Claims23
A device for repair of a ligament exposed to synovial fluid and connected to a first bone, the device comprising:
- a suture having a first end and a second end, the suture being attachable to a ruptured end of a ligament;
- a first mechanical device configured for attachment to the first bone and the suture such that the suture is threadable through the first mechanical device;
- and
- a porous hydrophilic scaffold comprising collagen and is capable of compression and expansion, the porous scaffold having a first end, a second end opposite the first end, a size, and a shape configured to be positionable adjacent to the ruptured end of the ligament, wherein the porous scaffold is threaded onto the suture and is configured to repair the ligament when positioned adjacent to the ruptured end of the ligament.

A device, comprising:
- a suture having a first end and a second end, the suture being attachable to a ruptured end of a tissue exposed to synovial fluid;
- an anchor configured for attachment to a first bone and the suture such that the suture is threaded through the anchor;
- and
- a porous hydrophilic scaffold comprising collagen and is capable of compression and expansion, the porous scaffold threaded onto the suture and having a size, and a shape configured to be positioned adjacent to a ruptured portion of the tissue to allow cell ingrowth into the porous scaffold to repair or regrow the tissue.
