Resection device with support mechanism and related methods of use

A medical device for resecting tissue, the medical device comprising:

• an elongate member having a distal end, a proximal end, and a lumen extending therebetween, the elongate member having an opening at the distal end in communication with the lumen;
• a support structure having a slot in communication with the lumen of the elongate shaft, and a lumen formed therein;
• a snare loop having a first position secured within the slot of the support structure, and a second position disposed within the lumen of the elongate shaft;
• and
• an actuation member slidably disposed within the lumen of the elongate shaft, the actuation member includes a distal end secured to the snare loop;
• and
• a plurality of guide elements having proximal portions and distal portions, the proximal portions of the guide elements extending proximally through the lumen of the elongate shaft, and the distal portions connected to the snare loop.

A method for manipulating tissue comprising:

• introducing a medical device within a body cavity, the medical device including:
• an elongate shaft having a proximal end, a distal end, and a lumen extending therebetween, wherein the distal end of the elongate shaft includes an opening in communication with the lumen;
• a support structure having a slot extending along an inner surface of the support structure, the slot being in communication with the lumen of the elongate shaft;
• a snare loop having a first position secured within the slot of the support structure, and a second position disposed within the lumen of the elongate shaft;
• and
• an actuation member slidably disposed within the lumen, wherein the actuation member includes a distal end secured to the snare loop;
• advancing an introduction sheath to a desired location within the body cavity;
• extending the snare loop out of the elongate sheath;
• placing the snare loop over tissue targeted for resection;
• and
• manipulating the tissue with the medical device.
