摘要:
This invention provides implantable medical devices that include delivery systems containing amino acid derivatives, and related methods for making and using. More specifically, this invention provides vascular stents with coatings containing methyl ester derivatives of amino acids, and related methods for making and using.
摘要:
The drug eluting rolled stent and a stent delivery system, which includes a catheter; a balloon operably attached to the catheter; and a stent disposed on the balloon. The stent includes a rectangular metal foil sheet having a first side and a second side, the rectangular metal foil sheet being rolled to form a cylindrical tube having a central axis and a spiral cross section perpendicular to the central axis; a polymer drug coating disposed between and adhering the first side and the second side; and at least one opening formed through the cylindrical tube generally perpendicular to the central axis, the at least one opening being shaped to form at least one strut having in cross section polymer drug layers between metal foil layers, polymer drug layer edges of the polymer drug layers being in communication with the at least one opening.
摘要:
A method of treating a condition involving vascular adhesion of cytotoxic white cells by (a) identifying an animal suspected of having a condition involving vascular adhesion of cytotoxic white cells and (b) administering to the animal an amount of bFGF sufficient to decrease cell surface expression of ICAM-I or VCAM-I on endothelial cells, thereby reducing adhesion of cytotoxic white cells to vascular endothelium.
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:
The present invention relates to a novel human protein called Fibroblast Growth Factor 15, and isolated polynucleotides encoding this protein. Also provided are vectors, host cells, antibodies, and recombinant methods for producing this human protein.
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.
