Abstract
A device configured to facilitate resection of tissue. The device may include a proximal end configured to be secured to a distal portion of an introduction sheath and a distal end defining an opening that may communicate with a channel extending between the proximal and distal ends. The opening may be defined by at least one straight edge.
Claims20
A resection device comprising:
- an elongate member having a proximal end, a distal end, and a longitudinal axis between the proximal end and the distal end;
- a cap at the distal end of the elongate member, wherein the cap includes an opening in communication with a channel extending between the proximal and distal ends of the elongate member;
- and
- a flexible portion between the proximal end of the elongate member and the opening, wherein an angle between the longitudinal axis of the elongate member and a plane of the opening is changeable, the opening is moveable about the flexible portion, and the opening includes at least one straight edge, wherein, when the flexible portion is in an unbent position, the opening faces to a side of the device and distal of the device.

A device comprising:
- an elongate member having a proximal end, a distal end, a channel extending between the proximal end and the distal end, a distal portion, an intermediate portion proximal to the distal portion and with flexibility greater than a flexibility of the distal portion, and a proximal portion proximal to the intermediate portion,
- wherein the distal portion of the elongate member includes an opening adapted to be placed proximate tissue, wherein the opening includes at least one straight edge, and wherein the opening is disposed in a plane that is angled relative to a longitudinal axis of the device, and the opening moves relative to the proximal portion of the elongate member about the intermediate portion, wherein, when the intermediate portion is in an unbent position, the opening faces to a side of the device and distal of the device.
A method for resecting tissue from a body, the method comprising:
- inserting a device into a body cavity, the device including:
- an elongate member having a proximal portion, a distal end, and a channel extending therebetween,
- a cap at the distal end of the elongate member, wherein the cap includes a distal end opening, wherein the distal end opening includes at least one straight edge, and
- a flexible portion between the proximal portion of the elongate member and the opening, wherein the distal end opening is angled relative to a longitudinal axis of the elongate member and is moveable relative to a longitudinal axis of the elongate member about the flexible portion, wherein, when the flexible portion is in an unbent position, the distal end opening faces a side of the device and distal of the device;
- and
- a cutting device configured to cut tissue, the cutting device being adapted for placement adjacent a distalmost edge of the distal end;
- pulling the tissue into the distal end opening;
- and
- resecting the tissue with the cutting device.
