Abstract

A surgical cable and crimp device is provided. The cable has an enlargement (bead) affixed to one of its ends. The crimp member includes two holes. One of the holes includes a slot and a cavity. The cavity is sized to accept the bead of the cable, and the slot is sized to receive the flexible cable but not allow the bead to pass through. The other hole is a simple through hole. The cable can be inserted to loop the bone isolated from the crimp member. After the beaded end of the surgical cable is fastened to the crimp, the cable is passed through the simple through hole. The cable is then tensioned by the application thereto of a tensioning tool with the tool applied to the cable and to an abutment face of the crimp member.

Claims

1. A fastening apparatus for fixing bone elements comprising:

a. a flexible cable having a first end, a second end, and a width, the first end including an enlargement greater than the width of the cable;

b. a crimp member including

i. a first hole having a length, a slot, a proximal opening formed on a first planar face of the crimp member and opening into a proximal portion of the slot, a distal opening formed on a second planar face of the crimp member and opening into a distal portion of the slot, and a planar opening formed on a third planar face of the crimp member and opening into the proximal and distal portions, wherein the third planar face is perpendicular to the first and second planar faces, the proximal opening being configured and dimensioned to accept the enlargement at the first end of the cable, the proximal portion of the slot being configured and dimensioned to permit the enlargement of the cable to pass therethrough, the planar opening being configured and dimensioned to permit the width of the cable to pass therethrough and prevent the enlargement from passing therethrough, and the distal portion of the slot configured and dimensioned to permit the width of the cable to pass therethrough and prevent the enlargement from passing therethrough, and

ii. a second hole having a length, the second hole configured and dimensioned to permit insertion of the second end of the cable through the second hole.

2. The apparatus of claim 1, wherein the crimp member is configured for attachment to the flexible cable after the cable has been looped around a bone.

3. The apparatus of claim 2, wherein the crimp member is attached to the cable by insertion of the first end of the cable into the first hole of the crimp member and insertion of the second end of the cable through the second hole of the crimp member to form a loop of adjustable diameter.

4. The apparatus of claim 1, wherein the first and second holes of the crimp member are parallel straight holes.

5. The apparatus of claim 1, wherein the first and second holes of the crimp member are coplanar.

6. The apparatus of claim 1, wherein the proximal portion of the first hole is coplanar with the second hole.

7. The apparatus of claim 1, wherein the distal portion of the first hole is substantially parallel to the second hole.

8. A fastening apparatus for fixing bone elements comprising:

a. a flexible cable having a width, an enlarged first end, and a second end; and

b. a crimp member including

i. a first hole having a length, a proximal opening formed on a first planar face of the crimp member and opening into a proximal portion of the first hole, a distal opening formed on a second planar face of the crimp member and opening into a distal portion, and a planar opening formed on a third planar face of the crimp member and opening into the proximal and distal portions, wherein the third planar face is perpendicular to the first and second planar faces, the proximal portion of the first hole configured and dimensioned to accept the enlarged first end of the cable, the planar opening configured and dimensioned to permit the width of the cable to pass therethrough while preventing the enlarged first end to pass therethrough, and the distal portion of the first hole configured and dimensioned to prevent the enlarged first end from passing therethrough while permitting the width of the cable to pass therethrough, and

ii. a second hole having a length, the second hole configured and dimensioned to permit insertion of the second end of the cable through the second hole;

wherein the crimp member is configured for attachment to the flexible cable after the flexible cable has been wrapped around a bone.

9. The apparatus of claim 8, wherein the proximal portion of the first hole defines a first axis and the distal portion of the second hole defines a second axis, and the first and second axes are not collinear.
