Delivering a New Standard in Heart Preservation
Traditionally, donor hearts destined for transplantation were placed into commercial-grade coolers filled with ice to transport it to the recipient. This method presents a multitude of uncontrolled variables that can impact the function of the heart post-transplant. Clinical evidence has shown that ice transport can expose the donor heart to freezing temperatures, leading to irreversible cellular damage.1

The Paragonix SherpaPak CTS is an Advanced Organ Preservation device specifically designed to standardize the variables of donor heart preservation, providing physicians with stable cooling technology driven by real-time data monitoring.
Caution: Federal (US) law restricts this device to sale by or an the order of a licensed health care practitioner. Please refer to Instructions for Use for full prescribing information. Cleared indication is for 4 hour use. Patents issued and pending. See legal page for more information.
Technological Advantage of Advanced Organ Preservation
Traditional Ice Storage
  • Uses commercial-grade coolers unregulated by the FDA
  • Packs heart in layered plastic bags filled with cold liquid solution
  • Exposes cold liquid solutions - and the donor heart - to an environment of 0°C ice
  • Unpredictable temperature reductions within the ice cooler are not monitored during transport
SherpaPak CTS
  • An FDA-cleared and CE-marked preservation device intended to protect the donor heart in transit
  • Suspends heart in an isolated, pressure-controlled canister of cold liquid solution
  • Utilizes SherpaCool® phase-change technology to prevent exposure to excessive temperature reduction
  • Records temperature, location, and case status in real-time
Offering a controlled approach designed for ease-of-use in a clinical setting.
Key Features
Temperature Probe
Internal probe continuously monitors and records the internal and ambient temperatures
Heart Connector
Interchangeable heart connector fully suspend adult and pediatric hearts in cold preservation solution
Nested Canister System
Pressure-controlled, leak-proof rigid canister safeguards and cools the heart evenly
SherpaCool Technology
Proprietary phase-change cooling formula that maintains optimal temperature conditions without the use of 0°C ice
Rigid Outer Shell
Protective polystyrene material ensures internal environment will maintain temperature
Monitor and Data Transmission
Simple Bluetooth® pairing allows the system to transmit full data reports to as many users as necessary
Clinical Findings and Research
To measure the clinical impact of advanced organ preservation, Paragonix leads the novel GUARDIAN-Heart Clinical Registry. Our panel of clinical investigators analyze the post-transplant outcomes of the SherpaPak CTS in comparison to traditional ice storage.

A 1-year propensity-matched analysis was recently published in 2022, showcasing that the transplant recipients in the SherpaPak CTS cohort experienced more positive outcomes than those in the traditional ice storage cohort.2,3

Important Safety Information

Indications for Use
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.
The Paragonix SherpaPak Cardiac Transport System should not be used in the following circumstances: When safe connection with the aorta cannot be made, e.g., due to lack of enough length of the aortic root.
Caution: Donor hearts exceeding 4 hours static hypothermic preservation time will require transplant surgeon evaluation to determine transplantability.
