Abstract
Systems and methods for creating autologous monocuspid and bicuspid valves can include a catheter having a single expandable element or a double expandable element. Once the leaflets of the valve are created, various techniques can be used to fix the leaflets to the vessel wall or to each other, including clips, tissue anchors, adhesives, and heat.
Claims14
A catheter system for forming a hydrodissection pouch within a vessel wall at a treatment site, wherein the catheter system comprises:
- a catheter including:
- a proximal end and a distal end, wherein the distal end includes a trough having support rails configured to contact vessel wall tissue at the treatment site;
- and
- a lumen extending from the proximal end to the distal end;
- and
- a dissection assembly configured to be slidably received within the lumen, wherein the dissection assembly includes:
- a puncture element having a beveled distal edge, wherein the puncture element is configured to be:
- advanced within the vessel wall, and
- fluidly coupled to a source of pressurized fluid and eject the pressurized fluid while being advanced within the vessel wall to form the hydrodissection pocket;
- a puncture element sheath configured to be advanced distally beyond the beveled edge of the puncture element while the puncture element ejects the pressurized fluid in the vessel wall such that the puncture element sheath shields the tissue of the vessel wall from the puncture element during formation of the hydrodissection pouch;
- and
- a dilator configured to be advanced within the lumen, wherein the dilator has a dilator lumen that is configured to slidably receive the puncture element sheath.
