Abstract:
A handle for a medical device includes a distal portion extending longitudinally and including a distal channel extending therethrough, the distal end of the distal portion including a connector configured to connect to a proximal end of an endoscope, a central portion slidably connected to the distal portion, the central portion extending longitudinally. The handle also includes a central channel extending therethrough, the distal end of the central portion connected to a sheath, the central portion including an introducer port extending laterally therefrom so that an auxiliary tool inserted through the introducer port is directed through a lumen of the sheath. Further, the handle includes a proximal portion slidably connected to the central portion, the proximal portion extending longitudinally and including a proximal channel extending therethrough, the distal end of the proximal portion connected to a needle so that the needle is passed through the lumen.
Abstract:
Exemplary medical devices may include a snare device. The snare device may include a first leg having a proximalmost end and a second leg having a proximalmost end. The first leg and the second leg may form a distal loop. The proximalmost end of first leg may be independently moveable relative to the proximalmost end of the second leg.
Abstract:
The present disclosure relates to the field of endoscopy. In particular, the present disclosure relates to systems and methods for dissecting large areas of submucosal tissue. The system may apply tension to and continuously manipulate mucosal tissue such that large lesions may be dissected by a cutting element disposed at the distal end of an endoscope.
Abstract:
Embodiments of the present disclosure include medical devices and related methods of use, and manufacture thereof. The medical device may include a snare including an elongate actuation member and a distal snare member. The medical device may further include a snare support including first and second arms and a base member disposed proximate to the elongate actuation member. The first arm may extend from the base member to a first lateral portion of the distal snare member and the second arm may extend from the base member to a second lateral portion of the distal snare member opposite the first lateral portion. Each arm may be moveably coupled to the distal snare member.
Abstract:
A medical device for resecting tissue. The medical device includes a catheter shaft having a proximal portion and two or more distal branch portions. The distal branch portions are moveable between a closed position, and an open position. One or more lumens extend between the proximal portion and through each distal branch portion. An actuation element extends through the lumen of each distal branch portion. A snare loop is connected to each actuation element.
Abstract:
A medical device may include tubular member having a proximal end, a distal end, and a lumen extending therebetween. The tubular member may include an opening at a distal portion of the tubular member, wherein the opening is in communication with the lumen, wherein a distal end of the opening is disposed proximate of the distal end of the tubular member, and wherein the distal portion of the tubular member is configured to bend in at least one plane. The medical device may further include an actuation member extending at least partially within the tubular member, wherein a distal portion of the actuation member is configured to exit the tubular member at a location proximate the opening, wherein a distal end of the actuation member is coupled to the distal end of the tubular member, and wherein pulling the actuation member proximally is configured to cause the distal portion of tubular member to form a loop with itself.
Abstract:
A device for tissue resection and methods of using the same is disclosed, including a snare loop and a tubular handle. The snare loop has both conductive and insulated portions such that the snare loop can be used to cut tissue selectively to make perimeter cuts on the tissue to be resected. The snare loop may be placed and tightened on a target tissue and may be activated for cutting the tissue to be resected by passing an electrical current through the snare loop. Some embodiments of the device include a hood and cutting wire for making perimeter cuts on the tissue to be resected.
Abstract:
Embodiments of the present disclosure include a method for treating tissue. The method may include delivering a medical device through a channel of an endoscopic device, wherein the medical device may include an elongate member, a cap coupled to a distal end of the elongate member and having a cavity, and an electrically-conductive tool extending into the cavity of the cap. The method may also include extending a portion of the medical device out of the channel of the endoscopic device and to the tissue, drawing a portion of the tissue into the cavity of the cap, electrically activating the tool to pierce the portion of the tissue, and cutting the tissue by moving the medical device along a plane of the tissue.
Abstract:
A tissue resection hood and related method of use for resecting the tissue are described. The tissue resection hood may include a distal end portion having an opening, a proximal end portion, and a cavity defined between the proximal and distal end portions, wherein the proximal end portion defines an opening configured to couple to an end of a sheath. The tissue resection hood may further include a cutting member configured to traverse the opening in the distal end portion and a mechanism configured to control a dimension of the cavity.
Abstract:
A device for treating a tissue opening includes a proximal portion including an elongated flexible member, a capsule releasably coupled to a distal end of the flexible member and including a lumen extending therethrough and a clip including a pair of arms movably housed within the capsule. A suture extending along a first one of the pair of arms and including a loop at a distal end thereof extending across an opening extending through the first one of the pair of arms. A suture grabbing element extending laterally from a second one of the pair of arms and including a hook so that, when the pair of arms are moved toward a closed configuration, the hook extends through the opening to grab the loop and draw the distal end of the suture from the first one of the pair of arms toward the second one of the pair of arms.
