DeBakey By-Pass Pump

DeBakey By-Pass Pump

<< >>
Usage conditions apply
The DeBakey paracorporeal left ventricular assist device was developed by scientists at Baylor and Rice Universities. The pump is gas generated and is made with Dacron reinforced with Salastic. A diaphragm separates the gas chamber from the blood chamber.
This example was developed by Dr. Michael DeBakey (1908-2008) in the mid-1960's. The pump lies outside the body, one tube is inserted into the left atrium, and a second tube goes into the right auxiliary artery. DeBakey reported on three cases using this pump in a 1971 article "Left Ventricular Bypass Pump for Cardiac Assistance" in The American Journal of Cardiology.
This pump is a direct descendant of an earlier by-pass pump developed in DeBakey’s laboratory. See Accession 256189.01.
