Claim 6
Dependent Claim
26 words
The device as claimed in claim 1, further comprising a head member configured for attachment to said filament member to facilitate securement of tissue relative thereto.
Claim 7
Dependent Claim
31 words
The device as claimed in claim 1, further comprising a second anchor member configured for attachment relative to said filament member to facilitate securement of a second bone member relative thereto.
Claim 8
Independent Claim
134 words
A device for attaching a first bone to a second bone, said first bone defining a pre-drilled bone hole therein, said device comprising: an elongate, flexible filament member, a first anchor member defining an external surface configured to engage said pre-drilled hole and secure said anchor member relative to said first bone, said anchor member also defining an internal bore to be substantially aligned with said pre-drilled hole and configured to accept a first end of said filament member, said anchor member also defining an engagement means configured to engage said flexible filament member within said first anchor have to discourage removal of said filament from said first anchor member when in place in said bone; and a second anchor member for attaching said second end of said filament member to said second bone.
Claim 9
Independent Claim
134 words
A device for attaching a first bone to a second bone, said first bone defining a pre-drilled bone hole therein, said device comprising: an elongate, flexible filament member, a first anchor member defining an external surface configured to engage said pre-drilled hole and secure said anchor member relative to said first bone, said anchor member also defining an internal bore to be substantially aligned with said pre-drilled hole and configured to accept a first end of said filament member, said anchor member also defining an engagement means configured to engage said flexible filament member within said first anchor have to discourage removal of said filament from said first anchor member when in place in said bone; and a second anchor member for attaching said second end of said filament member to said second bone.
Claim 10
Dependent Claim
114 words
The device as claimed in claim 7, wherein said second bone also defines a pre-drilled second hole therein, and wherein said second anchor member defines an external surface configured to engage said pre-drilled second hole and secure said anchor member relative to said second bone, said second anchor member also defining an internal second bore substantially aligned with said pre-drilled hole and configured to accept a second length of said filament member, said second anchor member also defining an engagement means configured to engage said second length of said flexible filament member within said second anchor have to discourage removal of said filament from said second anchor member when in place in said bone.
