Endoscopic tissue stabilization device and related methods of use

Abstract

Embodiments of the invention include a sleeve for use in a body lumen defined by body tissue. The sleeve includes a collapsible wall defining a lumen and including an inflatable member configured to increase a volume of the lumen when the inflatable member is in an inflated state, a conduit configured to inflate the inflatable member, and a port defined by the collapsible wall and in flow communication with the lumen.
