News editors obtained the following quote from the background information supplied by the inventors: "There are a number of implantable medical devices (IMDs) that deliver electrical therapy, and others have been proposed. By way of example and not limitation, IMDs include implantable cardiac rhythm management (CRM) such as cardiac pacemakers, cardioverters, and defibrillators. CRM devices provide electrical stimulation to selected chambers of the heart in order to treat disorders of cardiac rhythm. An implantable pacemaker, for example, is a CRM device that paces the heart with timed pacing pulses. Other IMD examples include spinal cord stimulators, muscle stimulators, and nerve stimulators. For example, it has been proposed to stimulate neural targets (referred to as neural stimulation, neurostimulation or neuromodulation) to treat a variety of pathological conditions. For example, research has indicated that electrical stimulation of the carotid sinus nerve can result in reduction of experimental hypertension, and that direct electrical stimulation to the pressoreceptive regions of the carotid sinus itself brings about reflex reduction in experimental hypertension. Additionally, devices other than implantable devices may deliver electrical stimulation. An example of such devices includes transcutaneous electrical nerve stimulation (TENS) devices."
As a supplement to the background information on this patent application, VerticalNews correspondents also obtained the inventors' summary information for this patent application: "Various embodiments of a system for detecting a concurrent electrical therapy applied to a patient comprise an implantable medical device (IMD) configured to be implanted in the patient and configured to detect the concurrent electrical therapy. The concurrent electrical therapy includes a plurality of electrical therapy pulses. The IMD includes a storage, concurrent therapy detection circuitry, and a controller. The storage includes at least one characteristic of the therapy pulses in the concurrent electrical therapy. The concurrent therapy detection circuitry is configured to detect electrical pulses and to extract at least one characteristic of the detected electrical pulses. The controller is configured to compare the at least one characteristic of the detected electrical pulses to the at least one stored characteristic of the therapy pulses and to declare that the concurrent therapy is being applied to the patient if the at least one characteristic of the detected electrical pulses favorably compare to the at least one stored characteristic of the therapy pulses.
"Various method embodiments detect a concurrent therapy, where the concurrent therapy includes a plurality of therapy pulses. Detecting the concurrent therapy includes detecting at least one electrical pulse, extracting at least one characteristic from the at least one electrical pulse, comparing the at least one characteristic of the detected pulse to at least one characteristic of therapy pulses, and detecting that the concurrent therapy is being applied if the at least one characteristic of the detected pulse favorably compares to the at least one characteristic of the therapy pulses.
