Patent ID: 8734478

Claim:
A rectal manipulation device, comprising: a shaft assembly defining an insertion axis, wherein at least a portion of said shaft assembly is configured to be inserted into a patient's rectum; and a plurality of tissue manipulation arms each having a tissue manipulation end, each said tissue manipulation arm operably supported by said shaft assembly, wherein at least some of said tissue manipulation arms are selectively movable from a first insertion position wherein all of said tissue manipulation ends are substantially aligned relative to each other and, upon application of an actuation motion thereto, said at least some of said tissue manipulation arms move to other deployed positions about said insertion axis such that said tissue manipulation ends of said plurality of tissue manipulation arms are not all substantially aligned relative to each other and wherein one of said at least some of said tissue manipulation arms is constrained to move along a corresponding transverse axis that is substantially transverse to said insertion axis from said first insertion position to one of said other deployed positions upon application of said actuation motion thereto and wherein another one of said at least some of said tissue manipulation arms is constrained to move along another corresponding transverse axis that is substantially transverse to said insertion axis and parallel to said corresponding transverse axis from said first insertion position to another one of said other deployed positions upon application of said actuation motion thereto.
