摘要: A medical device may include an insertion device having a proximal end, a distal end, and a lumen extending therethrough. The medical device may further include a snare device configured to transition between a contracted state within the lumen of the insertion device, and an expanded state extending distally of the insertion device. The snare device may include a loop including a pair of legs and a distal tip. The distal tip may include a plurality of stabilizers between the pair of legs.

摘要: Systems and methods for treating tissue may include one or more delivery devices, a grasping element, a first ring for anchoring to a wall of a gastrointestinal tract, and a second ring operably couplable to a radially inward surface of the first ring. Other embodiments include methods of treating tissues, including tubular tracts of tissue, comprising coupling a first ring to first tissue of a wall of a tissue tract, relocating a target tissue proximally to a position proximal to the first ring, coupling a second ring to the first ring, and cutting tissue proximal to the interface of the first and second rings.

摘要: A medical device may include an insertion device having a proximal end, a distal end, and a lumen extending therethrough. A snare device may be configured to transition between a retracted state within the lumen of the insertion device, and an extended state extending distally of the insertion device. The snare device may comprise a wire. A member may be disposed within the lumen of the insertion device. The member may be configured to maintain legs of the snare device in an open snare loop configuration in the extended state. In the open snare loop configuration, the wire may include an arcuate loop.
