1 Preclinical readiness testing of the arrow international CorAide left ventricular assist system 
Kazuyoshi Doi, MD, Leonard A.R Golding, MD, Alex L Massiello, MEBME, Michael W Kopcak, BA, Renee L Gerhart, BSBME, Soren Schenk, MD, Masahiro Inoue, MD, PhD, Yoshio Ootaki, MD, PhD, Kiyotaka Fukamachi, MD, PhD  The Annals of Thoracic Surgery  Volume 77, Issue 6, Pages (June 2004) DOI: /j.athoracsur

2 Fig 1 Schematic of blood-lubricated fluid film bearing of the CorAide pump. The secondary flow path washes the bearing surfaces and supports the rotating assembly, preventing mechanical contact or wear. The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur )

3 Fig 2 The Arrow CorAide left ventricular assist system implantable components. The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur )

4 Fig 3 The Arrow CorAide left ventricular assist system external components. The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur )

5 Fig 4 The relationship between measured pump flow versus calculated pump flow in case 6. The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur )

6 Fig 5 The relationship between pump speed adjustments by automatic control algorithm versus postoperative day in case 6. The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur )

7 Fig 6 Changes in hemoglobin and hematocrit of the 7 cases. *p < 0.05 versus Pre. (Pre = preoperative day.) The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur )

8 Fig 7 Changes in platelet count of the 7 cases. *p < 0.05 versus Pre. (APTT = activated partial thromboplastin time; Pre = preoperative day.) The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur )

9 Fig 8 Changes in liver function versus time of the 7 cases. *p < 0.05 versus Pre. (ALT = alanine aminotransferase; AST = aspartate aminotransferase; Pre = preoperative day; T-Bil = total bilirubin.) The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur )

10 Fig 9 Changes in serum free hemoglobin of the 7 cases. *p < 0.05 versus Pre. The normal range of serum free Hb is 0 to 5.0 mg/dL. (Hb = hemoglobin; Pre = preoperative day.) The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur )
