An endoscopic resection assembly includes an adaptor configured to adapt to an endoscopic device. A pusher is disposed on the adaptor by inserting the adaptor into the central opening defined by the pusher. A cutting device includes a snare loop and a snare drive cable, and is removably coupled to the pusher. The cutting device is configured to resect a tissue when the snare loop is contracted by activation of the snare driver. A clip for engaging onto the tissue can be loaded onto the adaptor at a position distal to the pusher.

A device includes a capsule along with first and second clip arms, proximal ends of which are received within the channel so that the first and second clip arms are movable relative to one another between an open configuration and a closed configuration. A deployment mechanism includes a tension member connected to a proximal end of the first and second arms, a yoke releasably coupled to the tension member and longitudinally movable relative to the capsule to move the first and second arms between the open and closed configurations. The tension member and yoke are configured to separate from one another in response to a predetermined proximal force relative to the tension member. A locking mechanism is coupled to the deployment mechanism and is configured to engage the capsule to lock the one-piece clipping element in the closed configuration, when the yoke is separated from the tension member.

A medical device forming method, an applier for manipulating clips, and a cartridge for holding clips are disclosed herein.

A gastrocutaneous closure device allows gastrocutaneous fistula closure from external abdominal access through the fistula site. Access through the fistula ensures accurate closure placement on the interior lumen wall of the stomach. A closure or clip has a plurality of prongs defined by a deformable material, such that the prongs extend radially from a central hub in an arcuate or curved, semicircular shape. The arcuate shape converges towards a central point or axis at a distal end, and the proximate end of the prongs attaches to the central hub such that the prongs radiate from the hub and the distal end curves back toward the axis through the hub. The deformable prongs may therefore radially compress or retract to define a larger or smaller diameter. The fistula lies on the axis such that the biased, inserted prongs pull the inner stomach wall closed around the healing fistula.

A device includes a capsule extending longitudinally from a proximal end to a distal end and including a channel extending therethrough. The capsule is releasably coupled to a proximal portion of the device. Device also includes a first arm rigidly fixed to the distal end of the capsule to extend distally therefrom. In addition, Device includes a second arm, a proximal end of which is slidably received within the capsule so that the second arm is movable between an open configuration, in which the second arm is moved laterally away from the first arm and a distal end of the second arm is moved distally past the distal end of the first arm, and a closed configuration, in which the second arm is moved toward the first arm and the distal end of the second arm is moved proximally toward the distal end of the first arm.

A clipping device includes a capsule including a longitudinal body and a cap mounted over a distal end thereof so that the cap is movable relative to the longitudinal body from a pre-deployed configuration to a deployed configuration in which the cap, is moved proximally relative to the longitudinal body to reduce a length of the capsule. A channel of the cap and a channel of the capsule are substantially aligned with respect to one another. At least proximal portions of a pair of clip arms are received within the channels of the cap and the longitudinal body so that the clip arms are movable relative to the capsule between an open configuration, in which distal ends of the clip arms are separated from one another, and a closed configuration, in which the distal ends of the clip arms are drawn toward one another.
