Knee and hip joint supplier Smith & Nephew said it is launching two extensions to the ALLEVYN Ag range of dressings; ALLEVYN Ag Gentle Border and ALLEVYN Ag Gentle. 'The addition of these two new ALLEVYN Ag variants will undoubtedly add to the growing success of ALLEVYN and will enable us to maintain our position as the leading global brand within the foam dressings market,' said Roger Teasdale, President, Smith & Nephew Advanced Wound Management. 'ALLEVYN Ag Gentle Border provides the perfect opportunity to reinforce the perception of Smith & Nephew as leading the way in woundcare as we will be the first company to offer an adhesive bordered silicone silver product which combines the benefits of silver and silicone gel technology.'Elsewhere, Optos said that Christine Soden joins the retinal imaging company on 22 September as interim chief financial officer while the search for a permanent replacement continues.
