Transport System​

The Paragonix SherpaPak™ Cardiac Transport System is intended to be used for the static hypothermic preservation of hearts during transportation and eventual transplantation into a recipient using cold storage solutions indicated for use with the heart. The intended organ storage time for the Paragonix SherpaPak™ Cardiac Transport System is up to 4 hours.

Donor hearts exceeding clinically accepted static hypothermic preservation times should be evaluated by the transplant surgeon to determine transplantability in accordance with accepted clinical guidelines and in the best medical interest of the intended recipient.

Please review the instructions for use for complete prescribing information including indications, contraindications, warnings and precautions.

Clinical Experience

"Heart transplantation has been around for over 50 years now....[and] it’s time to be a little more scientific about how we do this. "

Dr. David D’Alessandro Cardiothoracic Surgeon
Massachusetts General Hospital
ISHLT Annual Meeting, April 4, 2019

"Definitely a game-changer. The hearts are different when they come back. They are soft, not frozen, not stiff."

Dr. Jonathan Philpott Cardiothoracic Surgeon
