Publication number: 20240065752Abstract: A bipolar sphincterotome may include an elongate tubular member, a cutting wire, and a return path. The return path may include a conductive ink portion disposed on an outer surface at a distal portion of the tubular member. The return path may also include a return wire disposed within the tubular member that is electrically coupled to the conductive ink portion. In some example embodiments, the return wire may be disposed within a lumen configured to have two or more functions, one of which being to house the return wire. Additionally, in some example embodiments, the conductive ink portion may be circumferentially disposed on the outer surface to provide visual access to a wire guide lumen. Also, for some example embodiments, the bipolar sphincterotome may include two electrically isolated return paths.Type: ApplicationFiled: October 31, 2023Publication date: February 29, 2024Applicant: Cook Medical Technologies LLCInventors: Tyler Evans McLawhorn, Vihar C.

Patent number: 11503984Abstract: A scope system is provided including an elongate tube with a distal portion and a lumen extending therethrough. The scope system also includes at least one accessory channel extending from a proximal end to a distal end and having with an accessory lumen extending therethrough, the at least one accessory channel movably disposed at least partially within the lumen of the elongate tube. The at least one accessory channel includes a distal section and a forward-viewing configuration and a side-viewing configuration. In the forward-viewing configuration, the distal section of the at least one accessory channel is substantially parallel to the distal portion of the elongate tube and in the side-viewing configuration, the distal section of the at least one accessory channel is arced at a radius greater than a radius of the distal portion of the elongate tube.Type: GrantFiled: February 28, 2017Date of Patent: November 22, 2022Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Vihar C.

Patent number: 11439384Abstract: Among other things, there are shown embodiments of locking mechanisms for holding sutures in tension. Such devices may be used with implants that use or require sutures, and are easily locked remotely. In particular embodiments, a lock includes a housing member, a pin member at least partially within the housing member, and a spring biasing the pin member into the housing member. The pin member includes a gripping portion, and has a retracted condition and a locked condition. When retracted, a suture can move through the housing member and around the gripping portion of the pin member. When locked, the gripping portion of the pin member engages the suture and presses it against the interior of the housing member.Type: GrantFiled: April 25, 2019Date of Patent: September 13, 2022Assignee: Muffin IncorporatedInventors: Shaun Davis Gittard, John C.

Patent number: 11337723Abstract: The present embodiments provide apparatus and methods for treating tissue by applying a force to the tissue. In one embodiment, the apparatus comprises a deployable segment having proximal and distal regions, a main body extending therebetween, and a loop member formed at the distal region of the deployable segment. A cannula having a bore is dimensioned to circumferentially surround at least a portion of the main body at a location proximal to the loop member, and a spring member is disposed between the cannula and the loop member. The proximal end of the spring member is affixed to the cannula, and the distal end of the spring member is movable to apply a compressive force to adjust the size of the opening of the loop member and compress tissue disposed within the opening of the loop member. In an alternative embodiment, the cannula is omitted, and a diameter of the loop member is configured to be reduced and increased any number of times before final deployment of the deployable segment.Type: GrantFiled: October 22, 2020Date of Patent: May 24, 2022Assignee: COOK MEDICAL TECHNOLOGIES LLCInventors: Kenneth F.
