PEGylated carboxyhemoglobin bovine (SANGUINATE) ameliorates myocardial infarction in a rat model.

abstract：:The VentrAssist pump has no shaft or seal, and the device is unique in design because the rotor is suspended passively by hydrodynamic forces, and urging is accomplished by an integrated direct current motor rotor that also acts as the pump impeller. This device has led to many challenges in its fluidic design, namely...
