US 2024/0390032 A1 · SPINAL CORD STIMULATION DEVICE IMPLANTATION METHODS AND RELATED SYSTEMS AND DEVICES

Abstract

Methods and devices for implanting spinal cord stimulation devices, including thin-film spinal cord stimulation devices. In some embodiments, the devices include an introduction needle and/or sheath, a stylet, and a pushing device for urging a stimulation device into the epidural space by controlling the proximal end of the device, including, in some cases, deformable thin-film spinal cord stimulation devices. Further implementations include a deployment device for ensuring deployment of the stimulation device in the epidural space. In other embodiments, the devices include sutures attached to a distal portion of the stimulation device, at least one introduction tube, a lead introduction device, and/or a suture introduction device for urging a stimulation device into the epidural space by controlling both the proximal and distal ends of the device, including, in some cases, deformable thin-film spinal cord stimulation devices.

Dependent claims

A thin film spinal cord stimulation system comprising:

(a) a spinal cord stimulation device comprising:
(i) an elongate thin film lead body;
and
(ii) a thin film electrode body disposed at one end of the elongate thin film lead body, the thin film electrode body comprising:
(A) at least two contacts disposed on the electrode body;
and
(B) a pusher receiving structure disposed on a distal portion of the thin film electrode body, the pusher receiving structure having a lumen extending therethrough, the pusher receiving structure having an outer shape comprising a smooth upper surface;
and
(b) an elongate pusher device comprising:
(i) an elongate pusher body, the elongate pusher body having:
(A) a pusher lumen extending through a portion of the elongate pusher body;
and
(B) a distal face disposed at a distal end of the elongate pusher body, the distal face being constructed and arranged to be coupleable with a proximal end of the pusher receiving structure, the elongate pusher body having an outer shape comprising a smooth upper surface.
