Abstract

Novel endoprostheses comprising one or more photocurable materials are disclosed. Said endoprostheses may comprise regions wherein said photocurable materials are selectively disposed about said endoprosthesis and are cured according to desired parameters to achieve varying desired properties. Said properties may include but are not limited to cross-linking density, material density, modulus of elasticity, rate of erosion, extensibility, compressibility, mechanical strength, tensile strength, crystallinity, diffusion coefficient, and permeability.

Claims

1. A system for treating a stenosis in a body lumen, said system comprising:

an endoprosthesis comprising a first curable material and comprising a first region and a second region, wherein said first curable material is curable by exposure to a radiation source;

a radiation emitting catheter comprising an inflatable balloon, wherein said balloon comprises a photolithographic masking coating to prevent the exposure of said second region of said endoprosthesis to radiation.

2. The system of claim 1 wherein said photolithographic coating comprises a desired geometric pattern.

3. The system according to claim 1 wherein said endoprosthesis further comprises one or more endoprosthesis elements, and said endoprosthesis elements comprise a plurality of apices alternating with a plurality of straight sections.

4. The system according to claim 3 wherein said endoprosthesis further comprises one or more connecting members disposed between said one or more endoprosthesis elements.

5. The system according to claim 2 wherein said desired geometric pattern comprises a plurality of apices alternating with a plurality of straight sections.

6. The system according to claim 5 wherein said apices comprise peaks and valleys, and one or more of said peaks is disposed opposite one or more valleys, and said geometric pattern further comprises one or more straight sections connecting one or more of said peaks and valleys.

7. The system according to claim 4 wherein said endoprosthesis elements comprise a first degree of rigidity and said connecting members comprise a second degree of rigidity, wherein said first degree of rigidity is greater than said second degree of rigidity.

8. The system according to claim 1 wherein said endoprosthesis further comprises outer ends having a first degree of rigidity and a middle region, and said middle region comprises a second degree of rigidity, wherein said second degree of rigidity is greater than said first degree of rigidity.
