Publication number: 20240108865Abstract: A non-occluding drug-coated balloon catheter device for use in a blood vessel transporting blood comprises a catheter shaft including a guidewire lumen, a fluid lumen and a connector port. A balloon is mounted on the catheter shaft and includes an outer envelope surrounding the guidewire lumen in fluid communication with the fluid lumen; a drug coating applied on the exterior surface of the outer envelope; and at least one bypass lumen forming a passage extending from the proximal end of the outer envelope to the distal end of the outer envelope. When the balloon is positioned in a blood vessel and inflated, the exterior surface of the outer envelope presses the drug coating against the blood vessel and the bypass lumen is open between the distal end of the outer envelope and the proximal end of the outer envelope such that blood transport continues through the bypass lumen.Type: ApplicationFiled: December 12, 2023Publication date: April 4, 2024Inventors: Vijay Sitharam Ramanath, Brett Allyn Williams

Patent number: 11904107Abstract: The disclosure describes a reinforced catheter system, such as a wire, that includes an inner layer having an inner lumen configured to allow an object to slideably move within the inner lumen. The catheter system may include a reinforcement structure, having an outer coating, such as a polymer. The reinforcement structure may be coupled over the inner layer to thereby at least partially encapsulate the inner layer. The catheter system may include an outer surface coupled over the reinforcement structure and the inner layer to thereby encapsulate both the inner layer and the reinforcement structure. The outer coating of the reinforcement structure may be re-flowed to thereby bond the inner layer to the outer surface to thereby create a reinforced homogeneous structure.Type: GrantFiled: March 11, 2019Date of Patent: February 20, 2024Assignee: LightningCath, Inc.Inventors: Brady Hatcher, Randy Beyreis, Brett Allyn Williams

Publication number: 20220175512Abstract: Devices and methods for treatment of bodily lumens and sphincters are disclosed. Some embodiments include methods and devices for inducing an inflammatory response and development of fibrosis, collagen, and/or scar tissue. In some embodiments, scaffolds may be composed of a matrix of filaments. Application of the methods and devices disclosed herein to treat Gastroesophageal Reflux Disease (GERD) and other sphincter disorders are discussed. Biodegradable scaffolds configured to induce an inflammatory response are also disclosed.Type: ApplicationFiled: February 25, 2022Publication date: June 9, 2022Inventors: Robert A. Ganz, Gabriel L.

Publication number: 20220118261Abstract: A pacing lead for temporary atraumatic placement via transvascular access on an endocardial surface of a heart chamber of an animal body. The pacing lead body has a curled shaft at the distal end region of the pacing lead body having a plurality of electrode sites. Each of the electrode sites is individually connected via an electrode conduction wire to a switch box, which receives generator signals from a pulse generator and directs the electrode generator signal to specific electrode sites. A push-pull element is connected to the lead body distal end. A tension-compression member connects to the push-pull element and provides tension and compression to the push-pull element.Type: ApplicationFiled: October 20, 2020Publication date: April 21, 2022Inventors: Wesley Robert Pedersen, Paul Sorajja, Brett Allyn Williams, William J. Drasler

Publication number: 20140336692Abstract: The present invention provides a compliant balloon for use with a catheter having an inner compliant inner layer defining a cylindrical lumen encased by a fiber layer including non-braided inelastic fibers imparting integrity to the balloon wall. The balloon further includes radiopaque material which may be disposed over substantially the entire length of the balloon as a coating or by incorporation within the fiber layer or an outer coating layer. The balloon is expandable from a folded deflated state to an inflated state by increasing pressure within the balloon and can be used with saline as the sole inflation medium to allow rapid deflation as compared to use of a balloon with a contrast medium.Type: ApplicationFiled: July 24, 2014Publication date: November 13, 2014Inventors: Steven J. Allex, Donald Geer, Brett Allyn Williams, Brady Jon Hatcher, Tristan Lynn Tieso
