Vascular prosthesis containing in the wall microcapsules, including hormone-producing cells

摘要

A vascular prosthesis having a low porosity outer material such as PTFE, and an inner synthetic tubular mesh. Semi-permeable microcapsules that contain hormone-producing cells, are placed between the outer material and the inner mesh. The microcapsules are preferably made of polysaccharides or amino-acid polymers.
