Endoscopic snare device

A tissue removal tool for use with an endoscope, the tissue removal tool comprising:

• a body;
• a conduit attached to the body, the conduit defining an inner lumen, wherein the inner lumen has a proximal portion having a first width and a distal portion having a second width that is greater than the first width;
• a loop that is movable between an open position in which the loop is at least partially disposed outside of the conduit and a closed position in which the loop is disposed within the conduit;
• and
• a transmitting assembly comprising a handle and a link, wherein the handle is connected to the body, wherein the link has a first end attached to the handle and a second end attached to the loop such that movement of the handle causes the loop to move between the open and closed positions.

A tissue removal tool for use with an endoscope, the tissue removal tool comprising:

• a body;
• a conduit attached to the body, the conduit defining an inner lumen, the inner lumen having a proximal portion having a first width and a chamfered distal end having a width that gradually increases along a length of the chamfered distal end from an initial width to a second width, wherein the first width of the proximal portion is between about 0.05 inches and 0.06 inches, wherein the length of the chamfered distal end is between about 0.015 inches and 0.06 inches, and wherein the second width of the chamfered distal end is between about 0.06 inches and 0.075 inches;
• a loop that is movable between an open position in which the loop is at least partially disposed outside of the conduit and a closed position in which the loop is disposed within the conduit;
• and
• a transmitting assembly comprising a handle and a link, wherein the handle is connected to the body, wherein the link has a first end attached to the handle and a second end attached to the loop such that movement of the handle causes the loop to move between the open and closed positions.
