ABSTRACT:
A bi-ventricular cardiac assist device maintains blood circulation in a patient having a minimally functioning or malfunctioning heart. The biventricular cardiac assist device includes a self-supporting cup-shaped outer shell having opposed upper and lower ends, and an inner surface which establishes an interior cavity for receiving a heart therein. The outer shell defines a pair of diametrically opposed slots oriented generally longitudinally between the upper and lower ends of the outer shell. An annular diaphragm conformably shaped to the outer shell is positioned adjacent to the outer shell's inner surface. The diaphragm most preferably includes upper and lower edges bonded to the outer shell at the upper and lower ends thereof, and a pair of diametrically opposed, generally longitudinally oriented unitary connection flange. Each connection flange is preferably generally T-shaped in cross-section and coupled to a respective one of the slots. The connection flanges are thus bonded to the outer shell so that the diaphragm defines a pair of semi-annular fluid chambers with the inner surface of said outer shell. Most preferably, all structural components, e.g., the outer shell and the diaphragm, are formed of substantially the same urea-linked polyureathane copolymer, but have different Shore A hardness values.
