Latest Patents

One of his latest patents is the "Gastro-intestinal pacemaker having phased multi-point stimulation." This portable or implantable gastric pacemaker includes multiple electrodes that can be positioned on the inner or outer surface of an organ in the gastro-intestinal tract. These electrodes are individually programmed to deliver phased electrical stimulation to pace peristaltic movement of material through the GI tract. The pacemaker accommodates variations in pulse amplitudes, pulse durations, pulse periods, and relative pulse phasing among the electrodes. Computer control can adjust and vary all stimulation parameters delivered by the electrodes to achieve effective treatment and re-training of an organ for natural pacing. This device can be programmed to enhance or accelerate peristaltic movement through the gastric tract or to attenuate it to treat conditions such as eating disorders or diarrhea.

Another significant patent is the "Catheter for esophageal perfusion." This esophageal perfusion catheter features an outer housing and multiple flexible, tubular channel members within it. It includes at least two spaced balloon members encompassing the catheter. Two of the channel members are in fluid communication with the balloons, while others serve various functions such as esophageal perfusion aspirating and gastric aspirating channels. The design allows for effective fluid management and treatment in the esophagus.
