Abstract

A medical device assembly includes an implant having a support portion, and an arm portion and a dilator. The medical device assembly further includes a first suture having a first portion coupled to the arm portion of the implant, and a second portion coupled to the dilator. In addition, the assembly includes a second suture having a first portion coupled to the arm portion of the implant, and a second portion coupled to the dilator.

Claims

1. A medical device assembly, comprising:

an implant having a support portion and an arm portion;

a dilator;

a sleeve coupled to the dilator;

a first suture having a first portion coupled to the arm portion of the implant and a second portion coupled to the dilator, the first suture forming an outer loop along the arm portion and within the sleeve, the outer loop having a first strand and a second strand; and

a second suture having a first portion directly connected to the arm portion of the implant and a second portion directly connected to the dilator, the second suture forming an inner loop along the arm portion and within the sleeve, the inner loop being disposed between the first strand of the outer loop and the second strand of the outer loop.

2. The assembly of claim 1, wherein the sleeve defines a cavity, at least a portion of the arm portion of the implant being disposed within the cavity defined by the sleeve.

3. The assembly of claim 1,

wherein the sleeve defines a cavity, at least a portion of the arm portion of the implant being disposed within the cavity defined by the sleeve, at least a portion of the first suture being disposed within the cavity defined by the sleeve, at least a portion of the second suture being disposed within the cavity of the sleeve.

4. The assembly of claim 1, further comprising:

an association member coupled to the dilator, the association member being configured to associate the assembly to a delivery device.

5. The assembly of claim 1, wherein the first portion of the first suture is coupled to the arm portion of the implant at a first location on the arm portion, the first portion of the second suture is coupled to the arm portion of the implant at a second location on the arm portion different than the first location.

6. The assembly of claim 1, wherein the first portion of the first suture is coupled to the arm portion of the implant at a first location on the arm portion, the first portion of the second suture is coupled to the arm portion of the implant at a second location on the arm portion different than the first location, the first location being disposed between the second location and the support portion of the implant.

7. The assembly of claim 1, wherein a portion of the outer loop of the first suture is woven through a portion of the arm portion of the implant at a first location of the implant, and a portion of the inner loop of the second suture is woven through a portion of the arm portion of the implant at a second location of the implant.

8. The assembly of claim 1, wherein ends of the second suture are coupled to an interior wall of the dilator, and ends of the first suture are coupled to the interior wall of the dilator.

9. The assembly of claim 1, wherein at least a portion of the first suture is woven through a portion of the arm portion of the implant, at least a portion of the second suture is woven along a longitudinal axis of the arm portion of the implant.

10. The assembly of claim 1, wherein the arm portion of the implant is a first arm portion, the dilator is a first dilator, and the implant includes a second arm portion, the assembly further comprising:

a second dilator;

a third suture having a first portion coupled to the arm portion of the implant and a second portion coupled to the dilator; and

a fourth suture having a first portion coupled to the arm portion of the implant and a second portion coupled to the dilator.

11. A medical device assembly, comprising:

an implant having a support portion and an arm portion;

a dilator;

a sleeve coupled to the dilator;

a first suture having a first portion coupled to the arm portion of the implant and a second portion coupled to the dilator, the first suture forming an outer loop along the arm portion and within the sleeve, the outer loop having a first strand and a second strand; and

a second suture having a first portion directly connected to the arm portion of the implant and a second portion directly connected to the dilator, the second suture being woven through a portion of the sleeve and a portion of the arm portion of the implant, the second suture forming an inner loop along the arm portion and within the sleeve, the inner loop being disposed between the first strand of the outer loop and the second strand of the outer loop.

12. The assembly of claim 11, wherein the sleeve defines a cavity, at least a portion of the arm portion of the implant being disposed within the cavity defined by the sleeve.

13. The assembly of claim 11, wherein the sleeve defines a cavity, at least a portion of the arm portion of the implant being disposed within the cavity defined by the sleeve, at least a portion of the first suture being disposed within the cavity defined by the sleeve.

14. The assembly of claim 11, wherein a first end portion of the first suture is coupled to an interior wall of the dilator and a second end portion of the first suture is coupled to the interior wall of the dilator, the first suture looping back at a first location on the arm portion to form the outer loop, wherein a first end portion of the second suture is coupled to the interior wall of the dilator and a second end portion of the second suture is coupled to the interior wall of the dilator, the second suture looping back at a second location on the arm portion to form the inner loop.

15. The assembly of claim 11, wherein at least a portion of the first suture is woven through a portion of the arm portion of the implant.
