Mucosal resection device and related methods of use

摘要

A resection device for resecting tissue from a body. The device includes an elongate member having a proximal end, a distal end, and a lumen extending from the proximal end to the distal end. The device further includes a cap assembly configured;to be coupled to the distal end of the elongate member. The cap assembly may include a first cap defining a resection loop channel and a distal end having a first opening. The assembly may further include a second cap configured to receive a portion of the first cap. The second cap includes a distal end having a second opening. A distal portion of the first cap and a distal portion of the second cap may cooperate to define a resection loop track for receiving a resection loop.

1. A tissue resection device, comprising:
an end cap assembly, including:
a first cap portion having a proximal end region and a distal end region,a second cap portion having a proximal end region, a distal end region terminating distally at a distalmost surface of the second cap portion, and an internal chamber, wherein the second cap portion is received within the first cap portion such that the proximal end region of the first cap portion concentrically surrounds the proximal end region of the second cap portion, and the distal end region of the first cap portion concentrically surrounds the distalmost surface of the second cap portion, anda channel extending between the first cap portion and the second cap portion, and opening into the internal chamber of the second cap portion.
