Abstract:
A stent for bloodvessel anastomosis, with a slippery, soft out layer and a rapidly soluble inner layer, is developed in this paper. The out layer is made up of the gelatin with a high purity and a low molecular weight, and the inner one of polyglycol with a molecular weight of 20000. The structure changes of the stent surface are studied with anastomosis environment simulated. The result proves that the stent can be applied to bloodvessel anastomosis
