Abstract
The pull-through appliance is made of a mesh structure formed of at least one continuous thread and a pullout thread disposed at one end of the mesh structure to prevent unraveling of the mesh structure. A hollow tube is used to facilitate drawing in of the synthetic strand and autologous strand of the prosthesis. After removal of the hollow member, the resulting package can be readily threaded through a bore in a bone. After implantation, the pull-out thread is removed and the mesh structure unraveled so as to remove the mesh structure from within the bone.
Claims9
A pull-through appliance for pulling through a bore in a bone comprising
- a tubular textile mesh structure for receiving at least one of a synthetic tendon prosthesis, a synthethic ligament prosthesis and at least one of an organic ligament prosthesis and an organic tendon prosthesis, said mesh being formed of at least one continuous thread having a free end extending therefrom;
- and
- a pull-out thread disposed at one end of said mesh structure to prevent unraveling of said mesh structure, said pull-out thread having a pair of free ends extending from said mesh structure.
A method of drawing a multistrand prosthesis through a bone comprising the steps of
- providing a tubular textile mesh structure formed of at least one continuous thread and a pull-out thread at one end of the mesh structure;
- positioning a hollow member within the mesh structure;
- drawing at least one of an organic tendon prosthesis and an organic ligament prosthesis, and one of a synthetic ligament prosthesis and a synthetic tendon prosthesis through the hollow member;
- thereafter removing the hollow member from within the mesh structure;
- passing the mesh structure and two prostheses through a bore in a bone;
- thereafter pulling the pull-out thread from the mesh structure;
- and
- pulling a free end of the thread of the mesh structure to unravel the mesh structure through the bore in the bone while leaving the two prostheses in the bore.
In a pull-through appliance for pulling through a bore in a bone, the combination comprising
- a tubular textile mesh structure formed of at least one continuous thread;
- a pull-out thread disposed at one end of said mesh structure to prevent unraveling of said mesh structure;
- at least one organic prosthesis extending through said mesh structure;
- and
- at least one synthetic prosthesis extending through said mesh structure.
