FibroBLOX Fibroblast Prevention Surfaces

Demonstrated Fibroblast/Tissue Prevention



PcoMed prevents various cell types from attaching to implant materials by creating the proper nano-topology and proper surface energy.


Fibroblast encapsulation is a common problem for many materials from polyurethane insulation and tubing to PEEK spinal implants.  Fibroblast encapsulation can compromize device performance (e.g. PEEK interbody devices) or make device removal very difficult (e.g. pacing leads).  PcoMed has created the FibroBLOXTM family of fibroblast prevention surfaces for various applications within the body.


Multiple PcoMed surfaces can reduce fibroblast attachment on most polymers and many other materials.

  • One PcoMed surface, TruBōn, is used by a major spinal company on its PEEK interbody devices to eliminate fibroblast formation.

  • Performance has been demonstrated in in vivo animal testing.

FibroBLOX Fibroblast Prevention Surfaces


Multiple PcoMed surfaces reduce fibroblast/tissue attachment to polymers and other materials, including those typically used on leads.

  • One such PcoMed surface is sold today on a commercial, FDA-cleared PEEK spinal implant.

  • Elimination of fibroblast encapsulation demonstrated in in vivo sheep testing.

  • Other PcoMed surfaces demonstrated in in vitro tests on polymers ranging from silicones to polyurethanes.
