Publication number: 20230346387Abstract: The present disclosure relates to compression clips, and more specifically, to compression clips delivered to a target site through an endoscope for use in tissue resection, for example, within the gastrointestinal tract. In examples, clips are configured to be actuatable in response to a compressive force to transition between an open configuration and a closed configuration. In an embodiment, a tissue clipping device may include a first member with a plurality of arms. Each of the arms may extend from a first end to a second end, and the first end of each arm may be received within the first member. The arms may be movable between the open configuration and the closed configuration. A second member may be slidably disposed with respect to the first member.Type: ApplicationFiled: June 30, 2023Publication date: November 2, 2023Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Oscar R. Carrillo, JR., James J. Scutti, Routha Sim, Katie Olmeda, Todd M. Pfizenmaier, Barry Weitzner

Patent number: 11399821Abstract: A control handle for use with a suture device operable through an endoscope includes a grip attachment configured to be secured to an endoscope and a control housing operably secured to the grip attachment. A catheter housing is moveably disposed within the control housing and adapted to releasably secure the suture catheter such that translation of the catheter housing causes translation of the suture catheter. A lever is rotatably securable relative to the catheter housing such that rotation of the lever relative to the catheter housing causes the catheter housing to move relative to the control housing. A sliding tab is disposed relative to the lever such that movement of the sliding tab relative to the lever causes the suture catheter to translate relative to the control wire disposed within the suture catheter.Type: GrantFiled: June 19, 2019Date of Patent: August 2, 2022Assignee: Boston Scientific Scimed Inc.Inventors: Christopher R. Deuel, Shaun D. Comee, Kevin Windheuser, Todd M. Pfizenmaier, Briana J. Moretti, Stan Gilbert, Thomas Jones, Ashrita Raghuram, Andrew Jones, Evan Hunter Williams, Brian Yoo
