Title:
HYBRID STENT
Document Type and Number:
WIPO Patent Application WO2005118971
Kind Code:
A3
Abstract:
A stent (30) is provided with a series of short pieces (34) or sections connected together by a bioresorbable polymer (36). 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 (32) 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 are able to flex with the vessel independently of the other stent segments.
