Abstract
Tissue ligation systems and methods are provides to mechanically strangulate abnormal or undesirable tissue. Tissue ligation systems include a multi-lumen catheter having an outer diameter smaller than the inner diameter of a standard endoscope channel such that the catheter can be inserted into the endoscope. Tissue ligation systems also include a ligation apparatus with an expandable hood disposed at the distal end of the catheter. A suture extends through a lumen of the catheter and has a distal loop portion that can strangulate tissue.
