Lead connector for a body implantable stimulator
First Claim
1. In a body implantable stimulator of the type having furcated lead means and a signal generator assembly including signal generator means and connector means for interconnecting said signal generator means and the lead means furculae, at least the lead means furculae being wrapped around said signal generator assembly on implantation, the improvement wherein said connector means comprises jack means for receiving said lead means furculae, said jack means comprising means for compensating for non-uniform spacing of said jack means from said signal generator means to facilitate the conformance of said furculae to the configuration of said signal generator assembly on wrapping of said furculae around said signal generator assembly.

Abstract
An improved connector for interconnecting a furcated lead and signal generator to form a body implantable stimulator. The connector is secured to the signal generator to form a signal generator assembly. Jacks are provided in the connector to receive the lead furculae while facilitating conformance of furculae to the configuration of the signal generator assembly on wrapping of the furculae around the signal generator assembly. In a preferred embodiment, the jacks accept the furculae at different distances from the signal generator to allow a thinner signal generator assembly and at different depths to compensate for the difference in distance of the jacks from the signal generator.
