Movement prevention stent

Abstract

A system for implanting a stent in a body lumen may include an elongate tubular member having a lumen extending therethrough, a stent configured to transition from a delivery configuration to a deployed configuration, and an adhesive structure configured to secure the stent to the body lumen in the deployed configuration. The stent may be disposed within the lumen of the elongate tubular member in the delivery configuration. The adhesive structure may be disposed within the lumen of the elongate tubular member adjacent to the stent in a substantially inactive state. The adhesive structure may be configured to adhere to the stent and the body lumen after the stent and adhesive structure are deployed from the lumen of the elongate tubular member into the body lumen.

Claims

1. A system for implanting stents into body tubules, An elongated tubular member having a lumen extending within it, A stent configured to transition from a delivery configuration to a deployment configuration, An adhesive structure configured to fix the stent in the body lumen in the aforementioned deployment configuration, Equipped with, The stent is positioned within the lumen of the elongated tubular member in the delivery configuration. The adhesive structure is positioned in a substantially inert state adjacent to the stent and within the lumen of the elongated tubular member. The adhesive structure is not fixed to the stent within the lumen of the elongated tubular member. The adhesive structure is configured to adhere to the stent and the body lumen after the stent and the adhesive structure have been deployed from the lumen of the elongated tubular member into the body lumen. system.

2. The system according to claim 1, wherein the adhesive structure includes an adhesive element that is activated when deployed within the body lumen.

3. The system according to claim 2, wherein the adhesive element is pressure-sensitive.

4. The system according to claim 1, wherein the adhesive structure is positioned radially outward of the stent within the lumen of the elongated tubular member.

5. The system according to claim 1, wherein after the stent and the adhesive structure are deployed in the body lumen, a radially outward force is applied to the adhesive structure and the body lumen.

6. The system according to claim 5, wherein the radially outward force strengthens the adhesion between the stent and the adhesive structure, and between the adhesive structure and the body lumen.

7. The system according to claim 1, wherein the adhesive structure extends circumferentially around most of the circumference of the stent in the delivery configuration.

8. The system according to claim 1, wherein in the substantially inert state, the adhesive structure has a thickness between about 0.254 mm and about 2.032 mm.

9. The system according to claim 1, wherein the adhesive structure is positioned radially inward of the stent within the lumen of the elongated tubular member.

10. The system according to claim 9, wherein the adhesive structure is configured to adhere to the inner surface of the stent after the stent and the adhesive structure are deployed from the lumen of the elongated tubular member into the body lumen, and the adhesive structure is configured to adhere to the body lumen through a gap formed in the stent.

11. The system according to claim 1, wherein the adhesive structure includes a crosslinked polymer.

12. The system according to any one of claims 1 to 11, wherein the adhesive structure includes a plurality of woven fibers defining a patch.

13. The system according to claim 9 or 10, wherein the adhesive structure extends longitudinally beyond at least one end of the stent.

14. The system according to any one of claims 1 to 11, wherein the adhesive structure includes a longitudinal gap, the longitudinal gap allowing a fluid to reach the distal end of the adhesive structure while the stent and the adhesive structure are confined within the lumen of the elongated tubular member.

15. A system for implanting stents into body tubules, An elongated tubular member having a lumen extending within it, A stent configured to transition from a delivery configuration to a deployment configuration, An adhesive structure configured to fix the stent in the body lumen in the aforementioned deployment configuration, the adhesive structure includes a longitudinal gap extending along the length of the adhesive structure, Equipped with, The stent is positioned within the lumen of the elongated tubular member in the delivery configuration. The adhesive structure is positioned in a substantially inert state adjacent to the stent and within the lumen of the elongated tubular member. The adhesive structure is not fixed to the stent within the lumen of the elongated tubular member. The adhesive structure is configured to adhere to the stent and the body lumen after the stent and the adhesive structure have been deployed from the lumen of the elongated tubular member into the body lumen. system.

16. The system according to claim 15, wherein the adhesive structure includes an adhesive element that is activated when deployed within the body lumen.

17. The system according to claim 16, wherein the adhesive element is pressure-sensitive.

18. The system according to claim 15, wherein the adhesive structure extends circumferentially around most of the circumference of the stent in the delivery configuration.

19. The system according to claim 15, wherein the adhesive structure includes a plurality of woven fibers defining the patch.
