A composite interbody bone implant device is provided including a body having a non-bone composition, such as a polymer, formed into a shape and including one or more cavities. An osteoinductive material, such as bone allograft tissue, may be retained in the one or more cavities of the body. The body is formable via injection molding and/or machining into a shape and size adapted for implantation at a surgical site. The dimensions of the body include a length, a width and a thickness, and the thickness of the body may be less than at least one of the length and width.

Interbody bone implant device

Effective treatments of pain for extended periods of time are provided. Through the administration of an effective amount of clonidine in a drug depot at or near a target site, one can relieve pain caused by diverse sources, including but not limited to spinal disc herniation (i.e. sciatica), spondilothesis, stenosis, discogenic back pain and joint pain. When appropriate drug depot formulations are provided within biodegradable polymers, this pain relief can be continued for at least fourteen days.

Clonidine compounds in a biodegradable polymer

Bone implant compositions are provided that include a body made of cortical bone extending along an axis between a first end and a second end. The body includes an outer surface configured to engage host bone of a patient and at least one recess extending transverse to the axis into the outer surface of the body configured for disposal of an insert. At least one insert made of demineralized bone is disposed in the at least one recess.

Osteograft implant

A bone void filler material is provided for sustained release of a therapeutic agent. The bone void filler material comprising a biodegradable matrix having ceramic cement beads comprising calcium sulfate, and ceramic particles disposed within the matrix. The ceramic cement beads are loaded with the therapeutic agent to cause sustained release of the therapeutic agent. Methods of use are also disclosed.

Bone void filler having calcium coatings

A device for separating particulate matter (e.g., cells) from a liquid including a housing defining an elongate chamber disposed between a receiving end and a dispenser end, a plunger slidably inserted within the chamber from the receiving end, an upper disc and a lower disc each independently slidably affixed to the plunger, the lower disc facing the dispenser end and including at least one filter arrangement, and a liquid including particulate matter disposed within the chamber when the upper disc and lower disc are in an aspiration mode. The upper disc is independently slidable with respect to the lower disc to achieve a filtration mode.

Filtration device

A delivery system comprising a covering having at least two compartments is provided. A first compartment contains a first therapeutic agent and the second compartment can be unfilled and is configured to receive a second therapeutic agent. The first compartment and the second compartment are separated by at least one removable separation member, for example a drawstring, that can be pulled to allow the first and second therapeutic agents to mix prior to delivery at a selected surgical site. Either the first or second compartment of the covering define an opening further comprising a pre-attached sealing member, which can be a flap sealable by heat, sutures, pressing or interference fittings. The opening of the empty compartment can be configured to receive a filling member, such as a funnel fitted with a spring loaded clip for temporary attachment to the covering. A method of treating a bone defect in a patient utilizing the delivery system is also provided.

Delivery systems

An expandable implant device for implantation at a surgical site is provided. The implant device is made of cortical bone and includes a top and bottom piece, both pieces configured to couple with each other. The top piece has superior and inferior surfaces, and at least a tapered leading end configured to distract open an intervertebral disc space so that the top piece can be slidably inserted over the bottom piece until a desired overlap is achieved. A composite interbody bone implant device is also provided including a body skeleton having a non-bone composition, such as a polymer, formed into a shape and including one or more cavities which can be filled with other material, for example, allograft material. A method of placing an expandable device into a disc space is also provided.

Methods of making and osteoinductive compositions are provided. The method includes mixing isolated periosteum tissue with a demineralized bone matrix to form the osteoinductive composition. The periosteum tissue is isolated from the surface of large bones such as femur, tibia, humerus or a mixture thereof. The demineralized bone matrix can include a plurality of surface demineralized or fully demineralized bone fibers, bone chips, bone particles or mixtures thereof. In the osteoinductive composition the substantially isolated periosteum tissue is from about 0.5% wt. to about 10% wt. A method for repairing a bone defect is also provided. The method of treatment includes applying to the bone defect a substantially effective amount of a mixture of isolated periosteum tissue and demineralized bone matrix.

Demineralized bone matrix with improved osteoinductivity

A spinal implant is provided. The spinal implant includes a body extending between a proximal end and a distal end. The proximal end defines a notch configured for disposal of a first vertebra. The distal end includes a protrusion configured for disposal in a second vertebra. The proximal and distal ends are movable relative to one another between an unexpanded position in which the spinal implant is inserted between lamina and an expanded position in which the spinal implant is disposed between the lamina.

Intervertebral spinal implant and method

Implantable medical devices and methods are provided that have one or more statins disposed therein. The medical devices may be implanted at near or in a bone defect to enhance bone growth. In some embodiments, the medical device provided allows for sustain release of the statin and facilitates bone formation and repair of the fracture site.

Methods and compositions to enhance bone growth comprising a statin

The invention provides methods and composition developed to be used with imaging techniques and useful for diagnosis and monitoring the pain generator(s) of axial pain with or without radiculopathy and methods for screening therapeutic compounds potentially useful for treating axial pain with or without radiculopathy. Alternatively, degenerated discs can be monitored and treated before occurrence of a pathological pain condition. Pain markers and markers of degeneration include markers of neuronal, vascular, immune and matrix elements.

Compostions and methods for diagnosis of axial pain with or without radiculopathy

A bone void filler material is provided that is configured for sustained release of a therapeutic agent. The bone void filler material comprises a biodegradable matrix having ceramic particles and cement beads disposed within the matrix, the cement beads loaded with the therapeutic agent to cause sustained release of the therapeutic agent. Methods of use are also disclosed.

Bone void filler having sustained therapeutic agent release

Bone implant compositions and methods are provide that have an outer surface, the outer surface comprising demineralized bone and having a cavity disposed in the outer surface, the cavity having a demineralized bone material coated therein; and an inner surface of the bone implant comprising cortical bone, the inner surface contacting the outer surface. The bone implant compositions and methods provided are osteoinductive and allow rapid bone fusion.

Bone implants and methods comprising demineralized bone material

Effective treatments of pain for extended periods of time are provided. Through the administration of an effective amount of clonidine and a gamma-aminobutyric acid compound at or near a target site, one can relieve pain caused by diverse sources, including but not limited to spinal disc herniation (i.e. sciatica), spondilothesis, stenosis, discogenic back pain and joint pain, as well as pain that is incidental to surgery. When appropriate formulations are provided within biodegradable polymers, this relief can be continued for at least three days. In some embodiments, the relief can be for at least twenty-five days, at least fifty days, at least one hundred days, at least one hundred and thirty-five days or at least one hundred and eighty days.
