    Abstract: A prosthetic implant comprising a head having a spherical pyrocarbon shell (13,73) that is attached to a metal substructure (17,77) via an intermediate element (15,45,75). A subassembly of the intermediate element and the pyrocarbon shell may be connected to the metal substructure via a metal split ring (19) that resides partially in each of two facing grooves (33,35) or via interengaging elements (85,87,91) that are provided in two juxtaposed cylindrical surfaces. The design is such that compressive forces applied to the implant at its spherical articulating surface are transferred via compression through the pyrocarbon shell to the metal substructure.

    Abstract: A joint prosthesis for replacement of the metacarpal-phalangeal (MP) joint (19) of a human finger which includes a metacarpal element (13) with a stem (15) for reception into the medullary cavity of the metacarpal bone (11) and a generally ball-shaped articular head (17) and a phalangeal element (14) with a stem (16) for reception into the medullary cavity of the proximal phalangeal bone (12) and a generally socket-shaped head (18) which conforms to the ball-shaped head (17). The metacarpal element (13)'s articular head (17) has reliefs (51,52) located on each of its two lateral sides so as to provide a generally free path for the collateral ligaments (43,44). The phalangeal element (14)'s articular head (18) has a dorsal protrusion (71) that resists subluxation-dislocation of the phalangeal bone (12) and grooves (31,32) in its concave surface (22) which allow biological fluids access to the inner regions of the articulation contact surfaces (21,22). The proximal face of the head (18) may be tangent to a plane (P), or the face of the head (118) may be tangent to a cylinder of circular cross section to provide greater capture and joint stability.

    Abstract: Suture rings are provided for heart valves having surrounding stiffening protrusions that are either integral parts of the heart valve bodies or are rigid rings held in interference fit within peripheral grooves of heart valve bodies. Metal retainer rings engage the stiffening protrusions to lock the retainer rings to the valve bodies and carry fabric coverings on their exterior surfaces that are suturable to the heart tissues. Deformable portions of the retainer rings are used to provide engagement between the retainer rings and the protrusions and also to permanently position bands that secure the fabric coverings to the retainer rings.

    Abstract: Double-leaflet heart valves having improved flow through the orifice defined by an annular valve body include a pair of leaflets which may be arcuate or flat in cross section. Guides protrude oppositely from the leaflets and are received in complementary depressions in the interior wall surface of a pair of standards which extend downstream from the annular valve body at generally diametrically opposite locations. The depressions are preferably elongated so that, as the leaflets pivot between the open and closed positions, the guides move from one end of the elongated depressions to the other. Eccentric pivot axes provide for quick response of the leaflets, and the location of the depressions in the standards moves the leaflets out of the annular valve body, reducing resistance to the free flow of blood therethrough.

    Abstract: An orthopedic prosthetic implant comprises a metal alloy stem element (13, 63, 113), which has one end portion (19, 69, 119) constructed to reside in the medullary cavity of a bone and an integral connector (23, 73, 123) at the opposite end to which crystalline brittle head (17, 67, 117), preferably made of pyrocarbon-coated graphite, is joined. The head interfaces with human bone, and its effective joinder to the stem element is achieved through a polymeric insert (15, 65, 115) of proportional shape and design which has selected elastic properties. The design and material of the polymeric insert allow it to be securely received within an interior cavity (35, 77, 131) of the pyrocarbon-coated graphite head and mated to the stem connector in an either rigidly or bi-polar arrangement. The method of joinder allows the construction of composite implants that utilize the most desirable properties of metallic and brittle crystalline materials.
