Dry powders containing bioresorbable hyaluraonic acid ("HA") are applied directly to a desired location in a patient wound to reduce adhesions, without first forming a hydrated gel. HA includes hyaluronic acid that has been modified, cross- linked or combined with other substances. It is important to control the size of the particles in the powder. The powder is essentially dry and blowable powder. At least 90 % of powder particles have a maximum dimension between 30mum and 1mm. ® KIPO & WIPO 2007 |
