Method, apparatus, and surgical technique for autonomic neuromodulation for the treatment of disease

InactiveUS20060167498A1Reduce or prevent conditionReducing and preventing symptomSpinal electrodesSurgical needlesSplanchnic nervesDisease
The present invention teaches a method and apparatus for physiological modulation, including neural and gastrointestinal modulation, for the purposes of treating several disorders, including obesity, depression, epilepsy, and diabetes. This includes chronically implanted neural and neuromuscular modulators, used to modulate the afferent neurons of the sympathetic nervous system to induce satiety. Furthermore, this includes neuromuscular stimulation of the stomach to effect baseline and intermittent smooth muscle contraction to increase gastric intraluminal pressure, which induces satiety, and stimulate sympathetic afferent fibers, including those in the sympathetic trunk, splanchnic nerves, and greater curvature of the stomach, to augment the perception of satiety.

Methods and Devices for Treating Obesity

InactiveUS20080312678A1Create gastric satietyReducing stomach volumeSurgeryDilatorsLoop of HenleAntrum
Methods and devices for treating obesity. Pressure is applied to gastric walls in at least one segment of a stomach such that the pressure distends the gastric walls and induces satiety. A hollow capsule can be used to distend the gastric walls. Alternatively, a doughnut-shaped ring may be inflated to an amount sufficient to create intragastric tension and induce satiety. A c-ring including at least one balloon may be placed at a segment of the stomach, where the balloon inflates to a size that creates tension at the segment. A biocompatible material can be injected into the fundus and antrum of the stomach to stiffen the gastric wall to create a fullness feeling.

Hard lens calculus removing device

The invention relates to a hard lens calculus removing device, which is of a double-sheath structure. A conical guide head is arranged at a far end of an inner sheath, can enable an outer sheath to be smoothly guided into a cavity (including inner and outer bile duct antrums of a liver, a bile duct antrum, a cholecyst antrum and a renal pelvis) and avoids damage of the outer sheath on circumferential tissues and a fistula wall. Elastic and tensile tissues are arranged around fistula, a lumen and an incision, the fistula and the lumen are in half-closing state when being not filled by liquid, and the diameters of the fistula and the lumen are smaller than the diameter of the outer sheath, thus tissues by the side the incision, the fistula wall, the lumen or a cyst wall surround and extrude the outer sheath so as to realize a seal effect and avoid overflow of internal liquid in the lumen and a cyst antrum. After the hard lens calculus removing device is guided into the lumen, the inner sheath is pulled out and the outer sheath is reserved. A Y-shaped joint is arranged on the outer sheath, and calculus surged along with water is conveniently discharged into a collection bag through a side hole of the Y-shaped joint. Due to a protection function of the outer sheath, various hard endoscopes, including oledochoscopes, hard lenses or percutaneous nephroscope set, and ureteroscope are indirectly in contact with soft tissues by the sides of a kidney fistula wall and a cholecyst incision, thus the damage on incision circumferential tissues, the fistula wall and a lumen wall due to repeated insertion and extraction of the endoscopes and devices is basically avoided, and the safety of an operation is improved.

Methods, systems, and devices for providing a denervating energy treatment to the tissue of the pulmonary vein and antrum region of the left atrium utilizing a catheter-based structure having one or more energy delivery surfaces. In some instances energy delivery surfaces are arranged with a circumferential and axial offset relative to one another. A pattern of individual lesions loosely approximating a helix, or other staggered pattern, or roughly circumferential are placed so as to provide a pattern which covers substantially the circumference of the treated area while avoiding stenosis. Denervating energy is applied by modulation of the energy delivery surfaces using an energy source integrated with a controller and control algorithm. In some instances feedback is used in a control algorithm for energy modulation. Energy sources are radiofrequency, ultrasound, and cryogenic.
