High frequency stimulation to block laryngeal stimulation during vagal nerve stimulation

摘要

An implantable medical device and associated method deliver a therapy to an autonomic nerve. The therapy delivery includes delivering therapeutic low frequency (LF) electrical stimulation pulses to the autonomic nerve and delivering a high frequency electrical signal to the autonomic nerve during the LF frequency stimulation pulse delivery. The high frequency stimulation signal blocks activation of autonomic nerve fibers innervating a non-targeted tissue during the therapeutic LF stimulation pulse delivery.

主权项

1. An implantable medical device for electrically stimulating an autonomic nerve, comprising;
an electrode pair adapted for positioning along the autonomic nerve; a therapy delivery module coupled to the electrode pair, the therapy delivery module comprising
an electrical stimulation pulse generator for delivering stimulation pulses at a first frequency to the autonomic nerve via the electrode pair;a high frequency signal source for delivering a high frequency electrical signal at a second frequency higher than the first frequency to the autonomic nerve via the electrode pair; and a control module configured to control the therapy delivery module to deliver the first frequency stimulation pulses to excite a target tissue innervated by the autonomic nerve and deliver the high frequency signal during the first frequency stimulation pulse delivery; and wherein the pulse generator and the high frequency signal source are coupled to the electrode pair.
