Abstract
An organ retractor includes a tubular introducer which is adapted to be inserted through a body into an underlying body cavity and a multi-fingered tool which is insertable into through the body wall into the body cavity. The fingers are formed of a spring material and have a naturally curved configuration so as to spread out when pushed beyond the distal end of the introducer. A plurality of filaments attached to the fingers provide bridges when the fingers are in the extended positions.
