Implantabel electrical connector system
First Claim
4. A combination of:
- an implantable female electrical connector adapted for use in one of an implantable pulse generator and an implantable lead extension, the female electrical connector including;
a bore having an opening; and
a plurality of electrical contacts disposed along the bore, the plurality of electrical contacts including a distal most electrical contact closer to the opening of the bore than all of the other electrical contacts of the female connector; and
an implantable electrical lead comprising;
a lead body having a proximal end portion and a distal end portion, the distal end portion forming an inline male connector adapted for connection to the female connector;
a plurality of electrodes on the distal end portion;
a plurality of electrical contacts on the inline male connector, including a distal most electrical contact that is positioned distal of all other contacts of the plurality of electrical contacts of the inline male connector, the distal most electrical contact of the male inline connector having a conductive shoulder substantially facing in the proximal direction for contacting the distal most electrical contact of the female connector and registering the position of all of the plurality of electrical contacts of the inline male connector relative to the distal most electrical contact of the female connector; and
conductive means for electrically communicating between the plurality of electrodes and the plurality of electrical contacts.

Abstract
An implantable electrical connector system, which may be used as part of an electrical lead, a connector block on an implantable pulse generator, or the connector of a lead extension. The distal most electrical contact on the proximal end of the lead (or lead extension) is adapted to provide registration or alignment of all of the electrical contacts of the proximal end of the lead (or lead extension) with electrical contacts of the distal connector of a lead extension or the electrical contacts of a connector block of an implantable pulse generator (IPG). In an exemplary embodiment, the distal most electrical contact on the proximal end portion of the lead may have a flange or shoulder that is adapted to engage the distal electrical contact of the female connection section of a lead extension or connector block. Most preferably, in this exemplary embodiment, the flange or shoulder is an integral part of the distal most electrical contact.

5-1. The combination of claim 4 wherein the plurality of electrical contacts of the inline male connector include, in addition to the distal most electrical contact, a plurality of contact rings each having an outer diameter, the distal most electrical contact of the inline male connector having a first portion having an outer diameter substantially the same as the outer diameter of the contact rings, and a second portion distal of the first portion and extending radially outwardly from the first portion to define the conductive shoulder.
