Assesment of Burst Strenght and Dilation in Vascular Grafts

Abstract

The p~lrpose of this st~ldy has been lo investigate the burst strength and dilative properlies of several types of vascular graft. B~ust strength and dilation can be counted among the nwst important mechanical characteristics of vascular grafi. In this st~ldy. the objective has been accomplished; by camjing out the burst strength measurements both in tubular form using devices clewloped in textile laboratories of University of Man~land and inlflat form employing AAMI [Association for the Advancement of Mediccd Insb-uments) test method VP20- 1986. by examining the creep behavior of tubrdar specimens under static loads.
