Claim Text:
1. An endoscopic surgical device for retrieving severed tissue or foreign bodies from within a human body, the device comprising: a. a support unit comprising: b. a tissue retrieving net system comprising: c. said second passage having a diametrical extent substantially smaller than the width of said loop as deployed, said introducer member engaging said loop at said opening and resiliently collapsing and elongating said loop as said net is retracted and moves into said second passage, said loop resiliently returning to its uncollapsed configuration as it is deployed; d. said net system further comprising a first connector fixed to each of said relatively parallel and flexible loop cables, a second connector fixed to each of said relatively parallel and flexible loop cables and proximal to said opening relative said first connector, and an intermediate portion defined by an axial length of each of the two relatively parallel and flexible loop cables, extending between the first connector and the second connector, in which the two relatively parallel and flexible loop cables are unattached from each other along the entire length between the first connector and the second connector, wherein a proximal side of said net element is secured to the loop within the intermediate portion between the first connector and the second connector by a tether at a location adjacent the second connector; wherein the first connector is axially disposed a predetermined distance from the second connector, such that only one of the first and second connectors is within an articulation zone which is defined by the two relatively parallel and flexible loop cables being bended at an angle of greater than 200 degrees at a radius of 0.75 inches or less.
