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

Publication number: 20200352764Abstract: Devices for palliating gastrointestinal strictures using rapid exchange type enteral stent placement catheters. The catheter may include an inner member and an outer member, with the two members being slidable with respect to one another. In various device embodiments, a ramp for directing a guidewire out from within the catheter is provided using portions of the outer member or a shaped mandrel. The inner member may take a number of forms, including a tubular distal portion, a skived or integrally attached elongate midsection, and a proximal portion. A mandrel can be used in a portion proximal of the guidewire ramp, with the mandrel taking one of several disclosed forms.Type: ApplicationFiled: July 28, 2020Publication date: November 12, 2020Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: GARY A.

A tubular prosthesis is disposed on the catheter over at least a portion of the balloon and a portion of the constraint. The tubular prosthesis has a contracted condition and an expanded condition. The tubular prosthesis is initially disposed on the catheter in the contracted condition. Further, a balloon catheter includes a constraint so that the balloon may be sequentially inflated for dilatation purposes such as in a valvuloplasty operation.Type: GrantFiled: October 1, 2001Date of Patent: March 29, 2005Assignee: Boston Scientific CorporationInventors: George T.
