ABSTRACT:
Bioresorbable medical implants are designed to have different resorption rates over time or over the topography of the implants. The resorption of the medical implants are controlled by including layers having differing resorption rates. The layers resorb sequentially over time through sequential exposure to body fluids. A resorption-controllable medical implant includes a series of two or more layers. The first layer includes a first bioresorbable material. The second layer includes a second bioresorbable material and resorbable particles of a first kind dispersed within the second bioresorbable material. Additional layers of bioresorbable material alone or including resorbable particles may be added to slow or speed resorption and achieve desired control over the resorption of the implant. Resorbable particles can be added in differing amounts or kinds in various segments of the implant to provide topographically differing resorption rates.
