Abstract
Endovascular lead design and delivery systems are described herein. One variation of an endovascular lead apparatus may generally comprise an elongate body having a proximal portion and a distal portion, one or more electrodes positioned along a first side of the distal portion, a tray positioned along a second side of the distal portion opposite to the first side, and one or more frame members positioned along the tray and which are reconfigurable from a low-profile delivery configuration to an expanded deployed configuration, wherein expansion of the one or more frame members to the expanded deployed configuration reconfigures the distal portion into contact against a tissue wall for energy delivery via the one or more electrodes.
Claims9
A method of stimulating a nerve, comprising:
- advancing an elongate body within a vessel and into proximity of a nerve body to be stimulated;
- confirming a location of the nerve body via one or more mapping electrodes positioned along a mapping sleeve which is configured to isolate the one or more mapping electrodes from the elongate body;
- and
- exposing a distal end of the elongate body by retracting the mapping sleeve relative to the elongate body once the location of the nerve body is confirmed such that an inner sleeve having one or more frame members is exposed along the distal end;
- reconfiguring the one or more frame members to urge one or more treatment electrodes along the inner sleeve into contact against an inner surface of the vessel;
- actuating the one or more treatment electrodes positioned against the inner surface to deliver a treatment stimulation through the inner surface and into the nerve body.
