Abstract
A neurostimulation lead includes a lead body having a proximal portion and a distal portion and a first conductor extending through the lead body. An electrode cuff can be secured relative to the distal portion of the lead body. The electrode cuff includes a cuff body, a first tendril extending from a first region of the cuff body, a second tendril extending from a second region of the cuff body and a first electrode disposed on the cuff body and electrically connected to the first conductor.

A neurostimulation lead comprising:
- a lead body having a proximal portion and a distal portion;
- a first conductor extending through the lead body;
- and
- an electrode cuff secured relative to the distal portion of the lead body, the electrode cuff including:
- a cuff body having a first region and a second region;
- a first tendril extending from the first region of the cuff body;
- a second tendril extending from the second region of the cuff body;
- and
- a first electrode disposed on the cuff body and electrically connected to the first conductor.
A neurostimulation lead comprising:
- a lead body having a proximal portion and a distal portion;
- a first conductor extending through the lead body;
- a second conductor extending through the lead body;
- and
- a first cuff secured relative to the distal portion of the lead body, the first cuff including:
- a first cuff body;
- a first tendril extending from the first cuff body, the first tendril biased to a curved configuration in which the first tendril curves in a first direction;
- a second tendril extending from the first cuff body, the second tendril biased to a curved configuration in which the second tendril curves in a second direction opposite the first direction;
- a first electrode disposed on the first cuff body and electrically connected to the first conductor;
- and
- a second cuff secured relative to the distal portion of the lead body, the second cuff including:
- a second cuff body;
- a third tendril extending from the second cuff body, the third tendril biased to a curved configuration in which the third tendril curves in a third direction;
- a fourth tendril extending from the second cuff body, the fourth tendril biased to a curved configuration in which the fourth tendril curves in a fourth direction opposite the third direction;
- and
- a second electrode disposed on the second cuff body and electrically connected to the second conductor.
A method of securing a neurostimulation cuff to a surgically exposed nerve, the method comprising steps of:
- disposing the neurostimulation cuff proximate the nerve, the neurostimulation cuff including a cuff body and first and second tendrils extending from the cuff body;
- positioning the neurostimulation cuff in position on the nerve;
- securing the first tendril in position by wrapping the first tendril around the nerve in a rotational direction;
- and
- securing the second tendril in position by wrapping the second tendril around the nerve in the same rotational direction.
