Publication number: 20240049946Abstract: Improved methods and devices for performing an endoscopic surgery are provided. Systems are taught for operatively treating gastrointestinal disorders endoscopically in a stable, yet dynamic operative environment, and in a minimally invasive manner. Such systems include, for example, an endoscopic surgical suite. The surgical suite can have a reversibly expandable retractor that expands to provide a stable, operative environment within a subject. The expansion can be selectively asymmetric to maximize space for a tool and an endoscope to visualize a target tissue and treat the target tissue from outside the patient in a minimally invasive manner.Type: ApplicationFiled: October 26, 2023Publication date: February 15, 2024Applicant: Boston Scientific Scimed, Inc.Inventors: Barry Weitzner, George T. Roberts, Paul Smith, Gregory Piskun, John T. To, Jeffrey P. Radziunas

Patent number: 10376170Abstract: A mapping catheter including an elongate catheter body extending from a proximal end to a distal end, a handle connected to the proximal end of the catheter body, an electrode array connected to the distal end, a deployment shaft, and an irrigation system. The catheter body includes at least one lumen. The irrigation system includes a manifold and a thin, polymeric irrigation tube. The manifold is disposed within the handle and is connectable to a source of irrigation fluid. The irrigation tube is connected to the manifold and extends around the deployment shaft from the manifold to the distal end of the catheter through the catheter body lumen. The irrigation tube forms an annular lumen between an inner surface of the irrigation tube and an outer surface of the deployment shaft. The annular lumen is configured to carry irrigation fluid from the manifold to the array.Type: GrantFiled: August 9, 2016Date of Patent: August 13, 2019Assignee: Boston Scientific Scimed, Inc.Inventors: William Quinn, Kurt E.

Patent number: 9078697Abstract: A surgical portal apparatus includes a housing and a cannula member. The housing includes a seal mount and a flexible housing wall. The cannula member is connected to the housing and defines a longitudinal axis and passageway. The seal mount has an internal seal. The flexible housing wall is dimensioned to permit both axial and radial movement of the seal mount with respect to the longitudinal axis between a first position of the seal mount and a plurality of second positions of the seal mount. The seal mount may be biased by a biasing member toward the first position. In an embodiment, the biasing member is a spring that is engageable with the cannula member and the seal mount.Type: GrantFiled: March 4, 2010Date of Patent: July 14, 2015Assignee: Covidien LPInventors: Michael E.

Patent number: 8882785Abstract: An endoscopic suturing device that can be employed to suture tissue using endoscopic techniques to place one or more stitches in tissue during a single intubation of an endoscope. The suturing device may include a suturing capsule with a suction chamber that is configured to capture tissue that is to be sutured. A needle is movable along a pathway across the suction chamber to penetrate and place stitches in the captured tissue. A catch is located distal to the suction chamber to receive and retain the suture during a stitching sequence. The catch may be movable along the needle pathway and configured to release the suture when the catch moves a predetermined distance along the pathway. The catch may be configured so that a predetermined amount of force is required to move the catch the predetermined distance required to release the suture.Type: GrantFiled: September 29, 2008Date of Patent: November 11, 2014Inventors: Paul C.
