Anchor for bone and soft tissue
View Patent ↗The invention is directed to an anchor for fixing a tendon or a ligament in a bone comprising: an elongated tubular body having a bore extending along a longitudinal axis, said tubular body comprising first and second independent parts slidably contacting each other, the first and second independent parts each having an outer circumferential surface along a length thereof parallel to the longitudinal axis, and each having an elongated partial inner bore, such that the tubular body is capable of mounting a tendon or ligament within the partial inner bore.
1. An anchor for fixing a tendon or a ligament in a bone comprising: an elongated tubular body having a central bore extending along a longitudinal axis of the tubular body, said tubular body defined by a repeating overlap between a first wire-form pattern and a second wire-form pattern, the first and second wire-form patterns each having an elongated partial inner bore parallel to the central bore, such that the tubular body is capable of mounting a tendon or ligament within the partial inner bore of said first and second wire-form patterns.
2. The anchor of claim 1 further comprising a pin inserted into the central bore.
3. The anchor of claim 2 wherein insertion of the pin into the central bore causes an expansion of the central bore.
4. A method for anchoring a tendon or ligament in a bone comprising the steps of:
providing an elongated tubular body having a central bore extending along a longitudinal axis, said tubular body defined by a repeating overlap between a first wire-form pattern and a second wire-form pattern the first and second wire-form patterns each having an elongated partial inner bore parallel to the central bore;
inserting one or more tendons or ligaments into the elongated partial inner bore of said first and second wire-form patterns;
inserting a pin into the central bore of the tubular body and expanding the diameter of the central bore; and
anchoring the tendon or ligament in a bone.
5. The anchor of claim 1 , wherein the first wire-form pattern comprises a repeating first shape and the second wire-form pattern comprises a repeating second shape.
6. The anchor of claim 2 , wherein the elongated partial inner bores of the first and second wire-form patterns decrease in surface area in response to the insertion of the pin.
7. The anchor of claim 2 , wherein a circumference of the tubular body increases in response to the insertion of the pin.
8. The method of claim 4 , wherein inserting the pin decreases a surface area of the elongated partial inner bores of the first and second wire-form patterns.
