Abstract
The present invention is an access sheath comprising a tube or sheath with a passageway primarily for endoscopic procedures accessing the ureter through the bladder. The sheath has a bend limiting feature to limit the bend angle or bend radius. The sheath exhibits flexibility up to this limit at which point it becomes rigid. Excessive force is required to bend the sheath beyond the bend limit and would result in the kinking of the tubular frame.
