Internal tissue retractor
First Claim
1. A method for temporarily repositioning tissue in a surgical procedure comprising:
- inserting a temporary tissue repositioning device through an incision into a body cavity, the temporary tissue repositioning device comprising;
a bendable frame comprising;
a first axis and a second axis intersecting the first axis;
a surface defined by the first axis and the second axis;
a first side and a second side defined by the surface;
a plurality of elongate first bending portions parallel to the first axis and parallel to each other; and
a plurality of second bending portions, operatively coupled to the first bending portions; and
a fabric cover disposed over the first side of the frame, the fabric cover adapted to retain tissue and the fabric cover defining a tissue retention surface,whereinthe bendable frame is reversibly and manually bendable between a first state and a second state;
in the first state, the bendable frame is flattened such that the tissue retention surface is generally planar;
in the second state, the bendable frame is bent into a nonplanar configuration such that the tissue retention surface is nonplanar;
the frame in the first state remains in the first state;
the frame in the second state remains in the second state; and
the fabric cover disposed over the first side conforms to the surface in the first state and the second state;
wherein inserting the temporary tissue repositioning device through the incision into the body cavity comprises inserting the temporary tissue repositioning device through the incision into an abdominal cavity;
deforming the repositioning device into the second state; and
repositioning tissue away from a surgical workplace.

Abstract
A positionable internal retraction device is provided comprising a malleable ring member and a web-like structure. The retraction device operates to temporarily reposition tissues and organs from an operative site to provide a clear access and visual path for the surgeon. The ring member may be elongated, twisted, folded, bent or deformed to provide an appropriate insertion profile and subsequent functional shape. The retraction device may be shaped for both open and minimally invasive surgeries. The retraction device is atraumatic and may be used for retraction of delicate tissues and organs. The ring member may have different bending biases. The web-like structure may be constructed of any elastic material that can stretch and recover from the shaping and reshaping of the ring member.
