Techniques for placing medical leads for electrical stimulation of nerve tissue

摘要

This disclosure is directed to extra, intra, and transvascular medical lead placement techniques for arranging medical leads and electrical stimulation and/or sensing electrodes proximate nerve tissue within a patient.

主权项

1. A system configured to deliver electrical stimulation to a patient's vagus nerve, the system comprising a delivery catheter and a deployment member extendable and retractable from a lumen of the catheter, the deployment member including a guidewire, at least one electrode, and a tubular member, the at least one electrode being connected to a distal portion of an implantable medical lead, the lead being advanceabie over the guidewire, and the tubular member including a lumen in which the lead and the guidewire are received such that the lead and the guidewire are advanceable therein; andwherein:
one or both of the tubular member and the guide wire is constructed of a shape memory material to take on an S-shape when the deployment member is advanced out from the lumen of the catheter; and the S-shape is configured to span a well of a vein adjacent to the vagus nerve, when the deployment member extends through the wall.
