Type I collagen particles: stimulates healing with high patient satisfaction and substantial reduction in health care costs. Estimates show that healing with Helisorb Particles is achieved at approximately one third the cost of preceding treatment that has failed to bring about healing.

Helisorb Particles produce excellent outcomes in wounds where standard care has failed or where the clinician assesses that standard care may not bring about desired outcomes.

How long should you wait for signs of healing before considering switching to Type I collagen?
Shehan et al 2003 showed that 4 weeks of observation is a robust predictor of healing at 12 weeks.

4 weeks may serve as a pivotal clinical decision point in the care of diabetic foot ulcers for early identification of patients who may not respond to standard care and may need additional treatment.

Helisorb Particles:

  • Are highly absorbent and create an environment conducive to healing by initiating chemotaxis of granulocytes, macrophages and fibroblasts
  • Reduces wound pH levels
  • intact Type I collagen molecules act as a scaffold for cellualr attachment
  • Remove exudate, reduce inflammation and oedema, and allow for gaseous exchange
  • Act as a natural stimulant for autolytic debridement
  • Transforms wounds from inflammation phase to remodeling phase. Rapid reduction of inflammation.


  • Chronic / non-healing wounds eg DFU
  • Dehisced surgical wounds
  • Low to high exudating wounds, infected wounds, sloughy (wet or dry) wounds
  • Cavity wounds
  • EB wounds

In chronic/non-healing wounds, Helisorb Particles effectively act as a competitive substrate for excess matrix metalloproteinase-2, matrix metalloproteinase-9, and bacterial collagenase and influences this imbalance positively.

The increased accessible surface of the particles plays a crucial factor in effectiveness.
