Tapered implantable lead and connector interface and methods of making and using
First Claim
1. An electrical stimulation system, comprising:
- an electrical stimulation lead connector comprisinga connector housing defining a lead lumen having a width, a lead receiving opening, an end stop, a midpoint between the lead receiving opening and the end stop, and a longitudinal length extending from the lead receiving opening to the end stop, wherein the width of the lead lumen decreases from the lead receiving opening to the midpoint and from the midpoint to the end stop, anda plurality of contacts disposed in the connector housing and longitudinally spaced apart from each other along the longitudinal length of the lead lumen, wherein each of the contacts is configured and arranged to electrically couple to a corresponding terminal of a lead body when an end portion of the lead body is inserted into the lead lumen; and
an electrical stimulation lead comprisinga lead body comprising a longitudinal surface, a distal end portion, a proximal end portion, a proximal tip, and a longitudinal length, wherein the proximal end portion is configured and arranged for insertion into the electrical stimulation lead connector and has a non-uniform width that monotonically increases from the proximal tip,a plurality of terminals disposed along the proximal end portion of the lead body, wherein each of the terminals is configured and arranged to electrically couple to a corresponding one of the contacts of the electrical stimulation lead connector when the proximal end portion of the lead body is inserted into the lead lumen of the connector housing of the electrical stimulation lead connector, anda plurality of electrodes disposed along the distal end portion of the lead body; and
a plurality of conductors electrically coupling the terminals to the electrodes.

Abstract
An electrical stimulation lead connector includes a connector housing and a plurality of contacts. The connector housing defines a lead lumen having a width, a lead receiving opening, an end stop, a midpoint between the lead receiving opening and the end stop, and a longitudinal length extending from the lead receiving opening to the end stop. The width of the lead lumen decreases from the lead receiving opening to the midpoint and from the midpoint to the end stop. The plurality of contacts is disposed in the connector housing and longitudinally spaced apart from each other along the longitudinal length of the lead lumen. Each of the contacts is configured and arranged to electrically couple to a corresponding terminal of a lead body when an end portion of the lead body is inserted into the lead lumen.
