摘要:
A stent having an elongate tubular configuration is formed of a plurality of elongate elements interwoven or braided to form a tubular configuration. The elements may be relatively strong and rigid, but movable relative to each other within the weave or braid in order to provide the stent with generally soft characteristics. The elements may be formed of different materials, such as an absorbent material permitting the stent to be doped with materials such as drugs and chemicals. Even the absorbency can be controlled and varied to provide a predetermined time-release of the absorbent.
