IMPLANTABLE NEUROSTIMULATOR FOR MODULATING CARDIOVASCULAR FUNCTION

摘要

An implantable medical device includes an implantable capsule housing a circuit that delivers neurostimulation to modulate one or more cardiovascular functions. To limit displacement after implantation, a fixation device is coupled to the implantable capsule to fix the miniature implantable medical device to a position in the body of a patient. In various embodiments, the fixation device include one or more of a suture loop, a cuff to wrap around a cylindrical structure such as a nerve of a vessel, and a transmural fixation device anchoring on the interior surface of a wall defining a cavity in the body.
