Electrical connection system and method for implantable medical devices
First Claim
1. A connector system for establishing an electrical connection between an implanted medical device and a lead, the connector system comprising:
- an array of electrically active pins and complementary electrically conductive receptacles;
wherein one of the array and the complementary receptacles are provided in a recessed area of the implanted medical device and are exposed from the implanted medical device prior to establishing the electrical connection, and the other of the array and the complementary receptacles are encased in a lead housing from which a distal end of the lead extends;
wherein the electrical connection is established upon pressing the pins and the complementary receptacles together;
wherein upon establishing the electrical connection, the lead housing is exposed at an exterior of the implanted medical device; and
a latching device for latching the lead housing to the implanted medical device;
wherein the latching device latches the lead housing to the implanted medical device by drawing the lead housing into the recessed area to establish a latched position of the lead housing; and
wherein the latching device is reversible, and upon removing the latching device and reinserting the latching device in a reversed position, the latching device presses the lead housing out of its latched position.

Abstract
A multiple contact connector interfaces between an implanted medical device and an implanted cable or lead. A connector connects between multiple implanted leads, each of which has multiple independent conductors. The connection system is a planar array of male connector pins on one portion, and a matching array of female connector receptacles on a second portion. Alignment via alignment features and pressing together the portions allows pins to engage with the receptacles providing a secure electrical connection. Sealing features on the connector apparatus seal out external fluids and isolate fluid present in the connector apparatus prior to mating, which electrically isolates each pin and its corresponding receptacle from other pin and receptacle pairs. Latching features retains the relative position of the pins, receptacle, and the positioning of the fluid seals, and is reversible for removal of the connector.

8. A connector system for establishing an electrical connection between an implanted medical device and a lead, the connector system comprising:
-
a connector comprising a body portion that houses a plurality of electrically active contacts and a flange portion extending from the body portion, wherein the lead extends from the connector and is coupled to the electrically active contacts; an implanted medical device comprising a plurality of electrically conductive contacts in a recessed area of the implanted medical device, said electrically conductive contacts exposed from an exterior of the implanted medical device prior to establishing the electrical connection;
wherein the electrically active contacts and the electrically conductive contacts establish the electrical connection upon inserting the body portion into the recessed area; anda seal, wherein upon establishing the electrical connection, the seal is arranged between the connector and the implanted medical device and protects the electrical connection from fluids; and a latching device for latching the connector to the implanted medical device, wherein the latching device latches the connector to the implanted medical device by drawing the body portion into the recessed area to establish a latched position of the connector, and wherein the latching device is reversible, and upon removing the latching device and reinserting the latching device in a reversed position, the latching device presses the body portion out from the recessed area and out of the latched position of the connector. - View Dependent Claims (9, 10, 11, 12, 13)
