The plurality of conductive contacts includes a plurality of electrodes and a plurality of terminals. At least one of the conductive contacts is a first conductive contact that includes at least one adhesive aperture defined between an inner surface and an outer surface of the at least one conductive contact. A plurality of conductors each electrically couple at least one of the electrodes to at least one of the terminals. Each first conductive contact has a conductor associated with, and electrically coupled to that first conductive contact. The adhesive is disposed in proximity to the at least one adhesive aperture of at least one first conductive contact to adhesively couple that first conductive contact to the at least one associated conductor.

A lead connection system includes a connector housing. A plurality of lead retainers disposed in the connector housing are configured and arranged to removably attach to a proximal end of one of a received plurality of leads. The plurality of lead retainers include at least one of a slidable drawer and at least one pivotable hinged panel. A plurality of connector contacts are configured and arranged for making electrical contact with one or more of the terminals of one or more of the plurality of received leads. A single connector cable has a distal end that is electrically coupled to the plurality of connector contacts and a proximal end that is configured and arranged for insertion into a trial stimulator. A cable connector is electrically coupled, via the connector contacts, to at least one terminal of each of the received plurality of leads.
Abstract:
Specific low density polyethylene articles that exhibit improved physical characteristics and other benefits over previously made articles produced by less efficient means are provided. Such articles require the presence of saturated or unsaturated bicyclic dicarboxylate nucleating agents that impart increased crystallization temperatures, permit lower manufacturing cycle times, and, most importantly, cause a drastic reduction in warpage at quick cooling times during production. These resultant articles thus can be produced more efficiently with reliable low-warpage characteristics.
Abstract:
A method of manufacturing a device for brain stimulation includes forming a lead body having a distal end section and coupling at least one pre-electrode to the distal end section of the lead body. The pre-electrode defines a divider with a plurality of partitioning arms, and has a plurality of fixing lumens. A portion of the pre-electrode aligned with the portioning arms is removed to divide the pre-electrode into a plurality of segmented electrodes. Each of the plurality of segmented electrodes defines at least one of the plurality of fixing lumens at least partially disposed through the segmented electrode. A material is introduced through the at least one fixing lumen to couple the plurality of segmented electrodes to the lead body.

Abstract:
A lead anchor comprises a housing, and a plunger. The housing comprises a rigid body and a flexible covering disposed over at least a portion of the rigid body. The housing defines a first opening and a second opening configured and arranged to receive a lead. The housing further defines a transverse lumen. The rigid body comprises one or more projecting locking ridges extending into the transverse lumen. A plunger comprising one or more locking detents disposed thereon is configured and arranged for insertion into the transverse lumen and engaging a lead and locking with the housing by engagement of at least one of the one or more locking ridges of the housing with at least one of the one or more locking detents of the plunger. At least one suture element is formed by the flexible covering for receiving a suture to suture the lead anchor to patient tissue.

A lead assembly includes a lead with a distal end and a proximal end. The lead includes a plurality of electrodes disposed at the distal end and a plurality of terminals disposed at the proximal end. The lead also defines at least one central lumen and a plurality of outer lumens. The central and outer lumens extend from the proximal end to the distal end such that the plurality of outer lumens extend laterally from the at least one central lumen. The lead further includes a plurality of conductive wires. Each conductive wire couples at least one of the plurality of electrodes electrically to at least one of the plurality of terminals. At least two conductive wires are disposed in each of the plurality of outer lumens.
Abstract:
A connector assembly includes a lead or a lead extension, a connector, and a retention assembly disposed in the connector. The connector includes a connector housing defining a port at a distal end of the connector, and a plurality of connector contacts disposed in the connector housing.
