Abstract
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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
94 words
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.
Claim 2
Dependent Claim
94 words
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.
Claim 3
Dependent Claim
16 words
An appliance as set forth in claim 1 wherein said mesh structure is a knitted fabric.
Claim 4
Dependent Claim
22 words
An appliance as set forth in claim 1 which further comprises a sterilizable dimensionally stable hollow member receiving said mesh structure thereon.
Claim 5
Independent Claim
139 words
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.
Claim 6
Independent Claim
139 words
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.
Claim 7
Dependent Claim
66 words
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.
Claim 8
Dependent Claim
66 words
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.
Claim 9
Dependent Claim
16 words
The combination as set forth in claim 5 wherein said mesh structure is a knitted fabric.
Claim 10
Dependent Claim
26 words
The combination as set forth in claim 5 which further comprises a sterilizable dimensionally stable hollow member receiving said mesh structure thereon and said prostheses therein.
Claim 11
Dependent Claim
22 words
The combination as set forth in claim 5 wherein said organic prosthesis is one of a ligament prosthesis and a tendon prosthesis.
Claim 12
Dependent Claim
22 words
The combination as set forth in claim 8 wherein said synthetic prosthesis is one of a ligament prosthesis and a tendon prosthesis.
