In another example, the setscrew incorporates a sealing capability by including a sealing member that is coupled to the setscrew.
