An inductive charging antenna for charging the power source of an active implantable medical device (AIMD) is described. The charging antenna is supported on the body fluid side of the feedthrough insulator, on the device side of the insulator or it is embedded inside the insulator. The charging antenna is connected to electronic circuits housed inside the medical device to charge the power source so that the device can deliver electrical stimulation to a patient and receive sensed biological signals from body tissue, among other functionalities. If the charging antenna is supported on the insulator body fluid side, it is made from a biocompatible material such as platinum. However, if the charging antenna is embedded inside the feedthrough insulator or is supported on the device side of the insulator, it can be made from a less expensive material that is not biocompatible, for example, copper.

Feedthrough with an integrated charging antenna for an active implantable medical device

In various examples, a header of an implantable device includes a first header portion and a second header portion at least partially disengageable from the first header portion. In a closed configuration, the first header portion is fully engaged with the second header portion, and in an open configuration, the first header portion is at least partially disengaged from the second header portion. At least one bore within the header is sized and shaped to accommodate a proximal end of a lead. The bore is split substantially longitudinally to form a first bore portion and a second bore portion. With the proximal end of the lead disposed within the bore and a positioning feature interacting with a lead feature, at least one lead contact aligns with at least one header contact to allow the at least one lead contact to electrically couple to the at least one header contact.

Header connection system for implantable medical device

A lead adapter for a patient treatment system comprises a housing having a plurality of inlets, each inlet being segregated from an immediately adjacent inlet by a housing intermediate wall. A plurality of electrical contact assemblies residing in the housing are electrically connected to a respective one of a plurality of electrical contact posts. Each contact post has an exposed terminal portion residing in one of the plurality of inlets. A header is movably secured to the housing to selectively open and close the housing. With the header in an open position, an implantable lead is movable into a longitudinally extending opening in the header. The header is then manipulatable into a closed position to move an electrical contact of the lead into contact with a respective one of the electrical contact assemblies electrically connected to a respective one of the electrical contact posts. That way, the electrical contacts of the implantable lead are in electrical continuity with an exposed terminal portion of a respective one of the electrical contact posts.

Cable-less lead adapter for implantable neurostimulator system

A device that is implantable in body tissue of a human or animal. The device is comprised of a header comprising at least one terminal adapted for removable connection to a lead and an open ended case closed by a plate to form a housing. The housing is comprised of a surrounding edge wall joined to a first side wall and a second side wall opposed to the first side wall. At least a first suture port extends through the edge wall and the second side wall but not the first side wall at an upper edge region of the housing. A second suture port may extend through the surrounding edge wall and the second side wall but not the first side wall in a similar manner. A third suture port may extend through the header. The three suture ports may define a triangular attachment configuration.

Implantable pulse generator with multiple suture ports

A cable assembly for a patient treatment system comprises an electrical cable having a proximal connector configured to connect to an external electrical stimulator device and a distal connector including a distal housing having an open distal end. The distal housing houses a manifold that supports a plurality of spring-loaded electrical contact assemblies aligned in two rows and being electrically connected to a corresponding one of a plurality of electrical contacts in the proximal connector. The housing distal open end is closed by a header that is movable between a closed position resting on the housing open end and an open position spaced there above. The header has a pair of side-by-side longitudinally extending openings. With the header in the open position, a practitioner holds the distal connector in one hand and with the other hand inserts the distal electrical contacts of one or two therapy delivery devices into the longitudinally extending openings. The practitioner then moves the header into the closed position to bring the distal electrical contacts of the therapy delivery devices into firm electrical contact with the spring-loaded electrical contact assemblies housed inside the distal housing.
