Abstract

The present disclosure describes an assembly comprising an expandable device, a restraining member wrapped circumferentially around the device, a coupling member releasably securing the restraining member, and at least one tactile indicator located on the assembly at a desired point of partial deployment, along with a method for partially deploying the expandable device in a patient. During partial deployment of the expandable device, the coupling member is tensioned and displaced from outside the patient by a clinician, and upon reaching the tactile indicator, a change in tension on the coupling member is felt my the clinician performing the procedure.

Claims

1. An assembly comprising:

an expandable device;

a restraining member wrapped circumferentially around said device and having opposing edges;

an elongated coupling member releasably coupling the opposing edges of the restraining member into a releasable seam; and

at least one tactile indicator located on the assembly at a desired point of partial deployment of said device.

2. The assembly of claim 1, wherein said tactile indicator comprises a slack loop configured in said elongated coupling member.

3. The assembly of claim 1, wherein said tactile indicator comprises a disengaged portion further comprising a slack loop interwoven with said elongated coupling member.

4. The assembly of claim 1, wherein said device comprises an endoluminal prosthesis.

5. The assembly of claim 1, wherein said device is at least one of a graft, a stent, or a stent-graft.

6. The assembly of claim 1, wherein said device is self-expandable.

7. The assembly of claim 1, wherein said device is balloon expandable.

8. The assembly of claim 1, comprising more than one expandable device.

9. The assembly of claim 1, comprising more than one restraining member.

10. The assembly of claim 9, wherein the at least one tactile indicator is located on the assembly between any two adjacent restraining members.

11. The assembly of claim 1, wherein said partial deployment comprises a target portion.

12. The assembly of claim 11, wherein said target portion comprises a side branch fenestration on a surface of said device.

13. A method for partially deploying a device in a patient comprising:

positioning an assembly in the patient, said assembly comprising;

an expandable device;

a restraining member wrapped around the device and having opposing edges; and

, an elongated coupling member releasably coupling the opposing edges of the restraining member into a releasable seam; and

partially releasing said restraining member by tensioning and displacing said elongated coupling member from a position outside the patient, indicating a change in tension of said elongated coupling member.

14. The method of claim 13, wherein said elongated coupling member comprises a slackened loop.

15. The method of claim 13, further comprising sensing a lack of resistance in said elongated coupling member which coincides with reaching a slack loop in said elongated coupling member during displacement.

16. The method of claim 15, wherein the sensing of a lack of resistance during said partial deployment is felt by a clinician performing the partial deployment of said device.

17. The method of claim 13, wherein said device is at least one of a graft, a stent, or a stent-graft.

18. The method of claim 13, wherein said elongated coupling member comprises a disengaged portion further comprising a slack loop interwoven with said elongated coupling member.

19. The method of claim 13, wherein said device is self-expandable.

20. The method of claim 13, wherein said partial deployment comprises a target portion on said device.

21. The method of claim 20, wherein said target portion comprises a side branch fenestration on a surface of said device.
