First Claim
Patent Images
1. A medical electrical lead comprising a connector terminal, the connector terminal adapted to mate with a medical device and comprising:
- an electrical contact element;
a seal zone element positioned adjacent the contact element;
an elongate conductor extending from the proximal end of the lead into the connector where the conductor couples with the contact element; and
a relatively rigid strut member completely formed from at least one electrically insulative material and including an outer surface and an inner surface, the inner surface forming a longitudinal lumen extending through the strut,a seal zone supporting protrusion extending from the outer surface of the strut member and upon which the seal zone element is mounted;
a contact supporting protrusion extending from the outer surface of the strut member, the contact supporting protrusion being longitudinally spaced apart from the seal zone supporting protrusion and upon which the contact element is mounted;
an adhesive backfill positioned beneath the seal zone element and the strut outer surface; and
a longitudinal channel formed within the strut member facilitating application of the adhesive backfill from an end of the strut member.

57. A medical electrical lead, comprising a connector coupled to a proximal end of the lead, the connector adapted to mate with a medical device and comprising:
-
an electrical contact element including an outer surface and an edge recessed from the outer surface and extending from an end of the contact element; an elongate conductor extending from the proximal end of the lead into the connector where the conductor couples with the contact element; a seal zone element positioned adjacent the contact element and including an inner surface overlapping the recessed edge of the contact element and an outer surface adapted to sealingly engage with an internal sealing ring of the medical device;
the outer surface free of protrusions exceeding a height of approximately 0.003 inch and approximately flush with the outer surface of the contact element;a relatively rigid strut member supporting the electrical contact element and the seal zone element; and an insulative end cap mounted on an end of the strut, wherein one of the contact element and the seal zone element is held between the end can and the other of the contact element and the seal zone element. - View Dependent Claims (58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71)
