A device for collecting a bone graft material comprises a canister extending defining a filter-receiving space therein, the canister including a connection for connecting to a vacuum source, a proximal end of the canister including a first locking feature and a filter element sized and shaped to be received within the filter-receiving space of the canister, the filter element including a channel extending therethrough, the channel defined via a mesh material and a proximal end of the filter element including a second locking feature releasably engageable with the first locking feature of the canister via a rotation of the filter element about a longitudinal axis thereof relative to the canister in combination with an extractor sized and shaped to be received within the channel of the filter element, the extractor defining a graft material receiving space therein and being releasably engageable with the extractor.

The present invention is directed to a fiber, preferably bone fiber, having a textured surface, which acts as an effective binding substrate for bone-forming cells and for the induction or promotion of new bone growth by bone-forming cells, which bind to the fiber. Methods of using the bone fibers to induce or promote new bone growth and bone material compositions comprising the bone fibers are also described. The invention further relates to a substrate cutter device and cutter, which are effective in producing substrate fibers, such as bone fibers. The present invention is also directed to a device for the growth of new bone or bone-like tissue under in vitro cell culture conditions.

A bone implant holding and shaping tray is provided. The tray includes a first segment having a distal end and a first surface sized to hold and shape at least a portion of the bone implant with bone material. The tray includes a second segment having a second surface sized to hold and shape at least a portion of the bone implant with bone material, the second segment having a proximal end configured to be coupled to the distal end of the first segment so as to extend the first surface to hold and shape the bone implant. Methods of making and using the bone implant holding and shaping tray are also provided.

Apparatus for producing strips of bone fibre comprising a vice for securing a section of rigid bone with which said apparatus is used, said vice defining a containment area and having a compression axis with which a longitudinal axis of said bone is substantially aligned in use, an arm for reciprocal linear movement along a movement axis between a rearward position and a forward position, said movement axis being parallel with said compression axis and spaced therefrom in a lateral plane, a first drive mechanism for moving said arm along said movement axis in a reciprocal manner, and a cutting head comprising a first row of cutting teeth, which cutting head is mounted to a first end of said arm with said first row of cutting teeth coincident with said containment area and disecting said lateral plane, and a method of producing a DBM fibres product using such apparatus.

A device (10) for collecting and processing bone fragments is disclosed. The device comprises a chamber member (12), a press member (14), an intake port (16), and a vacuum port (18). A compression surface (20) and a filter support surface (22) configured to support a filter are defined by said chamber and/or press member. The intake port is on the chamber and/or press member and is configured to receive a composition comprising bone fragments. The vacuum port is on the chamber and/or press member. The chamber member and the press member are rotationally coupled with one another. The composition is acquired through the intake port and collected between the compression surface and the filter support surface. The application of rotational force to the chamber and/or press member in a first direction moves the compression surface and the filter support surface together to compress the composition therebetween to compact, and further remove filtrate from the composition.

A bone milling device for grinding bone during a bone grafting procedure including a pair of opposing dead stops, one or more provided on a rotating plate of a rotatable mill and one or more provided on a stationary plate to prevent adhesion of respective arrays of grinding teeth.

A bone cutting assembly includes a manually actuated upper cutting element that carries a plurality of cutting blades configured to cut through frozen bone segments. A lower cutting element supports a bone segment to be cut and can include cutting blades aligned with the cutting blades of the upper cutting assembly. A pivoting linkage or a rack and pinion arrangement can be provided between the upper cutting element and a manually operated handle to provide sufficient mechanical advantage or leverage to allow an operator to manually cut through the bone.

A system for harvesting bone material from a bone may include a rotary cutter defining a rotary cutter longitudinal axis extending between a rotary cutter proximal end and a rotary cutter distal end. The rotary cutter may have a drive shaft configured to receive input torque, and an osteochondral cutter configured to cut the tissue and receive the tissue material in response to rotation of the osteochondral cutter under pressure against the tissue. The system may further include a bone port defining a bone port longitudinal axis extending between a bone port proximal end and a bone port distal end. The bone port may have a bone port cannulation sized to closely fit over the osteochondral cutter. At least one of the bone port proximal end and the bone port distal end may be securable to the tissue. A stratiform tissue graft may be delivered through the bone port.

A mill head for replaceable attachment to a base so as to collectively form a bone mill. The mill head includes shell with: a first opening in which bone stock is introduced into the head; and a second opening through which the bone chips are discharged. A cutting device is mounted in the shell to both rotate and move laterally. Attached to the cutting device are coupling features for engaging a drive spindle able to rotate the cutting device. Also attached to the housing is an alignment feature. The alignment feature engages a complementary alignment feature associated with the drive spindle so as a result of the engagement of the alignment features, the cutting device moves within the shell so that the cutting device coupling features are positioned to engage the drive spindle.
