Estimating the term…
An apparatus for tissue dissection and instrument anchoring, including a dissection balloon having a viewing window (preferably a rigid, transparent window) at its distal end, or including an anchoring or dissection balloon having nonuniform elasticity selected to achieve desired inflated shape and pressure characteristics, and methods for using such apparatus. The window, which can be a lens, is transparent and either rigid or non-rigid but sufficiently strong to retain a desired optical shape while being pushed against tissue layers by a rigid instrument deployed within the balloon. In preferred embodiments, the balloon is a long-necked dissection balloon deployed through a cannula. In other embodiments, the invention is a dissection balloon assembly including a long-necked dissection balloon having a viewing window at its distal end, and a housing to which the dissection balloon's mouth is attached. In use, the distal end of a long-necked dissection balloon is inserted between tissue layers and inflated to dissect the tissue layers.

A device for dissection of tissue layers and instrument anchoring, including:
The device of claim 22, wherein the lateral end portions and the central portion are portions of a single piece of material, but said material has greater thickness at the central portion than at the lateral end portions.
A device for dissection of tissue layers and instrument anchoring, including:
A method for dissecting tissue layers and anchoring an object between dissected tissue layers, using an apparatus including a dissection assembly and an anchoring assembly, said dissection assembly including a housing and a dissection balloon having a mouth and a distal end, wherein the mouth is attached to the housing and a viewing window is provided at the distal end, said anchoring assembly including a cannula and an anchor balloon attached to the cannula, wherein the dissection balloon is initially deployed through the cannula, and wherein a rigid instrument having a distal tip and is initially deployed through the housing and the cannula so that the distal tip is within the dissection balloon, said method including the steps of:
A method for dissecting tissue layers and anchoring an object between dissected tissue layers, using an apparatus including a dissection assembly and an anchoring assembly, said dissection assembly including a housing and a dissection balloon having a mouth and a remaining portion, wherein the mouth is attached to the housing and the remaining portion has nonuniform elasticity selected to achieve desired inflated shape and pressure characteristics when the remaining portion is inserted between two tissue layers and inflated to dissect said tissue layers, said anchoring assembly including a cannula and an anchor balloon attached to the cannula, wherein the dissection balloon is initially deployed through the cannula, and wherein a rigid instrument having a distal tip is initially deployed through the housing and the cannula so that the distal tip is within the dissection balloon, said method including the steps of:
