摘要： An insert or elongate member divides the lumen of an elongated medical device, such as the working channel of an endoscope, into two or more secondary lumens. The insert or elongate member thereby improves the ability of the lumen of the elongated medical device to accommodate multiple items or uses. The insert or elongate member is capable of securing one item, such as a pull line, such that it does not interfere with another item positioned in the lumen of the elongated medical device or with another use of the lumen of the elongated medical device. In accordance with some embodiments, a ligating instrument comprises a ligating band dispenser, a pull line, and an elongate member having a dividing wall structure or a plurality of lumens, wherein the elongate member divides a working channel of an endoscope into a plurality of secondary lumens.

摘要： A device for passing a needle and suture longitudinally through a target tissue includes a proximal jaw including a proximal recess and a proximal retention mechanism for releasably engaging a first end of a needle received within the proximal recess and a distal jaw movably coupled to the proximal jaw such that the proximal and distal jaws are longitudinally movable relative to one another. The distal jaw includes a distal recess and a distal retention mechanism for releasably engaging a second end of the needle received within the distal recess. The proximal and distal jaws are movable between a first state, in which the proximal retention mechanism is in a locked configuration and the distal retention mechanism is in an unlocked configuration, and a second state, in which the proximal retention mechanism is in an unlocked configuration and the distal retention mechanism is in a locked configuration.

摘要： The present disclosure relates to the field of tissue dissection. Specifically, the present disclosure relates to medical devices which lift and retract tissue during a dissection procedure to improve visualization of the target tissue and mitigate obstruction of dissection tools. In particular, the present disclosure relates to a tissue retraction device which moves from a constrained to relaxed configuration to immobilize and retract the dissected portion of target tissue during a dissection procedure.

摘要： A device for treating a tissue includes a capsule extending longitudinally from a proximal end to a distal end and including a channel extending therethrough, the capsule releasably coupled to a proximal portion of the device and clip arms, proximal ends of which are slidably received within the channel of the capsule so that the clip arms are movable between an open configuration, and a closed configuration. A core member is coupled to the clip alms, the core member including a proximal portion and a distal portion releasably connected to one another so that, when the core member is subjected to a predetermined load, the proximal and distal portions are separated from one another. An electrically conductive control member is connected to the core member, a proximal end of the connected member connected to a power source for delivering an electrical current to the clip arms.

摘要： This disclosure provides design, material, manufacturing method, and use alternatives for medical devices. An example medical device may include a medical device for delivery of a surgical closure member. The medical device includes an elongate tubular member having a proximal end, a distal end and a lumen extending therein. The elongate tubular member is adapted to be delivered through the working channel of an endoscope and the lumen is adapted to receive a surgical closure member. The medical device also includes a tissue support extending from the distal end of the elongate tubular member. The tissue support includes a support surface and the support surface is adapted to support tissue as a surgical closure member engages the tissue thereon.
