A medical device for delivering a biologically active material into a body tissue, comprising struts and optionally the biologically active material. In an embodiment, the medical device comprises non-structural elements integral with the struts. A method for designing such medical device are also disclosed. Another embodiment is a medical device having an outer surface comprising a middle section and end sections. The end sections have a greater available surface area, greater affinity for or a greater amount of the biologically active material per unit length of the outer surface than the middle section. The middle section may be covered with a barrier layer. Another embodiment is a medical device comprising a rectangular portion having a greater capacity for carrying a biologically active material per unit length of the outer surface. A method for delivering a biologically active material to a body tissue is also disclosed.
A medical device for delivering a biologically active material to a body tissue of a patient in need of treatment, wherein the medical device comprises a plurality of struts and a plurality of non-structural elements integral with the struts, wherein the struts and the non-structural elements comprise the biologically active material.
A method for designing a medical device for delivering a biologically active material to a body tissue of a patient, wherein the medical device comprises a plurality of struts and a plurality of non-structural elements integral with the struts, wherein the struts and the non-structural elements comprise the biologically active material, wherein the method comprises:
A medical device insertable into the body of a patient, which comprises an outer surface comprising a plurality of struts, wherein the outer surface has a middle section and end sections, and wherein the end sections have a greater available surface area per unit length of the outer surface than the middle section.
A medical device insertable into the body of a patient, which comprises an outer surface comprising a plurality of struts, wherein the outer surface has a middle section and end sections, and wherein the end sections a greater affinity for the biologically active material area per unit length of the outer surface than the middle section.
A medical device insertable into the body of a patient, which comprises an outer surface, wherein the outer surface has a middle section and end sections, wherein at least a part of each of the middle section and the end sections is covered with a coating layer comprising a first biologically active material, and wherein the end sections carry or contain a larger amount of first biologically active material per unit length of the outer surface than the middle section.
A medical device insertable into the body of a patient, which comprises an outer surface, wherein the outer surface has a middle section and end sections, wherein at least a part of each of the middle section and the end sections is covered with a coating comprising a first biologically active material, and the middle section comprises a barrier layer placed over the coating covering the middle section for reducing the release rate of the biologically active material.
A medical device insertable into the body of a patient, which comprises an outer surface comprising a plurality of struts, wherein the outer surface has a rectangular portion having a greater capacity for carrying or containing a biologically active material per unit length of the outer surface than the parts of the outer surface that are outside the rectangular portion, by having a greater surface for carrying or having a greater affinity for the biologically active material than the parts of the outer surface that are outside the rectangular portion.
