Porous bioresorbable rope shaped wound dressing comprising microparticles and reduced pressure source

摘要

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.

主权项

1. A system for applying reduced pressure tissue treatment to a wound site, the system comprising:
a dressing that is porous bioresorbable and comprising a rope shaped casing having microparticles inside the casing that are bioresorbable, constrictions at repeating intervals of the rope shaped casing, and having a porogen system in the casing adapted to form pores in the casing, the dressing adapted to be disposed adjacent the wound site; a drape adapted to cover the dressing and create a sealed space containing the dressing; a reduced pressure source adapted to supply reduced pressure; and a reduced pressure delivery tube adapted to be fluidly coupled between the reduced pressure source and the dressing to provide the reduced pressure to the dressing.
