Abstract:
1. A tissue manipulation assembly, comprising: an elongate rigid or wholly flexible body shaft which is sized for introduction into a body; an actuation member movable relative to the elongate body shaft; and a first arm member and a second arm member each having at least a distal end attached to a distal tip of the elongate body shaft and where each arm member has a feature which increases frictional resistance against tissue contacting the arm members and an area between the arm members remains uncovered, wherein each arm member is positioned along the elongate body shaft opposite to one another such that each arm member reconfigures radially to be set and maintained in one or more intermediate positions via an intermediate stop mechanism whereby each arm member is correspondingly configured within a single plane from a low profile to an expanded curved or arcuate planar profile along a substantial length of each arm member while each proximal end remains longitudinally aligned with the elongate body shaft when urged via the actuation member such that the assembly reconfigures along the single plane, wherein each arm member is further positioned along the elongate body shaft such that each arm member is reconfigurable into an overextended arcuate configuration extending distally beyond the assembly such that each arm member presents a curved outer surface along its length and is shaped to inhibit bending of the overextended arcuate configuration outside the single plane, and wherein the first and second arm members are spaced apart from one another when in the low profile and when in the overextended arcuate configuration.
