Abstract
According to one aspect, a medical device may include a luminal element configured for insertion into a natural body lumen. The medical device may further include a tool configured to be received within the luminal element. The tool may include a plurality of operating members. Each of the operating members may include an elongate member and a cutting member. The cutting member may be located at a distal end of the elongate member. Further, the cutting member of a first operating member of the plurality of operating members may be rotatable with respect to the cutting member of a second operating member of the plurality of operating members.
Claims20
A medical device, comprising:
- a luminal element;
- a tool movably received within the luminal element, the tool including a plurality of operating members, each of the operating members including a shaft and a cutting member, the cutting member being located at a distal end of the shaft;
- wherein the cutting member of a first operating member of the plurality of operating members is rotatable with respect to the cutting member of a second operating member of the plurality of operating members;
- and
- a multi-lumen retention clip positioned at a distal end of the luminal element.
A method of extracting tissue, comprising:
- advancing a luminal element into a natural body lumen;
- advancing a tool through the luminal element, the tool including a plurality of operating members, each of the operating members including a shaft and a cutting member;
- surrounding target tissue within the cutting members of each of the operating members;
- rotating the cutting member of a first operating member of the plurality of operating members relative to the cutting member of a second operating member of the plurality of operating members to trap the surrounded target tissue while rotating the shaft of the first operating member relative to a c-shaped lumen of a retention clip;
- and
- retracting the cutting members of the first and second operating members into the luminal element so as to cut the target tissue.
A method of extracting tissue, comprising:
- advancing a luminal element into a natural body lumen;
- advancing a tool through the luminal element, the tool including a plurality of independently actuatable operating members, each of the operating members including a shaft and a cutting member, the cutting member being located at a distal end of the shaft, and each shaft extending through a c-shaped lumen of a retention clip;
- surrounding target tissue within the cutting members of each of the operating members;
- and
- rotating the cutting member of a first operating member of the plurality of operating members relative to the cutting member of a second operating member of the plurality of operating members to trap the surrounded target tissue while rotating the shaft of the first operating member relative to a c-shaped lumen of a retention clip positioned at a distal end of the luminal element.
