Abstract
Abstract A medical anchor device for implantation into a bone of a patient includes a staple having a leading, bone-boring tip for self-tapping a hole, a trailing, driven end for receiving implanting force to self-tap and implant said staple into the bone of a patient, and an attached suture thread. The staple has a longitudinal axis which passes through the tip and the driven end, the longitudinal axis changing shape upon implantation of the staple into a bone. A method of treating a patient includes ejecting and implanting the staple comprising a suture thread secured thereto into a bone by self-tapping a hole in the bone and securing the suture thread to a portion of the body's anatomy.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
87 words
An anchor device for plantation into a bone of a patient, comprising: a staple having a leading, bone-boring tip for self-tapping a hole; a trailing, driven end for receiving implanting force to self-tap and implant said staple into the bone of a patient; and, an attached suture thread; said staple, being formed from an elastic material, said staple being initially of a curved shape aid being deformed to a straight shape, said staple reverting back to said curved shape upon implantation of said staple into the bone.
Claim 2
Dependent Claim
87 words
An anchor device for plantation into a bone of a patient, comprising: a staple having a leading, bone-boring tip for self-tapping a hole; a trailing, driven end for receiving implanting force to self-tap and implant said staple into the bone of a patient; and, an attached suture thread; said staple, being formed from an elastic material, said staple being initially of a curved shape aid being deformed to a straight shape, said staple reverting back to said curved shape upon implantation of said staple into the bone.
Claim 3
Dependent Claim
20 words
An anchor device as claimed in claim 1, wherein said suture thread is attached through a hole in said staple.
Claim 4
Dependent Claim
20 words
An anchor device as claimed in claim 2, wherein said hole is located between said tip and said driven end.
Claim 5
Dependent Claim
29 words
An anchor device as claimed in claim 1, wherein said staple further comprises barbs which project outwardly from said driven end when said staple is ejected into the bone.
Claim 6
Dependent Claim
30 words
An anchor device as claimed in claim 1, further comprising a crimped bore in said staple which frictionally holds said suture thread during implantation of said staple into the bone.
Claim 7
Dependent Claim
20 words
An anchor device as claimed in claim 5, wherein said crimped bore extends at an angle to said longitudinal axis.
Claim 8
Dependent Claim
24 words
An anchor device as claimed in claim 1, wherein said driven end of said staple is substantially flat prior to implantation into the bone.
Claim 9
Dependent Claim
31 words
An anchor device as claimed in claim 1, wherein said anchor device is formed from wire bent into a U-shape with said suture thread held in the bight of the staple.
Claim 10
Dependent Claim
32 words
An anchor device as claimed in claim 1, wherein said staple is initially substantially flat and upon implantation into a patient's bone changes to a shape having a split tail-like driven end.
Claim 11
Dependent Claim
31 words
A method as claimed in claim 21, wherein said anchor reverts from said straight shape back to said curved shape as a result of the removal of stress from said staple.
Claim 12
Independent Claim
79 words
A method of treating a patient comprising: providing a staple having a suture thread attached thereto, said staple being initially of a curved shape and comprising an elastic material maintained in a straight shape; ejecting and implanting said staple into a bone by self-tapping a hole in said bone; allowing said staple to revert back to its curved shape to provide fixation of said staple in the bone; and, securing said suture thread to a portion of the body.
Claim 13
Independent Claim
79 words
A method of treating a patient comprising: providing a staple having a suture thread attached thereto, said staple being initially of a curved shape and comprising an elastic material maintained in a straight shape; ejecting and implanting said staple into a bone by self-tapping a hole in said bone; allowing said staple to revert back to its curved shape to provide fixation of said staple in the bone; and, securing said suture thread to a portion of the body.
Claim 14
Dependent Claim
37 words
A method as claimed in claim 11, wherein said step of providing a staple includes providing a staple having a leading tip, a trailing, driven end, and a longitudinal axis extending between said tip and said end.
Claim 15
Dependent Claim
54 words
A method as claimed in claim 12, further comprising the step of changing the orientation of said longitudinal axis of said staple with respect to the bone upon implantation in the bone by moving said longitudinal axis to rest substantially parallel to the surface of the bone to anchor said staple in the bone.
Claim 16
Dependent Claim
26 words
A method as claimed in claim 11, wherein said step of ejecting and implanting a staple includes ejecting and implanting a staple into a shoulder bone.
Claim 17
Dependent Claim
29 words
A method as claimed in claim 11, wherein said step of allowing said staple to revert back to its curved shape comprises the removal of stress from said staple.
