Abstract
A suture retention device is described. The suture retention device has various uses, one being for a gastropexy. A gastropexy may use a suture to hold the stomach against the abdominal wall of a patient. According to one example, a suture retention device is described that may have a shell having a thickness and an upper surface and a lower surface spaced apart by the thickness, the shell having an outer diameter that is greater than the thickness, the shell defining an internal chamber. A spring may be mounted within the internal chamber. The shell may be movable relative to a suture that passes through the shell and engages the spring.
Claims17
A suture retention device, comprising:
- a shell having a thickness and an upper surface and a lower surface spaced apart by the thickness, the shell having an outer diameter that is greater than the thickness, the shell defining an internal chamber, the lower surface having a suture entrance hole;
- a spring mounted within the internal chamber;
- a suture having in succession a first length of suture outside the shell and a reservoir length of suture within the internal chamber engaging the spring and a second length of suture outside the shell, the shell being movable relative to the second length of suture by deflecting the spring and reducing the reservoir length of suture;
- and,
- an anchor attached to the second length of suture;
- wherein the suture entrance hole is at the center of the lower surface with the second length of suture passing through the suture entrance hole and the shell has a suture exit hole with the first length of suture passing through the suture exit hole.
A method of retaining a suture with a suture retention device, the suture retention device comprising a shell having an upper surface, a lower surface, an internal chamber, a suture in succession having a first length of suture outside the shell and a reservoir length of suture within the internal chamber that engages a spring and a second length of suture outside the shell,
- the method comprising:
- locking the first length of suture to the shell;
- moving the shell relative to the second length of suture by deflecting the spring and reducing the reservoir length of suture;
- and
- unlocking the suture, repositioning the shell along the suture and re-locking the suture in the shell.
The suture retention method of clam 11, comprising resiliently moving the shell along the second length of suture.
