PLATFORM FOR OPEN- LOOP POLYPECTOMY SYSTEM (16067)

Detailed Technology Description: None

*Abstract

Platform for Open-Loop Polypectomy System

Featuresand Benefits

May reduce risk of bleeding which can prolongsurgery and may require transfusion or surgery
May reduce the risk of a stuck snare which wouldrequire a second snare or surgery to remove the stuck snare
Allows for all sizes of polyps to be removed
No more need for “piecemeal polypectomy”

*This Technology is available for licensing, further development, or industrial partnering*

Market Opportunities

Currentmethods of polyp removal cannot handle very large polyps which present in about30% of cases. Even if polypectomy is attempted there is a significant chancethat acute bleeding may occur that could require transfusion or even surgery.If neither of these are needed, it can prolong the surgery as the cavity mustbe drained of blood and wound repaired to restore visualization of the polyp.Another uncommon risk associated with the removal of large polyps is a stucksnare, where a second snare or surgery to remove the first may be required. ThePOLP method should greatly increase the efficiency of polypectomy as itrequires less time and fewer instruments, as well as reduce the risk ofbleeding and almost completely removal the possibility of a stuck snare.

Technology

The Platform for Open-LoopPolypectomy (POLP) system utilizes a memory shape wire(s) passed around thestalk of the polyp which is then captured by the snare device. As the snarewire is retracted, the stalk of the polyp is severed and the polyp can beremoved. The snare device can easily be placed through and endoscopic tube withan instrument insertion channel. The POLP system can be used on any size polypand removes the need for “piecemeal polypectomy” for large, pedunculatedpolyps. While this technology is primarily for polyps in the colon, it can beadapted to remove polyps in the upper airway as well.
