Abstract
Methods, system and compositions for making and using a bioresorbable linked dressing made of bioresorbable microspheres in various configurations are provided for use in applying reduced pressure to a wound site. The methods include manufacture of a bioresorbable dressing comprising a casing and bioresorbable microspheres in the form of a rope shape. Further, the casing of the dressing comprises pores formed by a porogen system that may be activated by external to the wound or formed in situ within the wound site. The shape of the dressing allows the dressing to be placed into the wound site such that it fills the shape and size of the wound. Embodiments include formation of various rope dressing and their use in conjunction with reduced pressure therapy.
