Appl. No.:

16/359860

Inventors:

- Needham MA, US
Joseph Siletto - Needham MA, US
Gary R. McCarthy - East Bridgewater MA, US
James Angelo Libby - Kingston MA, US
Daniel J. Borsari - Halifax MA, US
Danial Ferreira - Woodbridge CT, US

International Classification:

A61B 17/42
A61B 10/06
A61B 10/02
A61B 10/04
A61B 17/32

Abstract:

A polyp removal device comprises an outer tubular body; an inner tubular body; a tubular cutter coupled to or formed as part of the distal end of the inner tubular body; a spring positioned to bias the inner tubular body in an extended direction with respect to the outer tubular body; a handle coupled to the proximal end of the outer tubular body; an actuation member movably coupled to the handle; and a disconnect mechanism for selectively coupling the actuation member to the inner tubular body and decoupling the actuation member from the inner tubular body, the disconnect mechanism is configured to automatically decouple the inner tubular body from the actuation member when the actuation member is moved in a first direction for a distance greater than a predetermined distance.

Appl. No.:

15/616148

Inventors:

- Newton MA, US
Joseph Siletto - Needham MA, US
Gary R. McCarthy - East Bridgewater MA, US
James Angelo Libby - Kingston MA, US

International Classification:

A61B 17/42
A61B 17/32
A61B 17/00
A61B 17/22
A61B 17/295
A61B 17/3205

Abstract:

A polyp removal device comprises an outer tubular body; an inner tubular body being movable with respect to the outer tubular body; a handle; an actuation member configured to cause movement of the inner tubular body with respect to the outer tubular body when the actuation member is moved with respect to the handle; a vacuum port for coupling thereto of a vacuum source; and an opening near a distal end of the polyp removal device, the opening configured to allow fluid communication between an environment external to the polyp removal device and the lumen of the inner tubular body, wherein a size of the opening is variable based on the movement of the inner tubular body with respect to the outer tubular body.
