    摘要: A stent including hollow struts is formed on a cylindrical substrate. The struts of the stent are formed by electroforming metal layers of the strut in openings formed in a patterned photoresist material. A first metal layer forming the inner strut material is formed in openings in a first photoresist material. A sacrificial material to form the cavity to make the struts hollow is formed in openings in a second photoresist material. A second metal layer forming the side walls and outer wall of the struts is formed in openings in a third photoresist material and around the sacrificial material. The photoresist materials are removed. The substrate and cavity sacrificial material are removed, leaving hollow struts formed into a stent pattern. The hollow struts may be filled with a therapeutic substance for elution. Openings through the struts to the cavity may be formed during the forming process.

    摘要: Described herein are hydrogen sulfide (H2S) generating polymers and polymer systems suitable for coating or forming medical devices and methods for making and using the same. More specifically, described are H2S generating polymers comprising at least one thioamide group. The H2S generating polymers can provide controlled site-specific release of H2S once implanted at or within the target surgical site by hydrolysis of the thioamide group in physiological media. The H2S generating polymers can be coated onto a medical device, formed into a medical device or combined with one or more other polymers to form a polymer system. Also described are methods of treating restenosis and inflammation and promoting vasodilation utilizing such medical devices.

    摘要: A method of a forming a hollow, drug-eluting medical device includes providing composite member having an outer member and a core member disposed within a lumen of the outer member. The composite member is shaped into a pattern. Openings are formed through the outer member of the composite member. The composite member is processed to remove the core member from the lumen of the outer member without harming the outer member, leaving a hollow tubular member already formed into the desired pattern. The lumen of the outer member is filled with a therapeutic substance.
