2010 Revamping the Polyp Snare
Team Members: Salar Assadian, Rose K. Leu, Brian K. Dang
Capstone Client: Ma Somsouk, M.D, Assistant Professor at UCSF, Medicine/Gastroenterology
Purpose/Goal:
Current polypectomy snares employed to desiccate polyp tissue are often entrapped in the polyp tissue, making retraction of the snare difficult. To reduce snare entrapment during polypectomy, this project introduced a new snare design to reduce snare entrapment in cases of pedunculated polyps (i.e., a poly that is attached to the surface by a narrow elongated stalk). An important polyp type, as entrapment in pedunculated polyps leads to hemorrhaging and may require surgical intervention.
