  • Fewer cognitive and neurological effects (for example, a stroke)
  • Less risk of problems with memory
  • Faster recovery rates
  • Shorter hospital stays
  • Fewer blood transfusions needed

Clampless Beating Heart Surgery (OPCAB)

The HEARTSTRING Aortic Cutter creates a precision aortotomy during clampless beating heart surgery (OPCAB). The clampless approach to cardiac surgery can reduce the risk of complications in patients with diabetes, history of stroke or poor physical health.

Steps to create the aortotomy

  • Remove protective cap from Aortic Cutter and release the Safety Lock
  • Support body of Aortic Cutter as if deploying a syringe-like instrument
  • Place Aortic Stop flush with the aortic surface, perpendicular to the aorta
  • Depress the Actuation Button (an audible sound will indicate deployment)
  • Remove Aortic Cutter and place finger over hole to maintain hemostasis prior to Seal deployment
