Abstract

An endoluminal stent has a core 1 such as stainless steel which has an expandable capability through the provision of slits which form interstices 1a after assisted or self-expansion following which the core is sufficiently rigid to support the vessel into which it is inserted. The core 1 is shown here in a partially expanded. The core 1 has an outer covering 2 of a material such as Dacron or PTFE which is coated on surface with an agent or agents such as collagen or gelatin, in order to decrease the material porosity and enhance incorporation into surrounding tissues. This coating in itself may be bonded with or incorporate a therapeutic agent or agents such as Heparin or an antibiotic. Internally the core 1 includes a lining 3 of a material similar to the outer covering layer and this may also be coated with an agent or agents such as collagen or gelatin, in order to decrease the material porosity and enhance incorporation into surrounding tissues. The outer covering and the lining are joined around the ends of the core. The stent thus provides smoothed blood flow as well as reducing re-stenosis due to muscle cell growth as well as offering a means for long term delivery of a therapeutic agent.
