Beschreibung
Zusammenfassung:	A diaphragm assembly for a pulsatile fluid pump includes an edge-mounted flexible diaphragm, the diaphragm configured for operation cyclically between a diastole mode and a systole mode. The diaphragm assembly further includes a systolic distribution brace having an interior wall configured to cup a portion of the outside surface of the diaphragm, and a diastolic plate, embedded in the diaphragm, mechanically coupled to a portion of the inside surface of the diaphragm. In the course of the systole mode, force is applied across the maximum radial extent of the systolic distribution brace, so as to impart tension in the diaphragm around the periphery of the systolic distribution brace. In the course of the diastole mode, force is applied across the maximum radial extent of the diastolic plate, so as to impart tension in the diaphragm around the diastolic plate.
