  • Publication number: 20030078617
    Abstract: Unitary surgical devices are disclosed. One group of the illustrated devices has a pair of biocompatible, bioresorbable anchors connected to fixed lengths suture. The anchors and fixed length of suture are connected to each other prior to surgery. Another group of unitary surgical devices has a pair of fixating mechanisms connected to a base prior to surgery. The second group of illustrated devices generally includes extracellular matrix material either as part of the base or supported on the base. The extracellular matrix material serves as tissue regenerating material. In the second group of unitary surgical devices, the fixating mechanisms illustrated generally comprise suture, anchors or pre-formed holes in the base. All of the illustrated unitary surgical devices are useful in repairing a damaged meniscus. The first group of unitary surgical devices can be used to approximate inner surfaces of a tear in the meniscus.

  • Publication number: 20030049299
    Abstract: A method of making an implantable scaffold for repairing damaged or diseased tissue includes the step of suspending pieces of an extracellular matrix material in a liquid. The extracellular matrix material and the liquid are formed into a mass. The liquid is subsequently driven off so as to form interstices in the mass. The scaffold may further comprise biological agents that promote tissue repair and healing. Porous implantable scaffolds fabricated by such a method are also disclosed.

  • Publication number: 20030036797
    Abstract: Methods and devices are provided for regenerating a meniscus. The devices comprise a layer of toughened naturally occurring extracellular matrix. The devices may, optionally, further comprise a biologic material to provide a framework for meniscus regeneration. The methods comprise the steps of removing a portion of a meniscus to provide a space, and inserting a device comprising a layer of toughened naturally occurring extracellular matrix into the space.

  • Publication number: 20030036801
    Abstract: An orthopaedic device for repairing and regenerating cartilage includes a plug configured to be positioned in a hole formed in the cartilage and an anchor configured to support the plug. One or both of the plug and the anchor may be formed from naturally occurring extracellular matrix such as small intestine submucosa. A method for repairing and regenerating cartilage is also disclosed.

  • Publication number: 20030032961
    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.

  • Publication number: 20030021827
    Abstract: Methods of making a hybrid biologic/synthetic scaffold for repairing damaged or diseased tissue are provided. The methods include the step of suspending pieces of an extracellular matrix material in a liquid to form a slurry, and coating a synthetic mat with the slurry, or mixing or layering the slurry with a synthetic polymer solution. The liquid is subsequently driven off so as to form a foam. Porous implantable scaffolds fabricated by such a method are also disclosed.
