Abstract:
A ligating device adapted to be movably received on an insertion portion of the distal end of an endoscope, the ligating device comprising:a seal adapted to be affixed to the distal end of the endoscope; and a dispensing device for supporting at least one ligating band and having a proximal end adapted to receive the insertion portion of the endoscope, a distal end, and an interior surface; wherein, when in an operative position with respect to the endoscope, the interior surface at least partially encompasses a portion of the insertion portion of the endoscope and at least a portion of the seal, wherein the dispensing device is capable of movement from a retracted position to at least a dispensing position, where for the dispensing position the distal end of the dispensing device is spaced from the distal end of the endoscope, creating a volume substantially defined by the dispensing device, sufficient to perform a ligation procedure, and in the retracted position the volume is reduced relative to the volume at the dispensing position, and wherein the seal is adapted to establish a sealing relationship between the endoscope and the dispensing device during a ligation procedure.
