1. An inflatable vascular prosthesis comprising:
- an elongate tube having a proximal and a distal end, an outer diameter, a lumen extending from the proximal end to the distal end, said lumen closing at said distal end, wherein at least a part of said elongate tube adjacent the distal end is wound into a helix to form an inflatable tip having a secondary lumen within the helix, where the helix is maintained in a helically wound configuration with polymeric tie strips helically wound about the inflatable tip and which adhere to the helix and where said helix has a deflated outside diameter and a larger inflated outside diameter and where the helix is both inflatable and deflatable.
