Devices from naturally occurring biologically derived materials
First Claim
1. An orthopedic device for attaching soft tissue such as cartilage, ligament and tendons to bone, the device having a head portion configured to engage soft tissue and a body portion configured to engage and attach to the bone, the head portion and body portion being monolithic and formed from naturally occurring extracellular matrix (ECM) cured to be rigid and hardened to facilitate attachment to the bone.

Abstract
Orthopaedic devices are disclosed. The devices include a part that is made of extracellular matrix material that has been hardened. One method of hardening the extracellular matrix is to comminute naturally occurring extracellular matrix and dry the comminuted material. The hardened extracellular matrix material can be machined to form a variety of orthopaedic devices.

- 1. An orthopedic device for attaching soft tissue such as cartilage, ligament and tendons to bone, the device having a head portion configured to engage soft tissue and a body portion configured to engage and attach to the bone, the head portion and body portion being monolithic and formed from naturally occurring extracellular matrix (ECM) cured to be rigid and hardened to facilitate attachment to the bone.
- 25. A device for repairing a tear in a cartilaginous surface such as a meniscus, the device comprising strips of naturally occurring extracellular matrix laminated together to form a body portion to be placed down into the tear to extend along the tear, and one or more tacks coupled to the body portion to secure it in the tear, each of the one or more tacks being formed from naturally occurring extracellular matrix cured to be hard and rigid.
- 39. An orthopedic device for attaching or repairing tissue, the device comprising two spaced apart barbs, each barb having a sharpened distal end and a proximal end, and a member connecting the proximal ends of the barbs, the barbs being formed from naturally occurring extracellular matrix.
- 51. A device for anchoring a bone plug in an opening formed in a bone, the device comprising a mass of naturally occurring extracellular matrix formed into a rigid and hardened member configured to be wedged in the opening between the bone plug and the bone.
-
60. A method for anchoring a bone plug into an opening formed in a bone for receiving the plug, the method comprising the steps of:
-
(a) providing a member formed into a rigid and hardened mass of naturally occurring extracellular matrix, and (b) placing the member into the opening between the bone plug and the bone. - View Dependent Claims (61, 62, 63, 64, 65, 66, 67, 68, 69, 70)
-
- 71. A device for attaching a soft tissue to a bone that has been prepared with an opening to receive the device, the device being formed from a hardened mass of naturally occurring extracellular matrix to form an elongated body to be received in the opening, the body having a channel therein for receiving a portion of the soft tissue, the body being configured to collapse inwardly to grip and hold the soft tissue portion in the channel when the body is inserted into the opening.
- 79. An orthopedic device comprising a mass of naturally occurring extracellular matrix having a hardness greater than 30 HRD on the Rockwell D Scale.
- 89. A composite orthopedic device comprising two connected portions, each portion comprising naturally occurring extracellular matrix material, each portion having a hardness and a density, wherein one portion is configured for anchoring the device to native tissue and has a hardness of not less than 30 HRD on the Rockwell D Scale and a density greater than 0.5 g/cc, and the other portion has a different configuration, a different hardness and a different density.
- 93. An orthopedic device comprising bioremodelable collageneous tissue matrix having a hardness greater than 30 HRD on the Rockwell D Scale.
- 103. A composite orthopedic device comprising two connected portions, each portion comprising naturally occurring bioremodelable collageneous tissue matrix, each portion having a hardness and a density, wherein one portion has a hardness of no less than 30 HRD on the Rockwell D Scale and a density greater than 0.5 g/cc, and the other portion has a different hardness and a different density.
