Patent ID: 7850607

Claim:
A method for retracting tissue during surgery, said method comprising: a) using a deployment tool to introduce an elongate swivel distally into a body cavity and through the tissue to be retracted, the swivel having a proximal end and a substantially conical distal end tip, a first length of string extending from said proximal end of said swivel, and a second length of string extending from a point substantially midway between said proximal end and said distal end tip of said swivel; and b) pulling on the second length of string from outside the body cavity to cause said elongate swivel to swivel off of said deployment tool and to be oriented substantially perpendicular to said second length of string, until the tissue is retracted; wherein: said deployment tool has a key and said proximal end of said elongate swivel has a keyway, said key engaging said keyway, wherein said pulling on the second length of string causes said keyway to swivel off of said key.
