Patent Issued for Neural Stimulation Systems, Devices and Methods

May 5, 2014

By a News Reporter-Staff News Editor at Cardiovascular Week -- Cardiac Pacemakers, Inc. (St. Paul, MN) has been issued patent number 8706212, according to news reporting originating out of Alexandria, Virginia, by NewsRx editors (see also Cardiac Pacemakers, Inc.).

The patent's inventors are Ternes, David (Roseville, MN); Kramer, Andrew P. (Stillwater, MN); Libbus, Imad (St. Paul, MN); Stahmann, Jeffrey E. (Ramsey, MN).

This patent was filed on December 13, 2006 and was published online on April 22, 2014.

From the background information supplied by the inventors, news correspondents obtained the following quote: "Neural stimulation has been the subject of a number of studies and has been proposed for several therapies. Direct electrical stimulation of parasympathetic nerves can activate the baroreflex, inducing a reduction of sympathetic nerve activity and reducing blood pressure by decreasing vascular resistance. Sympathetic inhibition, as well as parasympathetic activation, have been associated with reduced arrhythmia vulnerability following a myocardial infarction, presumably by increasing collateral perfusion of the acutely ischemic myocardium and decreasing myocardial damage. Modulation of the sympathetic and parasympathetic nervous system with neural stimulation has been shown to have positive clinical benefits, such as protecting the myocardium from further remodeling and predisposition to fatal arrhythmias following a myocardial infarction."

Supplementing the background information on this patent, NewsRx reporters also obtained the inventors' summary information for this patent: "Various system embodiments comprise circuitry to determine when an arrhythmia has terminated, and a neural stimulator adapted to temporarily deliver a neural stimulation therapy to assist with recovering from the arrhythmia in response to termination of the arrhythmia. Various method embodiments comprise determining that an arrhythmia has terminated and temporarily delivering a neural stimulation therapy to assist with recovering from the arrhythmia upon termination of the arrhythmia. Various method embodiments comprise chronically performing a prophylactic neural stimulation therapy, temporarily delivering an arrhythmia therapy, an apnea therapy, or a pain therapy in response to a therapy trigger, and chronically performing the prophylactic neural stimulation therapy upon completion of the arrhythmia therapy, the apnea therapy or the pain therapy. Various method embodiments comprise delivering a pretherapy stimulation in preparation for delivering a therapy in response to a therapy trigger, delivering the therapy, and delivering a post-therapy neural stimulation to assist with recovering from the therapy upon completion of delivering of the therapy.

"This Summary is an overview of some of the teachings of the present application and not intended to be an exclusive or exhaustive treatment of the present subject matter. Further details about the present subject matter are found in the detailed description and appended claims. Other aspects will be apparent to persons skilled in the art upon reading and understanding the following detailed description and viewing the drawings that form a part thereof, each of which are not to be taken in a limiting sense. The scope of the present invention is defined by the appended claims and their equivalents."
