Publication number: 20240108486Abstract: Systems and methods for anchoring and restraining gastrointestinal prostheses are disclosed. In various examples, the systems and methods include securing a gastrointestinal device within a patient's anatomy by extending an anti-migration anchor through a plurality of portions of the gastrointestinal device to couple together the plurality of portions of the gastrointestinal device. In some examples, the anti-migration anchor extends through tissue situated between the plurality of portions of the gastrointestinal device.Type: ApplicationFiled: July 12, 2023Publication date: April 4, 2024Inventors: Kedar R. Belhe, Werner Schwarz, Todd Stangenes

Publication number: 20240082034Abstract: Several gastrointestinal surgery procedures are effective as treatments for metabolic disorders such as obesity and diabetes. Minimally invasive procedures including intra-luminal gastrointestinal implants have been proposed to mimic the anatomical, physiological and metabolic changes achieved by these procedures. Many of these designs include long sleeve like elements that prevent contact of food with the walls of the small intestine. It is desirable to have simple delivery systems that can place these implants under endoscopic guidance. However, in order to anchor these sleeve elements safely and reliably, the inventors have previously disclosed anchoring means that anchor the sleeves at the junctions of the stomach and the intestine or the stomach and esophagus.Type: ApplicationFiled: August 16, 2023Publication date: March 14, 2024Inventors: Kedar R. Belhe, Paul J. Thompson, Alexander D. Grafov, Werner Schwarz

Patent number: 10182860Abstract: An electrode catheter and a method for assessing electrode-tissue contact and coupling are disclosed. An exemplary electrode catheter comprises an electrode adapted to apply electrical energy. A measurement circuit is adapted to measure impedance between the electrode and ground as the electrode approaches a target tissue. A processor determines a contact and coupling condition for the target tissue based at least in part on reactance of the impedance measured by the measurement circuit. In another exemplary embodiment, the electrode catheter determines the contact and coupling condition based at least in part on a phase angle of the impedance.Type: GrantFiled: February 2, 2016Date of Patent: January 22, 2019Assignee: St. Jude Medical, Atrial Fibrillation Division, Inc.Inventors: Saurav Paul, Hong Cao, Kedar R.
