Abstract

An endoscopic surgical device for retrieving objects, such as for example, severed human tissue, foreign objects or impacted food bolus, from within a subject is disclosed. The device includes a body and handle movable relative to the body, a tubular member fixed to the body, a link having a first end fixed to the handle and a second end remote from the body, and a net including a loop and a net element. The loop is expandable and collapsible by action of the handle relative to the body. The loop retains an expanded configuration when deployed to allow for the capture certain objects that were otherwise difficult to capture because of positioning, location, or object characteristics. The loop may be constructed of flat wire and form a polygon shape when deployed. Structure at the distal end of the loop may propel and retain the loop into an open position when in use in narrow organs such as the esophagus.
