Abstract: A connector that includes contact assemblies and non-conductive stack spacers separating the contact assemblies from each other, the contact assemblies and the stack spacers defining a connector lumen configured to receive a portion of an electrical stimulation lead. The contact assemblies and stack spacers are brazed together forming a sealed connector stack that resists passage of fluid between the contact assemblies and stack spacers. Alternatively or additionally, the stack spacers are made of a non-conductive ceramic, crystalline, or glass material.

Abstract: An electrical stimulation lead includes a lead body having a distal end portion and a proximal end portion; electrodes disposed along the distal end portion; terminals disposed along the proximal end portion; and conductors extending within the lead body and electrically coupling the electrodes to the terminals; wherein at least one of the electrodes or terminals includes a capacitive contact having a first outer cylinder, an inner cylinder at least partially disposed within the first outer cylinder, and a first non-conductive dielectric deposited between the inner cylinder and the first outer cylinder. The capacitive contacts can also be used as contacts in a connector of a lead extension or a control module.

Abstract: A connector assembly includes an elongated connector housing having a first end, a second end, and a length, the connector housing defining a port at the second end of the connector housing for receiving a proximal end of a lead or lead extension; a lead lumen that extends from the port into the connector housing; connector contacts axially spaced-apart and disposed along the lead lumen for coupling to terminals along a proximal end of a lead or lead extension; and non-conductive spacers disposed between adjacent connector contacts. Each of the spacers includes a first radial sidewall, a second radial sidewall, and an intermediate region extending between, and connecting, the first and second radial sidewalls. The first and second radial sidewalls and intermediate region define boundaries of an open circumferential space opposite the lead lumen with respect to the intermediate region.

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.

Abstract: A connector assembly includes an elongated connector housing and defines a port at one end of the connector housing for receiving a proximal end of a lead or lead extension; a lumen that extends from the port along at least a portion of the length of the connector housing; connector contacts axially spaced-apart and disposed along the lumen for coupling to a proximal end of a lead or lead extension; and non-conductive spacers disposed between adjacent connector contacts. Each of the spacers includes an outer tubular extension, an inner tubular extension, and a connection region coupling the outer tubular extension to the inner tubular extension. The inner tubular extension has a free end and the inner tubular extension is configured and arranged to form a seal against the proximal end of the lead or lead extension when inserted into the lumen.
