    摘要: A stent of variable surface area as determined by stent struts. The stent can have a variable surface area per unit length which accommodates a therapeutic agent. A patterned distribution of therapeutic agent can be provided throughout the stent. The stent can have an increased level of therapeutic agent near an end of the stent. A decreased level of therapeutic agent can be provided near an end of one embodiment of a stent. Indentations can be provided at the surface of the stent with therapeutic agent disposed therein. The stent can be cut with struts of variable thickness to provide the variable stent surface area.

    摘要: The present invention generally encompasses the control of the release rate of agents from a polymeric matrix. This control over the release rate of agents provides for control over, inter alia, the therapeutic, prophylactic, diagnostic, and ameliorative effects that are realized by a patient in need of such treatment. In addition, the control of the release rate of agents also has an effect upon the mechanical integrity of the polymeric matrix, as well as a relationship to a subject's absorption rate of the absorbable polymers.
