Slotted sleeve neurostimulation device
First Claim
1. An electrical stimulation lead for stimulating a target nerve, the electrical stimulation lead comprising:
- an elongated sleeve having a first portion and a second portion, the first portion hingedly coupled to the second portion, the elongated sleeve having an inner surface that continually extends from the first portion to the second portion and an outer surface that continually extends from the first portion to the second portion, the inner surface defining a nerve channel to receive the target nerve, the elongated sleeve further having a longitudinal slit extending from the outer surface to the nerve channel, the longitudinal slit extending along an entire length of the elongated sleeve, wherein a section of the first portion hingedly moves relative to a section of the second portion to receive the target nerve into the nerve channel, wherein the elongated sleeve includes tapered end portions;
a plurality of electrodes disposed on the inner surface of the elongated sleeve;
a lead body;
a plurality of conductors extending along the lead body; and
a ribbon cable extending from the elongated sleeve and attached to the lead body to electrically couple the conductors extending along the lead body to the plurality of electrodes, wherein the ribbon cable includes a bellowed portion for strain relief.

Abstract
An electrical stimulation lead for a target nerve includes a sleeve having an inner surface and an outer surface, the inner surface defines a nerve channel. A longitudinal slit extends from the outer surface to the nerve channel and along an entire length of the sleeve. A width of the slit retains the target nerve within the nerve channel when the sleeve is closed and releases the target nerve when open. A plurality of electrodes are disposed on the inner surface of the sleeve. A flexible transition element electrically couples a lead body to the plurality of electrodes. Upper and lower sections of the sleeve rotates about a common hinge line (e.g., like a clam shell) located directly opposite the longitudinal slit. The material along the common hinge line remains “elastic” when the sleeve is moved from closed to open, and vice-versa.
