OCS™ Heart

The only device currently under FDA review for utilized and unutilized donor hearts

Often referred to as a “Heart-in-a-Box”, the OCS Heart™ is a revolutionary system that preserves donor organs.

The OCS acts as a miniature intensive care unit that keeps organs alive and healthy by preserving them in a natural state that mimics the human body

so that organs can remain viable for transplant along the way to recipients.

 OCS Heart Clinical Evidence 

PROCEED II TRIAL

Randomized study for preservation of utilized donor hearts.
128 patients were enrolled worldwide
Primary effectiveness endpoint
– Patient survival at 30 days post transplant

OUTSIDE THE US

OCS Heart has been used to successfully transplant over 100 hearts from circulatory death donors

EXPAND Trial

US pivotal trial to evaluate the Organ Care System for use with unutilized donor hearts that may not meet current standard acceptance criteria for transplantation.
 • 75 patients were enrolled
 • Types of donors used
– Ischemic time >4 hours – 37%
– 20+ mins of down time – 28%
– EF of 40-50% – 23%
– LVH 13-16 mm – 23%
– Older donors >45 years – 13%
– Coronary artery disease – 7%
– 25 patients had 2+ indications
UNOS data showed donor hearts used for the OCS Heart EXPAND Trial had been declined for transplantation on average 66 times by other transplant centers before reaching an OCS Trial Center
Primary effectiveness endpoints:
– Patient survival at day-30 post transplant
– Absence of severe primary heart graft dysfunction (PGD) in the first 24 hours post-transplantation

OUTSIDE THE US

OCS heart has been used to successfully transplant over 100 hearts from circulatory death donors

OCS Heart Patient Stories

Hear from a patient who has benefited from the TransMedics OCS and discover if this may be a viable option for you or someone you know.

A heart on ice is a question mark. With an OCS heart, there is no question, it’s a viable heart. It’s ready to be implanted in the recipient.
