Giving transplant patients every possible advantage


Advancing the Science of Preservation

Paragonix is committed to improving the science and understanding of organ preservation and is leading the novel GUARDIAN Study to enhance understanding of the impact of advanced preservation.

The GUARDIAN Study is a post-market, observational registry containing both retrospectively and prospectively collected patient outcomes data. The GUARDIAN registry currently contains data from over 400 enrolled patients from 8 transplant centers.

Physicians from around the world are publishing their experiences with advanced preservation in clinical research journals.

Impact Multiple Stages of The Transplant Process

Figures represent the percentage difference observed between transplant recipients of donor hearts preserved by Paragonix SherpaPak®  CTS and ice storage, as reported in the GUARDIAN registry. These results are based on analysis of the first 223 patients (99 ice transports and 124 Paragonix SherpaPak CTS transports) enrolled in GUARDIAN across 5 transplant centers.


New Procurement Consensus

New consensus statement from the International Society for Heart and Lung Transplantation calls for strategies to avoid close proximity to ice because of irreversible cellular damage and graft failure.3

Paragonix SherpaPak®  CTS helps users confirm achievement of ISHLT Donor Heart and Lung Procurement Consensus Statement preservation goals:
  • Physically & thermally isolate with rigid, sterile container
  • Temperature maintenance at above freezing risk point
  • Measure and record to confirm correct storage
