Implantable medical articles comprising natural biodegradable polysaccharides are described. The polysaccharides can provide desirable release properties, and can also be degraded into products that can act as an excipient in the presence of the bioactive agent. In some aspects, the articles are ocular implants formed of a matrix of natural biodegradable polysaccharides. These ocular implants include a bioactive agent that can be released within the eye to treat an ocular condition or indication.
