Abstract

An electronic anti-coagulation stent structure is disclosed. The stent structure comprises a pair of coaxial metal stents having a layer of dielectric material between the stents. A battery is operatively connected preferably near or adjacent to the upstream end upon deployment of the stent. The positive battery terminal establishes an electrical connection to the outer metal stent and the negative terminal establishes an electrical connection to the inner metal stent and this exhibits a capacitor-like properties. The inner metal stent, being negatively charged, promotes a platelet repellent, anti-thrombotic effect.

Claims

1. A coaxial stent structure comprising:

a pair of coaxial stents;

a battery having its negative terminal operably connected to the inner stent and the positive terminal operably connected to the outer stent; and

,

insulation material positioned between said pair of coaxial stents sufficient to prevent conductivity.

2. The coaxial stent structure of claim 1 wherein each of said coaxial stents comprise a plurality of connected sinusoidal rings.

3. The coaxial stent structure of claim 1 wherein said insulation material is a layer of dielectric material.

4. The coaxial stent structure of claim 1 wherein said insulation material is an electret.

5. A coaxial stent structure for intra-arterial deployment in an arterial pathway to relieve arterial stenosis comprising:

a pair of coaxial stents, each stent comprising a plurality of sinusoidal rings connected by a plurality of stems;

a battery having its negative terminal operably connected to the inner stent and the positive terminal operably connected to the outer stent upon intra-arterial deployment; and

,

a layer of insulation material positioned between said pair of coaxial stents sufficient to prevent conductivity between said stents.

6. The coaxial stent structure of claim 5 wherein said insulation material is a layer of dielectric material.

7. The coaxial stent structure of claim 5 wherein said insulation material is an electret.

8. A coaxial stent structure for intra-arterial deployment comprising:

a pair of stents in coaxial relationship to one another and suitably sized for intra-arterial deployment;

a battery physically attached to at least one of said stents;

insulation material positioned between said pair of stents sufficient to prevent conductivity; and

,

where upon positioning said coaxial stent structure within an artery and said pair of stents are deployed, the negative terminal of said battery becomes operably connected to the inner stent and the positive terminal of said battery terminal becomes operably connected to the outer stent.

9. The coaxial stent structure of claim 8 wherein said insulation material is a layer of dielectric material.

10. The coaxial stent structure of claim 8 wherein said insulation material is an electret.

11. The coaxial stent structure of claim 8 where said battery is attached to one of said stents near or adjacent to the upstream end of said stent.
