Abstract
The present invention features systems for orthopedic repair of, for example, a joint. The present systems deviate from conventional systems by virtue of combining a finer prosthetic ligament with a robust anchor. The relationship between these components and their various features are described herein and result in joint reconstruction in human and veterinary settings that is less likely to fail over time.
Claims22
A prosthetic system for surgical repair of a joint, the system comprising a first anchor, a second anchor, a prosthetic ligament, a first separable restraint, and a second separable restraint, wherein:
- the first anchor comprises an elongated body defining a longitudinal tunnel that connects a leading end of the first anchor with a trailing end of the first anchor;
- the second anchor comprises an elongated body defining a longitudinal tunnel that connects a leading end of the second anchor with a trailing end of the second anchor, wherein the first anchor and the second anchor are insertable into bones;
- the first separable restraint is received in a first receiving surface of the trailing end of the first anchor, the first separable restraint defining a first restraint tunnel;
- the second separable restraint is received in a second receiving surface of the second anchor, the second separable restraint defining a second restraint tunnel;
- and
- the prosthetic ligament comprises a plurality of fibers of non-natural polymer that form contiguous loops and the prosthetic system is configured such that, when the system is deployed, a first end of the plurality of fibers is held by the first restraint at the trailing end of the first anchor and a second end of the plurality of fibers is held by the second restraint at the trailing end of the second anchor, such that a first portion of the prosthesis lies within the longitudinal tunnel that connects the leading end of the first anchor with the trailing end of the first anchor and a second portion of the prosthesis lies within the longitudinal tunnel that connects the leading end of the second anchor with the trailing end of the second anchor, wherein the longitudinal tunnel of the first anchor is contiguous with the first restraint tunnel and the longitudinal tunnel of the second anchor is contiguous with the second restraint tunnel;
- wherein at least one of a first pathway formed by the longitudinal tunnel of the first anchor and the first restraint tunnel or a second pathway formed by the longitudinal tunnel of the second anchor and the second restraint tunnel, defines a curvilinear pathway with a radius of curvature that is at least one half of an exit radius of a respective at least one of curved exits of the longitudinal tunnel of the first anchor or the longitudinal tunnel of the second anchor, the curvilinear pathway being a curved line defining a ligament path curved inside the first pathway or the second pathway through which the prosthetic ligament passes, wherein the leading end of the first anchor or the second anchor comprises a curved exit and wherein the curved exit is integral to the leading end of the first anchor or the second anchor or is formed by means of including an eyelet surrounding the longitudinal tunnel at the leading end of the first anchor or the second anchor.
