Patent number: 8965512Abstract: System and methods for adhering a patch of stimulation electrode(s) to blood vessels to stimulate a target site on the blood vessel are described. In various embodiments, the system includes an adhesion patch and at least one electrode. The adhesion patch includes a passive adhesion mechanism that may produce an adhesive force sufficiently strong to adhere the adhesion patch to the exterior of the blood vessel and to operationally position the at least one electrode for use in electrically stimulating a target site of the blood vessel. The adhesion patch may also include a release mechanism that is configured for a user to disengage the patch from the exterior of the blood vessel without significant trauma to the blood vessel. After being released, the adhesion patch may be re-adhered to a different target site of the blood vessel and stimulate the different target site.Type: GrantFiled: December 12, 2013Date of Patent: February 24, 2015Assignee: Cardiac Pacemakers, Inc.Inventors: Allan C. Shuros, Ismail Guler, Richard Charles Gunderson, Joel P. Grover, Eric A. Mokelke, Adam David Grovender
