Implantable medical device connector assembly with side-actuated lead body affixation
First Claim
1. A connector assembly for releasably affixing at least two leads to an implantable medical device, each of the leads comprising a lead body, the connector assembly comprising:
- a single side clamp having first longitudinally bisected channels with first surfaces;
a support having a side recess and second longitudinally bisected channels with second surfaces, the side recess to receive the side clamp such that the first surfaces are confrontally disposed with the second surfaces to define longitudinally extending ports, the longitudinally extending ports to receive proximal end portions of the at least two lead bodies; and
a fastener received by the support to urge the side clamp toward the support and to clamp the proximal end portions of the at least two lead bodies between the first surfaces and the second surfaces;
wherein the side clamp has an outer surface that forms an outer surface of the connector assembly when the side recess receives the side clamp.

Abstract
A connector assembly releasably affixes a lead on an implantable medical device. The lead includes a lead body. The connector assembly comprises a support, a side clamp defining with the support confronting surfaces configured to receive a proximal end portion of the lead body. A fastener is adapted to be received by the support for urging the side clamp toward the support and for clamping the proximal end portion of the lead body between the confronting surfaces. The fastener may extend through the side clamp and may be threadedly received by the support. Further, the support may carry a retainer for inhibiting the removal of the fastener from the support. The side clamp and the support may define additional confronting surfaces configured to receive a proximal end portion of an additional lead body, the fastener being adapted to urge the side clamp toward the support to clamp the proximal end portion of the additional confronting surfaces. In addition, the connector assembly of the invention may comprise a top clamp defining with the support confronting surfaces configured to receive the proximal end portion of an additional lead body, and a fastener adapted to be received by the support for urging the top clamp toward the support and for clamping the proximal end portion of the additional lead body between the confronting surfaces defined by the top clamp and the support.
