    摘要: A method for augmenting a void or treating a wound in a body cavity involves applying a three-dimensional, resorbable collagen scaffold derived from a vascularized portion of a perfusion-decellularized mammalian tissue or organ to the site of the void or body cavity. This application allows for cellular infiltration, integration, or remodeling of the surrounding body tissue into one or more vascular pathways of the scaffold. The scaffold is applied in a manner that ensures at least three surfaces of the scaffold make contact with the surrounding body tissue. The scaffold includes a plurality of pores, resulting in a surface area significantly larger than a poreless scaffold of the same outer dimensions. The method can also include placing milled fibers to any undermining or irregularities in the void or cavity before applying the scaffold.

    摘要: A subperiosteal syringe assembly for storing, containing and delivering bone graft material to a location within the tissue of a jaw for use in a medical procedure. The syringe assembly has a lumen body that is maneuverable within the subperiosteal tissue to deposit bone graft material at the desired surgical site. Embodiments include a lumen body that has a flat shape, such as an elliptical shape. A plunger is provided to deliver the syringe contents. The syringe may be loaded with bone graft material, and some embodiments may be supplied pre-loaded with bone graft material. An end cap seals the open end of the lumen, and may function as a septum that may be punctured with a needle to introduce a liquid substance, such as a growth factor, into the lumen where the bone material is stored. The syringe may be designed to incorporate surgical navigation and laparoscopic systems.
