| 摘要 |
The present invention provides wound healing or wound care polymer compositions that can be formulated to release a wound healing agent at a controlled rate by adjusting the various components of the composition. The compositiona can be used in an external wound dressing, as a polymer implant for delivery of the wound healing agent to an internal body site, or as a coating on the surface of an implantable surgical device to deliver wound healing agents that are dispersed in a biodegradable polymer or hydrogel, or both. Methods of using the invention bioactive polymer compositions to deliver wound healing agents that promote natural healing of wounds, especially chronic wounds, are also provided. |
