Sigmoid valve and method for its percutaneous implantation
A multi-leaflet valve adapted to serve as a prosthesis for diseased native valve of a mammal is incorporated in self-expandable or inflatable endovascular stents or stents to form a combination which is introduced on a catheter with a guide wire into the circulatory system of the mammal to replace the diseased native valve. Once the combination is at the desired location the stent is caused to expand and affix itself to the patient's vessel wall. The prosthetic valve has the shape of a truncated cone that has an inflow and an outflow orifice with leaflets forming the outflow orifice and forming a plurality of commissures. A first flexible circular support is affixed in a substantially circular fashion around the truncated cone in proximity of the inflow orifice, and a second flexible circular support is affixed at the location of the commissures to form a circle around the truncated cone in proximity of the outflow orifice. The circular supports maintain the shape of the valve during the surgical implantation procedure and thereafter.

Intravascular stent
An intravascular stent assembly for implantation in a body vessel, such as a coronary artery, includes undulating circumferential rings having peaks on the proximal end and valleys on the distal end. Adjacent rings are coupled together by links. The rings and links are arranged so that the stent has good conformability as it traverses through, or is deployed in, a tortuous body lumen. The stent is also configured such that the likelihood of peaks and valleys on adjacent rings which point directly at each other to overlap in tortuous body vessels is reduced.

Biodegradable endovascular stent using stereocomplexation of polymers
A biodegradable stent is comprised of a stereocomplex of polylactide enantiomers. The unique characteristics of stereocomplex polymers allows for the stent to have variable material characteristics along its length, while retaining uniform geometry. Thus, the stent is designed to be flexible upon insertion through the blood vessels while still retaining its rigidity and support upon expansion within the vessel. Furthermore, the material characteristics can be manipulated such that high strengths are possible even with small thicknesses of struts within the stent.
