LivaNova Sorin Stockert 3T

Sorin Stockert 3T Perfusion System

The Sorin Stockert 3T Perfusion System is a heater-cooler unit designed for use during cardiopulmonary bypass, cardiac, vascular, and transplant procedures. This advanced system regulates blood temperature through conductive heat transfer without directly contacting the patient’s blood. It features three separate water tanks—each operating on its own circuit—to independently control warming and cooling for cardioplegia and patient temperature management. The system also allows for easy drainage at the end of procedures, simplifying cleanup.

Key Features

• Rapid Pre-Cooling:
  • Provides short pre-cooling times for quick setup before procedures.
• Dual Water Tanks for Warming & Cooling:
  • Two small volume tanks control the warming and cooling cardioplegia, while a third tank manages patient temperature.
• Independent Safety Systems:
  • Equipped with an independent safety system to prevent water temperature from reaching critical levels.
  • Two-chamber pumps minimize pressure inside the heating chamber.
• Efficient Emptying:
  • Suction capability enables smooth emptying of the heating chamber and tubing at the end of a procedure.
• User-Friendly Operation:
  • At the end of a procedure, the water is easily drained out of the heat exchanger, streamlining the cleanup process.
