Embodiments of the present disclosure include a medical device. The medical device may include an elongate member, a first control member and a second control member each coupled to a distal end of the elongate member, an actuator coupled to the first control member and the second control member and configured to selectively move the first control member and the second control member to steer the elongate member, and a holding mechanism deflecting a path of the first control member from the actuator to the distal end of the elongate member and a path of the second control member from the actuator to the distal end of the elongate member. The holding mechanism may be configured to apply tension on one of the first control member and the second control member as the other is moved to steer the elongate member.

Steerable medical device having a control member holding mechanism

An insertion tool for a paddle lead includes an insertion tool body having a receiving end portion; a stylet channel extending along the insertion tool body; a stylet disposed in the stylet channel; and an actuator assembly disposed along the handling end portion of the insertion tool body and coupled to the stylet. The actuator assembly controls transitioning of the stylet between a first position and a second position. In some instances, the stylet can be a wire stylet that is inserted into a lumen in the paddle body of the paddle lead. In some instances, the stylet of the insertion tool pushes lead bodies of the paddle lead out of the insertion tool to release the paddle lead. In some instances, the insertion tool includes a paddle envelope to hold the paddle lead.

Insertion tool for implanting a paddle lead and methods and systems utilizing the tool

A stimulation lead includes an electrode carrier disposed along a distal portion of a lead body. The electrode carrier defines multiple segmented-electrode-receiving apertures extending between an outer surface and a central lumen. Each of the segmented-electrode-receiving apertures includes a ledge disposed around a perimeter of that segmented-electrode-receiving aperture and inset from the outer surface of the electrode carrier. The stimulation lead also includes multiple segmented electrodes, with each of the segmented electrode disposed in a different one of the segmented-electrode-receiving apertures with an outer stimulation surface exposed through the segmented-electrode-receiving aperture and an inner surface abutting the ledge disposed around the perimeter of that segmented-electrode-receiving aperture. Conductive wires extend along the lead body and couple the segmented electrodes to terminals.

Leads with electrode carriers for segmented electrodes and methods of making and using

A medical device including an elongate member having a proximal end, a distal end, and at least one lumen extending therebetween. The medical device may also include at least one proximal control member extending within the elongate member from the proximal end to the distal end of the elongate member, a coupling mechanism disposed adjacent a distal portion of the elongate member, and an end-effector removably coupled to the distal end of the elongate member, wherein the end-effector includes at least one distal control member extending proximally therefrom, and wherein the coupling mechanism is configured to removably couple the at least one distal control member to the at least one proximal control member.

Medical device with quick-release mechanism

An electrical stimulation lead includes at least one lead body and at least one thin, elongate anchoring element. The lead body defines at least one anchoring lumen extending longitudinally along at least a portion of the lead body and at least one open slot in the lead body where each anchoring lumen is open at one of the at least one open slot. For each anchoring element, the first end of the anchoring element is disposed in one of the at least one anchoring lumen and the second end of the anchoring element is configured and arranged preferentially to extend out of the open slot associated with the anchoring lumen and away from the lead body in a deployed configuration unless the second end is constrained in a constrained configuration adjacent or within the lead body.

Electrical stimulation leads and systems with elongate anchoring elements

A lead extension for an electrical stimulation system includes a lead-extension body, terminals, and a connector. The connector includes a contact housing and a gasket housing. Multiple connector contacts are disposed in the contact housing and are coupled to the terminals. A retention member is disposed along one end of the contact housing and is receivable by a retention socket defined in the gasket housing. A deformable gasket is disposed in the retention socket. A lumen extends through the connector and is suitable for receiving an electrical stimulation lead. The received lead is retained in the lumen by using the retention member to compress the gasket along a longitudinal length of the connector. The longitudinal compression of the gasket causes a corresponding radial expansion of the gasket, which retains the electrical stimulation lead within the lumen.
