SYSTEMS AND METHODS FOR MAKING AND USING CONNECTOR ASSEMBLY RETAINERS FOR ELECTRICAL STIMULATION SYSTEMS
First Claim
1. A control module for providing electrical stimulation of patient tissue, the control module comprising:
- a control module housing having an outer surface;
an electronic subassembly disposed in the control module housing;
an electrical interface disposed along the outer surface of the control module housing, the electrical interface coupled to the electronic subassembly;
a header disposed along the outer surface of the control module housing over the electrical interface, wherein the header defines a plurality of ports;
a connector assembly retainer disposed in the header and coupled to the electrical interface, the connector assembly retainer having a first end, a second end, and a longitudinal axis, the connector assembly retainer comprising a plurality of channels each extending along the longitudinal axis of the connector assembly retainer, wherein the connector assembly retainer further comprises a plurality of apertures defined at the second end of the connector assembly retainer such that each of the plurality of apertures is aligned axially with a different one of the plurality of channels, and wherein each of the plurality of ports defined in the header is aligned with a different one of the plurality of apertures defined at the second end of the connector assembly retainer; and
a plurality of connector assemblies each configured and arranged for receiving a lead or lead extension, each of the plurality of connector assemblies disposed in a different one of the plurality of channels of the connector assembly retainer, each of the plurality of connector assemblies comprisinga connector housing defining a port at one end of the connector assembly, the port configured and arranged for receiving a portion of the lead or lead extension,a plurality of spaced-apart connector contacts disposed in the port defined by the connector housing, the plurality of connector contacts each coupled to the electronic subassembly, wherein the plurality of connector contacts are configured and arranged to couple to terminals disposed on the lead or lead extension, andat least one non-conductive spacer disposed between adjacent connector contacts of the plurality of connector contacts.
