Abstract:
A system for tissue dissection and retraction is disclosed herein. A tissue dissection assembly generally comprises an elongate body shaft, an actuation member movable relative to the elongate body shaft, and at least one dissector arm member having at least a first end attached to the elongate body shaft, wherein the at least one dissector arm member is adapted to reconfigure within a plane from a low profile to an expanded profile when urged via the actuation member, and wherein the at least one dissector arm is further adapted to dissect tissue within the plane. In use, the assembly dissects tissue within the plane typically by advancing the elongate body shaft into the tissue region where the dissector arm member or members are then reconfigured within the plane from its low profile to its expanded profile to thereby dissect the tissue region along the plane.
