RENASYS Negative Pressure Wound Therapy System

Powerfully simple

Effective, easy-to-use negative pressure wound therapy (NPWT)

RENASYS System addresses the increasing clinical need for traditional negative pressure wound therapy (tNPWT) with an intuitive, one-device solution for continuous or variable intermittent therapy across a wide range of acute, chronic and surgical wound types.1,2 RENASYS TOUCH tNPWT is uncomplicated and easy-to-learn with proven clinical performance.1-3

With the prevalence of wounds growing, 39% of which are unlikely to heal within a year,*4 the demand for tNPWT is growing where budgets are not. RENASYS tNPWT has been shown to deliver clinical benefits while supporting cost-effectiveness, compared to conventional wound therapy.4


One device for all wound care settings

Optimises clinical outcomes, without the complexity


Clinical efficacy: RENASYS TOUCH tNPWT has demonstrated a 55% reduction in wound area, an 80% reduction in wound volume, and a 20% increase in healthy, viable tissue.**1

Easy to learn: Due to the Intuitive touchscreen and interface, 97% of clinicians found RENASYS TOUCH easy to set up and over 90% were satisfied with the device functionality.1

Versatile, individualised therapy: RENASYS TOUCH tNPWT provides an adjustable compression rate which allows clinicians to tailor therapy to individual patient needs and comfort.1

High patient satisfaction: Small, lightweight and portable, with 91% of patients reporting RENASYS TOUCH tNPWT as comfortable.1,5

Watch: Wound management with adjustable or intermittent NPWT

Why use negative pressure wound therapy?

The need for NPWT is estimated to grow, with annual acute and chronic wound prevalence estimated to be 9% and 12% respectively,4 so we’re always aiming to make solutions more cost-effective. It’s important to understand the clinical benefits NPWT can provide:

  • Stimulates development of granulation tissue formation8-11 and helps reduce oedema in partial thickness burns12,13
  • Promotes moisture balance in the wound bed8, 10, 12,13
  • Removes exudate from the wound site1,14 and assists wound contraction13,14
  • Helps to increase vascular perfusion15,16 and promotes proliferation of epithelial cells.6 May decrease dressing changes compared to standard care by promoting drainage management1,8


Clinical results driven by technology


The PICO Single Use Negative Pressure Wound Therapy System provides fully portable single-use NPWT for up to 14 days.***19,20 Recommended in best practice guidelines for high-risk patients on closed surgical incisions by the UK’s National Institute for Health and Care Excellence (NICE).21

For wound infection, the RENASYS System can be used with ACTICOAT Antimicrobial Barrier Dressings with nanocrystalline silver technology.
