Patent ID: 7326244

Claim:
A composite wall structure for a vascular tubular member for repair of injury to a blood vessel within the body, said composite wall structure comprising; A. flexible stands and structural strands, said flexible strands having a different physical stiffness than said structural strands, some of said flexible strands having axial componency and being interwoven in an alternating manner over and under consecutive flexible strands having circumferential componency, said flexible strands providing for sealing at crossover points, B. at least some of said structural strands extending substantially in a circumferential direction forming circumferential structural strands, said circumferential structural strands being interwoven by said flexible strands wherein any one of said flexible strands having circumferential componency is replaced by one of said circumferential structural strands, said circumferential structural strands providing for anti-kinking characteristics for the vascular tubular member and said circumferential structural strands being exposed an equal portion to both the inside and outside of the tubular member, said circumferential structural and said flexible strands having substantially continuous contact with neighboring strands such that said composite wall structure will not significantly leak blood serum or blood cellular elements.
