ABSTRACT:
A method of collecting a tissue portion at an obstructed site within anatomical tissue comprising the steps of inserting a distal end of a guide member in the anatomical tissue to position the distal end of the guide member at an obstructed site adjacent a tissue portion to be collected, visualizing the obstructed site remotely with an endoscope, injecting a viscous, optically clear fluidic material through the guide member for release at the obstructed site to displace the anatomical tissue and create a fluid filled space in the anatomical tissue adjacent the tissue portion, introducing a distal end of a tissue collector in the space, dissecting the tissue portion from the anatomical tissue with the distal end of the tissue collector and removing the tissue portion from the anatomical tissue.
