MINIMALLY INVASIVE NO TOUCH (MINT) PROCEDURE FOR HARVESTING THE GREAT SAPHENOUS VEIN (GSV), ENDOSCOPIC ASVAL TECHNIQUE AND ASSISTED PIN STRIPPING OF SUPERFICIAL GSV, HYDRODISSECTION-BASED ENDOSCOPIC VEIN HARVESTING (EVH) SYSTEM, VENOUS HYDRODISSECTOR, RETRACTOR AND TIP ADAPTER FOR USE WITH FLEXIBLE CYSTOSOPE AND ADAPTED CYSTOSCOPE SYSTEM

A method of atraumatically hydrodissecting and maintaining endothelial function and structure of a vascular target includes forming an incision in tissue proximate one end to realize an insertion space, inserting a distal end of a cannula and/or endoscope into the insertion space and while visualizing the vascular target, ejecting a hydrodissecting fluid from the distal end of the cannula and/or endoscope to substantially separate or dissect the vascular target from the surrounding tissue, while advancing the distal end through the space as it is enlarged by the hydrodissecting fluid, to a distal target end of the vascular target. The hydrodissecting fluid is formulated to minimize or prevent formation of microthrombi in the hydrodissected vascular target. The hydrodissecting fluid is a water-based vascular graft treatment solution and can include any of a balance salt solution, a metallic salt solution, such as Plasma-Lyte® A, a vascular graft treatment solution, such as Duragraft® solution, L-Arginine, aspirin and low molecular weight heparin.
