    摘要： The present invention relates to a method of polishing an implantable medical device. The method may include positioning an implantable medical device on a support. At least a portion of a surface of the implantable medical device may include a polymer. A fluid may be contacted with at least a portion of the surface of the positioned implantable medical device. In an embodiment, the fluid may be capable of dissolving at least a portion of the polymer at or near the surface of the implantable medical device. The method may further include allowing the fluid to modify at least a portion of the surface of the positioned medical device. A majority of the contacted fluid may be removed from the surface of the implantable medical device. In certain embodiments, the modified portion of the surface may be substantially less thrombogenetic and substantially more mechanically stable than an unmodified surface.

    摘要： Implantable medical devices fabricated from polymer/bioceramic composites with different types of bioceramic particles are disclosed. The plurality of bioceramic particles can include acidic particles and basic particles, the acidic particles and basic particles having different particle size distributions. The degradation of a selected type of particle can be reduced or prevented during a selected time frame by encapsulating some or all of the selected type of particles with a bioabsorbable polymer.

    摘要： An implantable medical device is disclosed having a helical construct including a set of spiral coils for local in vivo application of a therapeutic substance in a biological lumen. The helical construct is configured to apply less than 0.75 Bar of pressure to the biological lumen wall. The helical construct can have at least two sets of spiral coils having opposing helical directions. The device can be used for the treatment of vascular disorders such as restenosis and vulnerable plaque.
