A blood pump apparatus can include a pump housing having a drive chamber containing a drive mechanism. A cupped member can be connected to the housing and the drive mechanism can include a motor for rotating an eccentric shaft. A pumping arm can be provided having one end riding on the eccentric shaft, an intermediate portion pivotably attached to the housing and another end connected to a movable plate. A roller bearing can be mounted on the eccentric shaft on which the arm can ride. A compressible blood chamber having an inlet and an outlet connected can be provided sandwiched between the cupped portion and the movable plate. The motor thus rotates the cam causing the pumping arm to pivot which cycles the movable plate against the blood chamber to pump blood. The movable plate can be implanted adjacent a lung such that the lung moves with the plate as blood is pumped and thereby functions as a compliance chamber. A speed reducer can be provided between the motor and the eccentric shaft.

An implant having an integrally-textured, hemocompatible blood-contacting surface and a method for producing the same is provided. The implantable device can include a device body having a textured surface and a predefined complex shape, such as a bladder or a generally U-shaped conduit. The device body can be composed of a first device material, and the textured surface can be formed of a second device material on the obverse side of the device. The textured surface can have multiple, blood-compatible structures integrally formed thereon. The structures can be fibrils that are suitable for a generally uniform biological layer to be established thereupon. The method for producing an implantable device can include the steps of fabricating a mold; applying a flock to the mold; introducing a conformable dissoluble material to the mold; removing the dissoluble material from the mold; removing the flock from the dissoluble material using a first solvent thereby creating a dissoluble device form having a form surface having multiple invaginations therein; applying a layer of a selected device material to the dissoluble device form thereby providing a device wall with the structures being integrally formed thereon; and removing the dissoluble device form from the device wall by liquefying the device form, thereby providing the implantable device.
