Releasable elongated assembly
A releasable elongated assembly includes a release member having a length and an opening that extends along the length. The releasable elongated assembly includes a first elongated element having a first coupling member disposed in the opening and a second elongated element having a second coupling member disposed in the opening opposite the first coupling member along the length. The first and second elongated elements are interlaced with each other in the opening at a location between the first coupling member and the second coupling member such that the first and second elongated elements are attached to each other. The release member is moveable from a first position where the first and second coupling members are captured in the opening to a second position where the first and second coupling members are released from the opening so as to detach the first and second elongated elements from each other.
1. A suture assembly elongate along a longitudinal direction, the suture assembly, comprising:
a release member including a lumen that extends along the longitudinal direction; a first suture having a first coupling member disposed in the lumen;
a second suture having a second coupling member disposed in the lumen opposite with respect to the first coupling member along the longitudinal direction; and
a releasable joint where the first suture and the second suture are interlaced with each other in the lumen, the releasable joint being disposed between the first coupling member and the second coupling member along the longitudinal direction,
and the suture assembly is configured to transition from 1) a first attached configuration where the release member captures the first coupling member, the releasable joint, and the second coupling member so as to prevent release of the first and second sutures from each other, into 2) a second released configuration where the release member is moved along the longitudinal direction to release the first and second sutures from each other; and
wherein the first suture is folded in the lumen to define a first loop adjacent to the first coupling member, and the second suture is folded in the lumen to define a second loop that is interlaced with the first loop to define the releasable joint; and
wherein the first attached configuration is where the release member inhibits a) travel of the first coupling member through the second loop and b) travel of the second coupling member through the first loop, thereby capturing the first coupling member, the releasable joint, and the second coupling member.
2. The suture assembly of claim 1 , wherein the release member includes an inner surface that defines the lumen, the inner surface further defining a lumen cross-sectional dimension that is perpendicular to the longitudinal direction, and the lumen cross-sectional dimension is sized such that the first and second coupling members are inhibited from moving past each other in the lumen.
3. The suture assembly of claim 1 , wherein the release member includes a first end and a second end opposite the first end along the longitudinal direction, and the lumen extends from the first end to the second end.
4. The suture assembly of claim 1 , wherein the first suture extends out of the first end of the release member and is attached to an instrument, and the second suture extends out of the second end of the release member and is attached to an implant configured to be implanted into tissue.
5. The suture assembly of claim 1 , wherein either the first suture or the second suture is attached to a closure device configured to seal a puncture in a vessel.
6. The suture assembly of claim 1 , wherein either the first suture or the second suture is attached to a needle configured to guide the respective suture through tissue.
7. The suture assembly of claim 1 , wherein the first suture includes a first elongate portion, and a second elongate portion, and the first and second elongate portions each extend in a direction away from the releasable joint out of the release member.
8. The suture assembly of claim 1 , wherein the first and second coupling members are first and second knots.
9. The suture assembly of claim 8 , wherein the first and second knots are defined by, and monolithic with, the respective first and second sutures.
10. The suture assembly of claim 8 , wherein the first and second knots are formed from separate materials such that the first and second knots are separate from and attached to the first and second sutures.
11. The suture assembly of claim 1 , wherein the first and second coupling members are first and second bodies coupled to the respective first and second sutures.
12. The suture assembly of claim 11 , wherein each coupling body has a cross-sectional shape that corresponds to a cross-sectional shape of the lumen.
13. The suture assembly of claim 11 , wherein each suture is elongate along a respective central axis, and each coupling body has a cross-sectional dimension that is perpendicular to the respective central axis and is greater than a cross-sectional dimension of the respective suture, wherein the cross-sectional dimension of the respective suture is perpendicular to the respective central axis.
14. The suture assembly of claim 1 , wherein each suture is a multifilament suture, a monofilament suture, or a braided suture.
15. The suture assembly of claim 1 , each suture has a United States Pharmacopeia size between #11-0 to #7.
