摘要： A valve including a living hinge coupling a leaflet to a valve body. The leaflet can be coupled through the living hinge to the valve body's inner diameter, its outer diameter, or somewhere between the two diameters. Because the living hinge design of the valve is an integrated part, it can be manufactured in a single step.

摘要： An implantable attaching device includes an annular ring having an axial passageway and a plurality of channels extending radially through the ring. Tissue attaching pins are positioned in the channels and extend radially inward into the axial passageway during implantation. The pins are driven into the native annulus tissue after the ring is positioned. Once the pins are driven into the annulus, the axial passageway of the ring is unobstructed and is adapted to receive a heart valve or other implantable device.

摘要： A system and method are disclosed for implanting a medical device (12) into a body. The medical device (12) has an expanded state and a collapsed state and is inserted into the body while in the collapsed state. The medical device (12) is positioned proximate a desired implant site (14) in the body, and the medical device (12) is expanded to the expanded state by filling the medical device (12) with a hardenable fluid (18). The hardenable fluid (18) is then hardened such that the medical device (12) is set in the expanded state at the desired implant site (14).

摘要： A fluidized bed apparatus which produces a pyrolitic carbon coating with improved wear and porosity characteristics of the coating by producing a more uniform flat temperature profile throughout a reaction chamber in the area where coating is taking place. The apparatus has heating coils surrounding a lower end of the reaction chamber placed immediately adjacent one another at tight spacing. This contrasts to previous apparatus wherein heating coils were spaced between 2 cm and 5 cm apart. The apparatus also has a multi-jet nozzle to control a flow of gases through the reaction chamber. The jets in the nozzle comprise passages which are oriented such that the length of the passages lie on a series of cones having common axes.

摘要： A bi-leaflet heart valve having an annular body and a pair of leaflets. The leaflets pivot around improved ears, whose motion is constrained by generally triangular recesses. The triangular recesses have a pivotal vertex in proximity to a centerline of the annular base and on the upstream side of the heart valve. Opposite the pivotal vertex is a slightly concave base. An upstream wall of the recess is convex.

摘要： A combined mechanical heart valve and vascular graft having a shortened transition area between the valve and the graft. The mechanical valve comprises a rigid circular annulus supporting internal leaflets. A stiffening ring surrounds the annulus and provides support for a sewing ring to attach the valve to the heart. The stiffening ring also captures a proximal end of the vascular graft between the stiffening ring and the annulus.

摘要： Fluidized bed apparatus for use in applying a coating, having a relatively lesser density to particles, having relatively greater densities, by causing passage of a gaseous atmosphere through a bed of the particles. The apparatus includes an enclosure for holding and heating a bed of the particles. A valve network for causing the flow of the gaseous atmosphere carrying a material for forming the coating upward though the bed of particles to fluidize the particles, is provided. The apparatus further includes a conveyor for adding seed particles to the bed and a spillover for removing particles from the bed upon its achieving a predetermined level to limit the height of the bed. The apparatus also has a selectively operable sampler for removing sample of the contents of the bed at a level below the predetermined maximum level.

摘要： A support ring for a natural human heart valve includes a first ring portion having opposite terminal ends and a second ring portion having opposite terminal ends. An interconnector extends through and interconnects the first and second ring portions, to maintain the opposite terminal ends of the first ring portion adjacent the opposite terminal ends of the second ring portion, to form a segmented ring having a first and a second interface between the first and second ring portions. The first ring portion is of a greater length than the second ring portion. The ring portions are separable by severing the interconnector at the first and second interfaces, thus producing two variable size ring segments.

摘要： A heart valve prosthesis rotator having a flexible drive for flexibly turning a heart valve. One embodiment has a shaft constructed from elastically deformable metal alloy such as super elastic nickel-titanium alloy. Another embodiment has a shaft constructed of surgical tubing. Yet another embodiment also has an annealed stainless steel shaft which can be bent by the surgeon interoperatively. The shaft will retain its shape after bending. Surrounding the shaft is a drive coil which connects a rotator head at a proximal end of the shaft to a drive knob at a distal end of the shaft and adjacent a handle. By turning the drive knob, a surgeon can turn the rotator head, thus orienting the prosthetic heart valve. Torsional motion is carried along the path defined by the bendable shaft so that the rotator head can be turned without displacing the handle of the heart valve rotator.
