## Abstract

A graft includes a flexible, resilient, generally tubular external support and a blood vessel segment, carried within and having an ablumenal surface in contact with and supported by the tubular support, the graft being capable of resilient radial expansion in a manner mimicking the radial compliance properties of an artery.

## Claims

### Claim 1

A graft for replacement of a section of an artery, the graft comprising a flexible, resilient, knit wire mesh configured as a generally tubular external support and a replacement blood vessel segment carried within and having an ablumenal surface in contact with and supported by the tubular support, the support having resilient radial expansion and contraction characteristics that provide the graft with compliance properties mimicking those of an artery.
