    摘要： Bone marrow aspiration devices and methods are disclosed for use in preparing a substrate. In general, the device includes an elongate penetrating element, a chamber adapted to retain a substrate, and a fluid extraction mechanism that is effective to pull fluid through the elongate penetrating element, into the chamber, and through the substrate. The device is particularly advantageous in that it will allow for the removal of fluids from a patient's body and the preparation of a substrate in a single process, thereby providing a more efficient method and device for preparing a substrate.

    摘要： Devices and methods are disclosed for expanding a spinal canal. An implantable device having a shaft with a first cross-sectional dimension distinct from a second cross-sectional dimension can be inserted into an opening in a lamina and rotated 90 degrees to hinge the lamina away from the spinal canal. The implant can have one or more radiused edges, a bulleted tip, one or more lateral extensions for fastening the implantable device to bone, one or more hinged lateral extensions, one or more arcuate protrusions for biting into adjacent bone, an enlarged proximal head to prevent over-insertion, and/or a sleeve disposed therearound to reduce friction. Various embodiments of an insertion apparatus that can be selectively coupled to the implantable device are also disclosed, along with methods of expanding a spinal canal in minimally-invasive procedures using an implantable device and/or an insertion apparatus.

    摘要： A fluid flow system for preparing an implantable substrate is provided having a fluid permeable container that is capable of retaining a biocompatible, implantable substrate, and a driver mechanism for subjecting fluid to a constant force to induce a selected, controlled flow rate of the fluid through a substrate disposed in the container. The system can include a fluid reservoir having an inlet and an outlet, and being effective to selectively retain a fluid. The reservoir is preferably disposed upstream of the container. The system can also optionally include a fluid recycling conduit that is effective to recirculate fluid from the container to the reservoir.
