Abstract

The present disclosure is directed to methods, compositions, devices and kits which pertain to the attachment of stent-containing medical devices to tissue.

First claim

What is claimed is:

1. A medical device comprising:
(a) a stent component having two ends, a central region therebetween, and structural elements extending around a circumference of the stent component, wherein a plurality of adjacent structural elements of the structural elements are connected to define at least one cell therebetween;
(b) a coating or covering material disposed on the stent component; and
(c) a bonding material associated with a subset of the plurality of adjacent structural elements, a portion of the coating or covering material, or both;
wherein the bonding material does not span each cell between adjacent structural elements.

2. The medical device of claim 1 , wherein the coating or covering material covers only a portion of the stent component.

3. The medical device of claim 2 , wherein the bonding material is associated with the stent component in areas of the stent component not covered by the coating or covering material.

4. The medical device of claim 2 , wherein the ends of the stent component are not covered by the coating or covering material.

5. The medical device of claim 2 , wherein the coating or covering material is provided with a plurality of openings that provide areas where the stent component is not covered by the coating or covering material.

6. The medical device of claim 1 , wherein the bonding material is associated with the plurality of adjacent structural elements located at the ends of the medical device but not the center region of the medical device.

7. The medical device of claim 1 , wherein the bonding material is configured to bond to tissue when the bonding material is exposed to an energy source.

8. The medical device of claim 7 , wherein the energy source is selected from a light energy source, a microwave energy source, a radio frequency energy source, infrared energy source, radiation source, and a plasma energy source.

9. The medical device of claim 1 , wherein the medical device is self-expanding or balloon-expandable.

10. The medical device of claim 1 , wherein the bonding material is associated with the medical device by integrating the bonding material into at least a portion of the plurality of adjacent structural elements.

11. The medical device of claim 1 , wherein the coating or covering material comprises:
(a) polysiloxanes;
(b) fluoropolymers;
(c) polyamides;
(d) polyesters;
(e) polyurethanes;
(f) polyolefin polymers;
(g) polyoxyalkylenes; or
(h) styrenic copolymers; or
(i) any combinations one or more of the foregoing (a)-(h).

12. A method of treatment:
inserting a medical device having a stent component, the stent component comprising:
two ends, a coating or covering material disposed on the stent component, a bonding material, and structural elements extending around a circumference of the stent component;
wherein a plurality of adjacent structural elements of the structural elements are connected to define at least one cell therebetween;
wherein the bonding material is associated with a subset of the plurality of adjacent structural elements, a portion of the coating or covering material, or both; and
wherein the bonding material does not span each cell between the plurality of adjacent structural elements,

deploying the stent component in a body lumen such that the medical device contacts a tissue wall of the body lumen; and
bonding the bonding material to the tissue wall.

13. The method of claim 12 , wherein the bonding material is configured to bond to tissue when the bonding material is exposed to an energy source.

14. The method of claim 13 , wherein the energy source is selected from a light energy source, a microwave energy source, a radio frequency energy source, infrared energy source, radiation source, and a plasma energy source.

15. The method of claim 12 , wherein the medical device is deployed in the body lumen using a balloon catheter or a catheter having a retractable sheath.

16. The method of claim 12 , wherein the bonding material is applied independently of the medical device.

17. The method of claim 12 , wherein the bonding material is applied along with the medical device.

18. A medical device, comprising:
(a) a stent body with a plurality of structural elements extending around a circumference of the stent body, wherein one or more of the plurality of structural elements are connected to at least one adjacent of the plurality of structural elements to define one or more cells therebetween;
(b) a coating or covering disposed on the stent; and
(c) a bonding material disposed on the one or more of the plurality of structural elements connected to the at least one adjacent of the plurality of structural elements defining one or more cells, the coating or covering, or both, wherein the bonding material does not span the one or more cells.

19. The medical device of claim 18 , wherein the coating or covering material covers only a portion of the stent body.

20. The medical device of claim 19 , wherein the bonding material is associated with the stent body in areas of the stent body not covered by the coating or covering material.
