Abstract
A connector assembly for a body implantable medical system which interconnects a medical agent providing subsystem with a medical agent delivering subsystem. The connector assembly establishes an interconnected contact force between the medical agent providing and delivering subassemblies that is operator independent. In a preferred embodiment, the connector assembly is formed as an over-center toggle carried by the delivering subassembly. The toggle may be formed of first and second legs, the first leg being a beam spring pivotally secured adjacent one end of the second leg. The other end of the beam spring may be anchored to the medical providing subassembly while that subassembly and the second leg other end are provided with cooperating arcuate bearing surfaces. Relative motion of the bearing surfaces, as by a force applied to the second leg, will cause the toggle to approach and pass through an over-center position to provide a secure mechanical connection between the medical agent providing subsystem and a delivery subsystem which carries the connector assembly.
