Abstract
A system for creating an endoluminal valve from a blood vessel wall, includes: a tubular assembly having a longitudinal axis, a proximal end, a distal portion with a distal end, and a first lumen extending from the proximal end to a distal port located proximate the distal portion, the distal port located along the longitudinal axis, the distal portion having a supporting surface on a same side of the tubular assembly as the distal port, the supporting surface extending in a longitudinal direction and offset from a surface of the tubular assembly proximal the distal port and configured to contact the blood vessel wall; and a tissue dissection probe disposed within the first lumen, the tissue dissection probe having a fluid delivery lumen extending to a fluid delivery port located at a distal end of the tissue dissection probe, the tissue dissection probe configured to be inserted into the blood vessel wall.
