| Popis: | Biodegradable, shape-memory polymers, which have ability to recover previously defined shape under the influence of an external stimulus opens up new perspectives for designing vascular implants, especially such as stents, and methods of their implantation [Yakacki, 2006]. Nevertheless, introduction of biodegradable stent, whose function must be maintained in the environment of the vascular system, under the conditions of constant blood flow and elevated temperature, requires knowledge of the structural material properties and its changes at various stages of degradation. The aim of the presented work was to prepare new biodegradable polymer blends for vascular stents, induce and measure their thermal shape memory, investigate their biocompatibility in vitro and dynamics of in vitro biodegradation. |
