Abstract

A retractor member is configured for insertion through a channel of an access member and for moving soft tissue at a treatment site that is accessible through the channel. The retractor includes a body having a proximal end and a distal end and spaced from each other along a longitudinal direction. The distal end defines a retractor blade and the body defines a first surface and a second surface opposite each other along a transverse direction substantially perpendicular to the longitudinal direction. The retractor includes an attachment device configured to selectively attach the body to a portion of the access member such that the body is extendable through the working channel while the body is attached to the portion of the access member.
