Glutaraldehyde Fixation vs. Photo-Fixation

Unlike glutaraldehyde treated tissue, PhotoFix tissue uses dye-mediated photo-oxidation to crosslink and stabilize the internal collagen structure - eliminating toxic by-products that create sites where calcium can bind to tissue.1-4

PhotoFix is nonimmunogenic, biocompatible, non-cytotoxic, and maintains natural physical properties and biomechanical integrity.5

THE CLINICAL STORY

Use of PhotoFix in Congenital Cardiac Surgery at Boston Children's Hospital6

  • 490 patches used between 2008 and 2011 in 364 patients (median age 5.3 years).
  • Mean late follow-up of 3.2±1.6 years.
  • Demonstrated excellent performance in cardiovascular repair in children.
  • Wide range of applications show consistent handling characteristics and biocompatibility.
  • Eight patch specimens were available for histological analysis (up to 72 months):
    • “Inflammation was absent or minimal in 6 cases and mild in 2 others.”6
    • “No calcification noted in 5 cases, mild calcification in 2 cases and at least moderate calcification in 
      1 case.”6

PhotoFix Actuarial Survival

Review of clinical and pathology database of patches used in cardiac surgery at one children's hospital noted:7

  • PhotoFix used in locations exposed to lower stresses showed little or no calcification.
  • Calcification did not differ significantly between PhotoFix and autologous pericardium in multiple intracardiac applications.
  • The grades of neointima formation did not demonstrate a significant difference between PhotoFix and autologous pericardium.

Endothelial Cell Monolayers on Photooxidized Material

Animal studies have shown:

  • There was no evidence of collagen degradation, thrombogenicity, infection, excessive inflammation or intrinsic calcification in sheep animal models (140 days).8
  • PhotoFix process has demonstrated no significant calcification in both subcutaneous rat (60 days) implants and juvenile sheep (140 days) animal models.8
  • Endothelial cell growth is supported in vitro by photooxidized pericardium and vascular grafts (Figure 2).5
