Further study details as provided by Nonin Medical, Inc:

Primary Outcome Measures:
  • Evaluate brain tissue oxygenation assessing the number and percentage of subjects from whom regional data could be collected during 90% of the aortic arch surgery, and the registration rate during deep hypothermic circulatory arrest. [ Time Frame: At the end of the surgical case approximately 6 to 8 hours ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Determine whether there are unilateral or global differences in cerebral tissue oxygenation detected during selective antegrade cerebral perfusion [ Time Frame: At the end of the surgical case approximately 6 to 8 hours ] [ Designated as safety issue: No ]

Enrollment: 20
