title: The AB-180 circulatory support system: summary of development and plans for phase I clinical trial.
abstract: BACKGROUND
  The AB-180 circulatory support system is a small, durable, efficient centrifugal pump with low thrombogenic potential. The device was designed to provide a fully implantable, left ventricular assist system for short-term support to address the issues of systemic anticoagulation, thrombus formation, infection, and cost.
  
  
  METHODS
  Extensive bench and animal studies were performed to validate the mechanical integrity of the device and its functionality as an implant.
  
  
  RESULTS
  These studies demonstrated anticoagulation requirements, established operating guidelines, incorporated safety systems, and demonstrated safety and efficacy.
  
  
  CONCLUSIONS
  The AB-180 fulfills the stated goals on initial evaluation. A phase I human trial is underway.
