A bone material dispensing system is provided. The bone material dispensing system comprises a funnel having a proximal portion, the proximal portion comprising a top end and a bottom end, the top end opposite the bottom end, the top end comprising a surface having a protrusion configured to receive a locking member of a bone material dispensing device and the bottom end comprising a connector configured to secure the funnel to the bone material dispensing device. A bone material dispensing system comprises a pusher and a holder is provided. A method of dispensing bone material with the bone material dispensing system is also provided.

Bone material dispensing system and methods of use

Provided is a compression resistant implant configured to fit at or near a bone defect to promote bone growth, the compression resistant implant comprising porous ceramic particles in a biodegradable polymer, and an oxysterol disposed in or on the compression resistant implant. Methods of making and use are further provided.

Compression resistant implants including an oxysterol and methods of use

Provided is a compression resistant implant configured to fit at or near a bone defect to promote bone growth. The compression resistant implant comprises a biodegradable polymer in an amount of about 0.1 wt % to about 20 wt % of the implant and a freeze-dried oxysterol in an amount of about 5 wt % to about 90 wt % of the implant. Methods of making and use are further provided.

Implants having a drug load of an oxysterol and methods of use

A bone material dispensing device is provided. The bone material dispensing device comprises a housing having a proximal end, a distal end, and a longitudinal axis, the proximal end having a first opening and the distal end comprising a frame having a front wall, a back wall, and an air gap, the back wall having a back opening and the front wall having a second opening such that the first opening, the back opening and the second opening are configured to slidably receive at least a portion of a plunger, the front wall comprising a generally flat contact surface configured to engage a funnel; and a locking member pivotably connected to an upper surface of the housing and extending adjacent to the upper surface of the housing, the locking member comprising a locking surface extending adjacent to the distal end of the housing, the locking member being movable in a locking position to lock the portion of the funnel with the housing. A bone material dispensing system and a method of implanting bone material with the bone material dispensing system are also provided.

Bone material dispensing device with distal frame

A bone material dispensing system is provided. The bone material dispensing system comprises a loading device having a perimeter surrounding a base plane and a rim, the perimeter comprising a side wall extending along a longitudinal axis and a bar joining the side wall at a corner of the perimeter and extending in a direction transverse to the longitudinal axis, the base plane comprising a loading surface bordered by the side wall along the longitudinal axis, the loading surface having an end edge extending in a direction transverse to the longitudinal axis such that the side wall, the bar and the end edge form a rim adjacent to the loading surface and the bar. A method of loading bone material with the bone material dispensing system is also provided.

A method of delivering a therapeutic agent to a nucleus pulposus of an intervertebral disc is provided. The method comprises inserting a delivery tool containing the therapeutic agent through an anterior portion, a lateral portion, or an anterolateral portion of an annulus fibrosus and into the nucleus pulposus of the intervertebral disc; and delivering the therapeutic agent to the nucleus pulposus of the intervertebral disc. Devices and kits are also provided.

Methods and devices for delivering therapeutic materials to the intervertebral disc

Provided is an implant configured to fit at or near a bone defect to promote bone growth. The implant comprises an oxysterol uniformly disposed in an acellular tissue matrix (ATM). The acellular tissue matrix can be porcine collagen, which in some cases is crosslinked. The implant can contain an acellular porcine crosslinked collagen in an amount of about 5 wt. % to about 25 wt. % of the implant and an oxysterol in an amount of about 5 wt. % to about 90 wt. % of the implant. The oxysterol can be Oxy133 monohydrate or an Oxy133 polymorph. Methods of making and using the implant are further provided.

Moldable formulations containing an oxysterol in an acellular tissue matrix

An approach is provided for delivering therapeutic materials to an intervertebral disc via a sub-ligamentous space. The approach includes positioning a tool at an interface of a longitudinal ligament and an outer surface of the intervertebral disc, in which the interface is the sub-ligamentous space. The tool may include a first needle and a second needle housed within the first needle. An insertion end of the first needle may include a shallow beveled end. The approach includes inserting the insertion end of the first needle into the sub-ligamentous space. The approach includes deploying the second needle from within the first needle into at least one of an annulus and a nucleus of the intervertebral disc. The approach includes delivering the therapeutic materials to the at least one of the annulus and the nucleus.

Delivery of therapeutic material via sub-ligamentous space

Provided is a lyophilized implant configured to fit at or near a bone defect to promote bone growth, the lyophilized implant containing a biodegradable polymer in an amount of about 0.1 wt. % to about 20 wt. % of the implant, mineral particles in an amount from about 0.1 wt. % to about 75 wt. % of the implant, and an oxysterol in an amount of about 5 wt. % to about 90 wt. % of the implant. Methods of making and using the implant are further provided.

Lyophilized moldable implants containing an oxysterol

Provided is a slow release composition to promote bone growth, the slow release composition comprising: an oxysterol encapsulated in a biodegradable polymer to control the release of the oxysterol. Methods of making and use are further provided.
