Abstract
Nerve cuff deployment apparatuses and methods of using them to deliver a nerve cuff electrode to a target nerve trunk.
Claims27
A method of minimally-invasively attaching a nerve cuff electrode to a patient's nerve root, the method comprising:
- minimally invasively inserting a cannula into the patient's body to a nerve root region;
- inserting a nerve cuff deployment tool into the cannula, wherein the nerve cuff electrode is attached at a distal end of an elongated body of the nerve cuff deployment tool, further wherein the elongated body of the nerve cuff deployment tool has a column strength sufficient to resist buckling at compressive forces of at least 10 N;
- advancing the nerve cuff deployment tool distally through the cannula into the nerve root region;
- and
- disengaging the nerve cuff from the nerve cuff deployment tool by separating two halves of a nerve cuff capsule at the distal end of the nerve cuff deployment tool and coupling the nerve cuff electrode to the patient's nerve root.

(canceled)
A nerve cuff deployment apparatus for minimally invasively attaching a nerve cuff electrode to a patient's nerve root, the apparatus comprising:
- an elongated body having a column strength sufficient to resist buckling at compressive forces of at least 10 N;
- and
- a nerve cuff engagement region at a distal end of elongated body, configured to releasably secure to a nerve cuff electrode, wherein the nerve cuff engagement region comprises a flared-open distal-facing region chamber configured to at least partially enclose the nerve cuff electrode.
(canceled)
A nerve cuff deployment apparatus for minimally invasively attaching a nerve cuff electrode to a patient's nerve root, the apparatus comprising:
- an elongated body having a column strength sufficient to resist buckling at compressive forces of at least 10 N, wherein the elongated body comprises a first half and a second half, each extending distally to proximally;
- and
- a nerve cuff engagement region at a distal end of elongated body, configured to releasably secure to a nerve cuff electrode, wherein the nerve cuff engagement region further comprises a first capsule portion at the distal end of the first half and a second capsule portion at the distal end of the second half, wherein the first and second capsule portions are configured to form a capsule to enclose and protect the nerve cuff electrode.
