Abstract
A tendon repair implant and related surgical instruments are disclosed. The tendon repair implant has an elongated substrate with a convex side and a concave side with a plurality of spikes protruding from the concave side at an angle that optimally retains a. tendon to the bone that the tendon repair implant is subsequently attached to. A surgical retainer for the tendon repair implant is also provided that releasably retains the tendon repair implant during surgery and implantation, A drill guide instrument for the tendon repair implant Is also provided that allows the surgeon to precisely place fastening holes in the bone prior to implantation of the tendon repair implant.
Claims23
A tendon repair implant comprising:
- an elongated substrate comprising a convex side and a concave side;
- a plurality of spikes protruding from the concave side;
- wherein each spike protrudes from the concave side of the substrate at an angle in the range of zero degrees to 45 degrees with respect to a line perpendicular to the concave surface of the substrate where the spike originates;
- a first attachment for fastening the substrate to a mammalian bone with the concave side of the substrate facing the mammalian bone;
- a second attachment for fastening the substrate to a mammalian bone with the concave side of the substrate facing the mammalian bone,
- wherein the first attachment comprises a first expandable flange structure joined with a first hole in the elongate substrate, and the second attachment comprises a second expandable flange structure joined with a second hole in the elongate substrate, the first and second expandable flange structures each comprising a base end at the concave side, only a singular flange defining a terminal flanged end, a tapered sleeve body extending fully between the base end at the concave side and the terminal flanged end that narrows as it extends from the base end to the terminal flanged end in an unexpanded state of the respective first or second expandable flange structure, and one or more slots extending from the base end through the tapered sleeve body and the terminal flanged end, the base end of the first expandable flange structure mechanically coupled to, or integral with, a first portion of the elongated substrate, and the base end of the second expandable flange structure mechanically coupled to, or integral with, a second portion of the elongated substrate;
- and
- wherein each spike of the plurality of spikes is positioned between the first attachment and the second attachment.

A tendon repair implant comprising:
- an elongated substrate comprising a convex side and a concave side, wherein the convex side of the elongate substrate comprises a directional indicator that provides a visual indication of proper orientation of the tendon repair implant relative to a surgical area;
- a plurality of spikes protruding from the concave side;
- wherein each spike protrudes from the concave side of the substrate at an angle in the range of zero degrees to 45 degrees with respect to a line perpendicular to the concave surface of the substrate where the spike originates;
- a first bone attachment device for fastening the substrate to a mammalian bone with the concave side of the substrate facing the mammalian bone;
- and
- a second bone attachment device for fastening the substrate to a mammalian bone with the concave side of the substrate facing the mammalian bone;
- wherein the first bone attachment device and the second bone attachment device each comprise an expandable flange structure joined with a hole in the substrate where the hole allows for placement and entry of a surgical screw into the expandable flange structure of the respective bone attachment device;
- and
- wherein the expandable flange structure of each bone attachment device comprises only a singular flange defining a terminal flanged end, and a tapered sleeve body extending fully between the concave side of the elongated substrate and the terminal flanged end that narrows as it extends from the concave side to the terminal flanged end in an unexpanded state of the expandable flange structure, and wherein each expandable flange structure is segmented to define one or more channels extending from the concave side of the elongated substrate and through the tapered sleeve body and the terminal flanged end to allow for expansion of the expandable flange structure when a surgical screw is entered into the expandable flange structure.
