    摘要: The drug eluting folded stent and a stent delivery system, which includes a stent having a plurality of struts interconnected to form a tubular body. At least one of the struts includes a U-shaped strut having in cross-section a first leg, a second leg, and a closed end connecting the first leg and the second leg, wherein the first leg, the second leg, and the closed end define a recess having a drug release opening opposite the closed end; and a drug coating disposed on the first leg, the second leg, and the closed end within the recess. The drug release opening is sized to release a drug from the drug coating at a predetermined drug elution rate.

    摘要: Disclosed are medical devices having textured surfaces and biocompatible coatings disposed thereon. The textured surfaces allow for durable coatings to be applied to the medical device without a previous pre-coating having been applied. The biocompatible coating can further comprise a bioactive agent.

    摘要: Cells in a matrix or in the matrix in a vessel are grown to form a multicellular aggregate. Pressure is exerted on the growing cells by the matrix or the matrix together with the vessel due to growing cellular mass displacing the matrix. A value representing pressure exerted on the cells is calculated and the pressure is modulated to control growth of the multicellular aggregate, or to produce a multicellular aggregate of a pre-selected size or a pre-selected size and shape. Matrices include agarose, alginate and collagen gels, and the pressure exerted on the cells can be non-isotropic. The cells may be tumor cells, or liver, pancreatic, brain, skin, bone or muscle cells, and cell growth can be in vitro or in vivo. When collagen forms the matrix, the matrix may contain glycosaminoglycan.
