摘要:
A stent is provided with a series of short pieces or sections connected together by a bioresorbable polymer. The stent sections are designed to separate or articulate with time as the polymer biodegrades. The time of separation can be controlled by the characteristics of the bioresorbable polymer to allow the stent to be buried in neo-intima. By using a tube made of a bioresorbable polymer, the continuous covering of the tubing may inhibit embolization in the first few weeks after stent implantation within the walls of a vessel and timing for removal of the tube through formulation of the bioresorbable polymer can be controlled to occur when embolization is no longer a risk. When the detachment of the stent pieces or sections occurs, they are fixedly secured within the vessel and each is able to flex with the vessel independently of the other stent segments.
