Abstract
Abstract An object is attached to a bone by using blind rivets. The blind rivets can be set from the outside of the bone. Each blind rivet has a body, with a head on one end, and a mandrel extending from the head end of the body. A hole is formed in the bone. The rivet is inserted through the object and into the bone through a hole in the bone cortex. The rivet is set by pulling on the mandrel with the rivet gun. The rivet secures the object to the proximal cortex layer of the bone. The method is used to attach objects such as plates and hip sockets to bone. In addition, the rivet can be provided with serrations on the head, wherein the rivet attaches soft tissue, such as muscle tendons, to bone.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
136 words
A method of attaching an object to a bone in a patient, said bone having an exterior cortex and an interior cancellous region, comprising the steps of: a) entering said patient to gain access to said bone; b) selecting an area of said cortex to which an object is to be attached; c) forming a hole in said selected area of said cortex; d) placing said object adjacent to said selected area of said cortex; e) providing rivet means with first and second ends, said first end being larger than said second end; f) inserting said rivet means second end through said object and into said hole such that said first end abuts against said object; g) expanding said rivet means second end against said cortex so as to secure said rivet means against said bone.
Claim 2
Independent Claim
136 words
A method of attaching an object to a bone in a patient, said bone having an exterior cortex and an interior cancellous region, comprising the steps of: a) entering said patient to gain access to said bone; b) selecting an area of said cortex to which an object is to be attached; c) forming a hole in said selected area of said cortex; d) placing said object adjacent to said selected area of said cortex; e) providing rivet means with first and second ends, said first end being larger than said second end; f) inserting said rivet means second end through said object and into said hole such that said first end abuts against said object; g) expanding said rivet means second end against said cortex so as to secure said rivet means against said bone.
Claim 3
Independent Claim
181 words
A method of attaching an object to a bone in a patient, comprising the steps of: a) entering said patient to gain access to said bone; b) selecting an area of said cortex to which an object is to be attached, said selected area being a proximal cortex layer, said bone having a distal cortex layer that is separated from said proximal cortex layer by cancellous bone tissue, said proximal cortex layer having an interior side; c) forming a hole in said proximal cortex layer, said hole penetrating into said cancellous tissue; d) placing said object adjacent to said proximal cortex layer; e) selecting blind rivet means suitable for insertion into said hole, said rivet means being provided with first and second ends, said first end being larger than said second end; f) inserting said rivet means second end through said object and into said hole such that said first end abuts against said object; g) expanding said rivet means second end against said interior side of said proximal cortex layer so as to secure said rivet means against said bone.
Claim 4
Independent Claim
181 words
A method of attaching an object to a bone in a patient, comprising the steps of: a) entering said patient to gain access to said bone; b) selecting an area of said cortex to which an object is to be attached, said selected area being a proximal cortex layer, said bone having a distal cortex layer that is separated from said proximal cortex layer by cancellous bone tissue, said proximal cortex layer having an interior side; c) forming a hole in said proximal cortex layer, said hole penetrating into said cancellous tissue; d) placing said object adjacent to said proximal cortex layer; e) selecting blind rivet means suitable for insertion into said hole, said rivet means being provided with first and second ends, said first end being larger than said second end; f) inserting said rivet means second end through said object and into said hole such that said first end abuts against said object; g) expanding said rivet means second end against said interior side of said proximal cortex layer so as to secure said rivet means against said bone.
Claim 5
Dependent Claim
53 words
The method of claim 2 wherein said step of expanding said rivet means second end comprises using pneumatic actuation means, said rivet means being provided with a mandrel for expanding said second end, said mandrel being pulled out of said hole by said pneumatic actuation means to expand said rivet means second end.
Claim 6
Dependent Claim
27 words
The method of claim 2 further comprising the step of removing said rivet means from said bone after said rivet means has been secured to said bone.
Claim 7
Dependent Claim
19 words
The method of claim 4 wherein said step of removing said rivet means comprises drilling through said rivet means.
Claim 8
Dependent Claim
47 words
The method of claim 2, wherein: a) said step of selecting an area of said cortex comprises selecting an ascetablum region of a pelvic bone; and b) said step of placing said object adjacent to said proximal cortex layer comprises placing a hip socket in said ascetablum.
Claim 9
Dependent Claim
55 words
The method of claim 2, wherein: a) said step of selecting an area of said cortex comprises selecting a location in which to secure a plate; b) said step of placing of said object adjacent to said proximal cortex layer comprises placing said plate across a site which is to be fixated by said plate.
Claim 10
Independent Claim
163 words
A method of attaching soft tissue to a bone in a patient, comprising the steps of: a) entering said patient to gain access to said bone; b) selecting an area of said cortex to which said tissue is to be attached; c) forming a hole in said selected area of said cortex; d) placing said tissue adjacent to said selected area of cortex; e) providing rivet means with first and second ends, said first end having a head, said head having an engaging surface that is provided with gripping means for gripping said tissue; f) inserting said rivet means second end through said tissue and into said hole such that said head engaging surface and said gripping means contacts said tissue; g) expanding said rivet means second end against said cortex so as to secure said rivet means against said bone with said tissue being interposed between said bone and said rivet means head, wherein said gripping means serves to secure said tissue.
Claim 11
Independent Claim
163 words
A method of attaching soft tissue to a bone in a patient, comprising the steps of: a) entering said patient to gain access to said bone; b) selecting an area of said cortex to which said tissue is to be attached; c) forming a hole in said selected area of said cortex; d) placing said tissue adjacent to said selected area of cortex; e) providing rivet means with first and second ends, said first end having a head, said head having an engaging surface that is provided with gripping means for gripping said tissue; f) inserting said rivet means second end through said tissue and into said hole such that said head engaging surface and said gripping means contacts said tissue; g) expanding said rivet means second end against said cortex so as to secure said rivet means against said bone with said tissue being interposed between said bone and said rivet means head, wherein said gripping means serves to secure said tissue.
