CONNECTOR CARTRIDGE STACK FOR ELECTRICAL TRANSMISSION
First Claim
1. A free standing in-line connector comprising:
- a stack having two axial ends, said stack comprising;
at least two conductive ring elements each having an internal diameter;
a plurality of seal elements each comprising an internal diameter; and
wherein a conductive ring element is positioned in between two adjacent seal elements;
at least two canted coil springs each in contact with one of the at least two conductive ring elements; and
wherein an encapsulation layer surrounds the stack and overlaps at least one of the two axial ends of the stack to maintain the stack axially compressed outside of an implantable medical header.

Abstract
Connector assemblies for use with implantable medical devices having easy to assemble contacts are disclosed. The connector assemblies are generally formed by coupling a plurality of ring contacts, sealing rings, and spring contact elements together with at least one holding ring to form a connector having a common bore for receiving a medical lead cable. Contact grooves or spring chambers for positioning the spring contact elements are formed in part by assembling multiple components together. A further aspect is a provision for encasing each connector assembly or stack inside a thermoset layer or a thermoplastic layer before over-molding the same to a sealed housing.
