New Data Demonstrates That Medela’s Invia System Delivers Positive Patient Outcomes & Outperforms Other Negative Pressure Wound Therapy (NPWT) Systems

Findings Reveal Invia® LibertyTM Provides More Accurate Pressure Delivery

McHenry, IL, April 21, 2022 (GLOBE NEWSWIRE) -- McHenry, Ill., April 21, 2022 – Medela LLC today announced the release of new data in five blind-reviewed SAWC Spring published posters and white paper supplement to WOUNDS that each demonstrate how the Medela Invia Liberty Negative Pressure Wound Therapy (NPWT) System delivers positive patient outcomes and outperforms other NPWT systems in the market. These publications reinforce that Medela’s patented Intelligent Pressure Control™ and Dynamic Exudate Removal™ technology delivers the prescribed pressure more consistently and accurately, while dynamically responding to changing wound fluid conditions; essential to delivering effective therapy and maximizing clinical effectiveness.    

“After rigorous evaluation, the Medela Invia System has had an incredible impact on our ability to provide exceptional patient care,” states poster author Keri Mullins, RN, BSN, chief clinical officer for North Alabama Specialty Hospital. “Though we had no plans to convert from our previous system, the Invia System not only met our high clinical standards, now our team spends less time problem solving, which has led to high staff and patient satisfaction, and our NPWT budget was initially reduced by 68% and has stayed low for the second year in a row. I would do this again even without the savings to increase our patient and staff satisfaction.” 1

The newly published white paper data demonstrates how the Medela Invia Liberty NPWT System outperforms Renasys™ Touch (Smith + Nephew) by dynamically responding to sudden changes in exudate volume while maintaining consistent pressure. 2 The positive results of this study coincide with findings from two previous studies also presented at SAWC Spring using the same testing methods, which show Invia’s superior performance when compared to V.A.C.™ Ulta (3M™) and CATALYST™ (Cardinal Health™), two other systems in the market. 3, 4 Together, these studies reveal that by being able to dynamically adapt to changes in fluid volume or viscosity, the Invia System outperforms others in the market, which maximizes patient healing potential.  

“The challenges associated with chronic wound care was exacerbated by the global pandemic with patients delaying primary care and wound clinician visits to reduce exposure to the virus, which had significant impact on wound severity for some patients,” 5 explains Jeff Castillo, executive vice president of the Americas for Medela. “With our Invia Systems, Medela is elevating the standard of care through our exclusive Intelligent Pressure Control and Dynamic Exudate Removal technology and innovating the way NPWT is delivered at the wound bed. We are honored to advance care to encourage patient healing and recovery.”  

Medela’s comprehensive support to clinicians and patients using the Invia Liberty and Invia Motion® NPWT Systems includes access to “how-to” video resources and instructions for set up and operation through the free Medela NPWT app and online, 24/7 clinical and technical support, and Medela University, an online resource providing professionals with access to on-demand continuing education.
