1 Arterial balloon catheter: a new atraumatic device for dilating arterial grafts 
Hugues Jeanmart, MD, Louis P Perrault, MD, PhD, Nathalie Desjardins, BS, Olivier Chavanon, MD, Michel Carrier, MD, James D Fonger, MD  The Annals of Thoracic Surgery  Volume 72, Issue 3, Pages (September 2001) DOI: /S (01)

2 Fig 1 Arterial balloon catheter. (A) Inflated; (B) deflated.
The Annals of Thoracic Surgery  , DOI: ( /S (01) )

3 Fig 2 Internal mammary artery increases in flow rate before and after application of 2.5- and 3.0-mm metal dilators and long and short balloon. Results are presented as: (A) increase in mL/min of flow rate, and (B) increase in percentage of flow rate compared with control. Results are presented as mean ± standard error of the mean (∗ vs short balloon, p is nonsignificant). The Annals of Thoracic Surgery  , DOI: ( /S (01) )

4 Fig 3 Cumulative concentration-response curve to arachidonic acid in rings of porcine internal mammary artery with endothelium. Responses are given as a percentage of maximal contraction (final percentage relaxation). Results are presented as mean ± standard error of the mean. The Annals of Thoracic Surgery  , DOI: ( /S (01) )

5 Fig 4 Cumulative concentration-response curve to acetylcholine in rings of porcine internal mammary artery with endothelium. Responses are given as a percentage of maximal relaxation (final percentage contraction). Results are presented as mean ± standard error of the mean. The Annals of Thoracic Surgery  , DOI: ( /S (01) )

6 Fig 5 Cumulative concentration-response curve to sodium nitroprusside in rings of porcine internal mammary artery with endothelium. Responses are given as a percentage of maximal relaxation (final percentage contraction). Results are presented as mean ± standard error of the mean. The Annals of Thoracic Surgery  , DOI: ( /S (01) )

7 Fig 6 (A) Percentage of endothelial coverage assessed by silver nitrate staining. Results are presented as mean ± standard error of the mean (∗ vs control p < 0.05; ∗∗ vs long balloon p < 0.001). (B) Representative photograph of the intact endothelial lining in the internal mammary artery after dilatation with the arterial balloon catheter. The Annals of Thoracic Surgery  , DOI: ( /S (01) )
