S&N markets Renasys NPWT and Versajet hydrosurgery systems in Japan

Smith & Nephew (S&N) has introduced the Renasys negative pressure wound therapy (NPWT) and Versajet hydrosurgery systems in Japan. Both systems were approved by the country's Ministry of Health Labour and Welfare in July 2012 and complement S&N's range of integrated wound management products available in the country.

The Renasys NPWT system is designed to offer enhanced wound healing and improved patient comfort in traumatic and other hard-to-heal wounds while providing a portfolio range to allow clinicians to use their full clinical judgement in treating each individual patient. The portfolio includes two different pump options, which offer flexibility in treating a wide variety of wounds in various care settings. The two alternative dressing technologies also allow clinician choice to meet the individual needs of the patient and their wound.

A comprehensive clinical study of 80 patients was conducted on Renasys in Japan. The study, which looked at the safety and efficacy of Renasys, took place over 16 centres with various acute, sub-acute and chronic wounds. The overall data endpoints were similar to those in overseas literature and a NPWT study previously conducted in the country. In addition to the clinical endpoints - foam and cotton fillers were evaluated and found to have with a usage pattern suggesting specific benefits of wound fillers to certain wound types. This again was similar to overseas experience in NPWT.

The Versajet system allows clinicians to precisely select, excise and evacuate necrotic (damaged or dead) tissue, bacteria and contaminants from wounds, burns and soft-tissue injuries using an ultra-thin saline jet that spares viable tissue and optimises surgical debridement. It can potentially decrease the time to wound closure and the overall treatment costs. In a clinical study conducted with Versajet on 47 patients with a range of burns, acute and chronic wounds across six centres in Japan, 94 per cent of patients achieved appropriate debridement following a single debridement procedure, as verified by an independent photographic assessment. It was found that 91 per cent of wounds did not progress into a deeper compartment, indicating a high degree of tissue preservation.
