摘要： Compressors are provided which include a motor having a drive shaft; a compression chamber, having an inlet and an outlet; a diaphragm, disposed within the compression chamber such that when the diaphragm is deflected back and forth between a first position and a second position air is drawn in through the inlet and forced out through the outlet; a crankshaft, operatively connected to the drive shaft; a shuttle, configured to be displaced transversely by rotational movement of the crankshaft, and positioned to deflect the diaphragm by its transverse movement; and a guide configured to inhibit non-transverse motion of the shuttle. In some implementations, the compressor occupies a total volume of less than about 15 cubic inches.

摘要： A ventricular apex connector for quick connection and disconnection of an inflow tube of a ventricular assist device, comprising a sewing ring, a cylindrical ring, gripping pins, a spring ring and a sealing O-ring is provided. The cylindrical ring defines two openings, diametrically opposed to each other, in its walls. Gripping pins, comprising rods with gripping pads, are placed in the openings in the cylindrical ring so that the gripping pads are at rest within the inner circumference of the cylindrical ring. The spring ring is placed around the cylindrical ring and the rods of the gripping pads, which extend out of the outer wall of the cylindrical ring, are welded to the spring ring. The gripping pins are thus biased towards each other by the force of the spring ring. When the spring ring is squeezed, at points away from the gripping pin connection points, the deformation of the spring ring causes the gripping pads to be pulled out towards the inner wall of the cylindrical ring. An inflow tube of a heart pump may then be inserted into the ventricular apex connector, and upon the release of the spring ring, the inflow tube is sealedly held within the ventricle of the heart. In an embodiment an adapter sleeve may be attached to the inflow tube. In a further embodiment, the inflow tube may include an inner sleeve that is slidably and rotatably mounted therein. The inflow tube may have a bend at an end.

摘要： A blood pump is provided which comprises a cross-flow pump head having an elongated generally cylindrical housing portion. The housing portion defines a blood inlet port on a surface thereof and a blood outlet port on an opposite surface thereof. An impeller within the housing portion provides cross-flow of the blood from the inlet port around and/or across the rotational axis of the impeller to the outlet, and a motor is provided for driving the cross-flow pump head. The blood pump may be small enough to permit percutaneous insertion of the pump into a patient's blood vessel, and thus may be utilizable as a left ventricular assist device. To this end, a collapsible polymeric outflow tube is coupled to the blood flow outlet and is adapted for directing the blood from the left ventricle to the aorta through the aortic valve.
