    摘要: A pump has an elongated shell with a generally elliptical shape, an outer convex surface and an inner concave surface. A peripheral side edge located between the inner and outer surfaces terminates in a bead edge. A flexible airtight membrane has a membrane edge bonded to the outer shell surface adjacent to the bead edge. Preforming the membrane edge looped with a maximum linear span of curvature that is greater than a maximal transverse linear extent of the bead edge, membrane operational wear during inflation and deflation cycles is reduced in the region around the bead edge. A process of forming a blood pump with a membrane preform is also provided.

    摘要: An implantable aortic blood pump includes a rigid body having wall extending along a long axis and defining an inflation port portion with an inflation aperture therethrough. The aperture is fluid communication with an inner surface of the body and on a fluid supply, the body is preferably independent of an external brace or an external stiffener, yet still has a cantilevered deformation of less than 8 millimeters in response to a 200 gram weight suspended from a front body edge. A deflecting structure of a membrane deflects in response to fluid pressure so as to pump blood when the pump is secured to a subject aorta.

    摘要: A drive unit to control the peak pressure of air for the inflation of a left ventricular assist system is disclosed. The control of the peak pressure can address the problem of the “kick” experienced by patients when the peak inflation pressure reaches approximately 200 mm Hg. The peak pressure of the air released for the inflation cycle of the system is reduced either by the reduction of the inner diameter of the interconnect line running from the compression tank to the valve manifold or the use of a multi-valve manifold with independently controlled valves and an electronic controller to selectively open and close the valves of the manifold. Either technique, whether used alone or in combination, reduces the peak pressure of the air released for the inflation cycle to below the levels associated with the “kick,” while still meeting the operating specifications to properly inflate and deflate the system's blood pump.

    摘要: A high throughput sputtering apparatus which provides a single or multi-layer coating to the surface of a plurality of substrates. The apparatus comprises a plurality of buffer and sputtering chambers which include an input end and an output end. The substrates are transported through the chambers at varying rates of speed such that the rate of speed of a pallet from the input end to the output end is a constant for each of the pallets. The high throughput sputtering apparatus also includes a transport system which transports the substrates through the sputtering chambers at variable velocities, a high capacity vacuum pump system which evacuates the ambient pressure within the sputtering chambers to a vacuum level within a pressure range sufficient to enable sputtering operation, a substrate heating system which heats the substrates to a temperature conducive to sputtering the coatings thereon and provides a substantially uniform temperature profile over the surface of the substrates; and an electronic control system which provides control signals to and for receiving feedback input from other components of the apparatus. The electronic control system is programmable to control the sputtering chambers, the transport system, the vacuum pump system, and the substrate heating system. The substrate heating system efficiently maintains a desired substrate temperature by minimizing radiative heat losses as the substrates proceed through the sputtering apparatus. The high throughput sputtering apparatus provides substrates to be sputtered in a rapid and uniform heating process to optimize film integrity during the sputtering steps, provides successive layers of thin films on the substrates, and removes the sputtered substrates without contaminating the environment.
