    摘要: An acetabular prosthesis has a shell component that is implantable within bone and a liner component that is matable to the shell by a locking member disposed with the shell component. The shell has a generally convex bone engaging outer surface and a generally concave inner surface. A groove is formed in the inner surface of the shell and extends about at least a portion of the inner circumference of the shell. The liner has an inner concave surface and an outer, convex surface with a shape complementary to and matable within the inner surface of the shell. One or more deformable tabs are formed on the locking member, adapted for securing the liner within the shell. The liner may be joined to the shell by press fitting the two components together such that the locking members engages one or more positive surface ridges on the liner.

    摘要: A laminated, bioimplantable dural graft product is configured for use as both an onlay graft and a suturable graft. The dural graft product is sufficiently pliable so as to sufficiently conform to a curvature of a tissue surface to which it is applied, such as the curved surface of a meningeal membrane. The use of the graft product can have improved properties, including suture retention strength and fluid impermeability. To use the dural graft product as an implant to replace, reinforce or strengthen bodily tissue, or to act as an adhesion barrier, the dural graft is placed in contact with bodily tissue and conforms to the curvature of the bodily tissue. Sutures can be used to maintain the contact between the dural graft and the bodily tissue.

    摘要: A dural graft is provided having improved stiffness characteristics relative to conventional dural substitutes. The dural graft can be formed from a collagen material having a stiffness between about 0.1 pounds per inch (lb./in.) and 0.25 lb./in. Relative to the collagen material forming conventional dural graft substitutes, the decreased stiffness of the collagen material of the present dural graft can provide the graft with a relatively improved or increased pliability. As a result of the increased pliability, the dural graft can sufficiently conform to a curvature of a tissue surface to which it is applied, such as the curved surface of a meningeal membrane. The reduced stiffness of the collagen material can also provide for a relatively improved or increased flexibility or elasticity of the dural graft. The increased flexibility of the dural graft minimizes tearing of the graft when handled or manipulated during an implantation procedure.

    摘要: Flowable graft materials are provided which comprise collagen powder and a liquid in an amount sufficient to impart a flowable consistency to the material. The graft materials are sufficiently formable and pliable so as to provide both superior contact with and easier access to a surgical site than typical, more rigid grafts such as collagen sheets. These flowable materials may also be in a fluidized, paste-like and/or gel-like state and may be moldable and/or ejectable. The flowable collagen materials reduce and/or eliminate post implantation problems associated with other materials, e.g. synthetic dural sealants (hemostasis products), such as product swelling after application and implantation. The flowable graft materials are particularly useful as a dural graft.
