    摘要: A device for engaging tissue may include a generally annular-shaped body defining a plane and disposed about a central axis extending substantially normal to the plane. The body may be movable from a substantially planar configuration lying generally in the plane towards a transverse configuration extending out of the plane. The body may include a plurality of looped elements including alternating inner and outer curved regions. The inner curved regions may define an inner periphery of the body and the outer curved regions may define an outer periphery of the body in the planar configuration. A plurality of tines may extend from the outer curved regions. The tines may be oriented generally towards the central axis in the planar configuration and generally parallel to the central axis in the transverse configuration. The tines may extend beyond the central axis without passing through the central axis so as to collectively form a central lumen about the central axis in the planar configuration.

    摘要: Various embodiments of the present invention provide a medical device comprising at least one blood-contacting surface comprising a porous hydrophobic polymer substrate, wherein at least a portion of the at least one blood-contacting surface comprises a hemocompatible polymer substrate. One embodiment of the present invention relates to the providing of expanded poly(tetrafluoroethylene) with one or more complexes of heparin, typically containing heparin in combination with a hydrophobic counter ion. The hemocompatible substance is dissolved in a mixture of solvents in which a first solvent wets the polymer substrate to be coated and the second solvent enhances the solubility of the hemocompatible substance material in the solvent mixture. Typical first solvents wetting a hydrophobic polymer substrate include non-polar such as hydrocholorofluorocarbons. Typical second solvents include polar solvents such as organic alcohols and ketones. Azeotropic mixtures of the second solvent in the first solvent are used in some embodiments of the present invention although second solvents may be employed in a range of concentration ranges from less than 0.1% up to saturation.

    摘要: The invention relates to a directional drug delivery stent which includes an elongated or tubular member having a cavity containing a biologically active agent. In one embodiment, the active agent is diffused from the reservoir directly to the walls of a body lumen, such as a blood vessel, through directional delivery openings arranged on an outer surface of the elongated member. Another variation of the stent includes an osmotic engine assembly for controlling the delivery of the active agent from the reservoir. The drugs which may be applied by the directional delivery stent include, but are not limited to, steroids, anti-inflammatory agents, restenosis preventing drugs, anti-thrombotic drugs, and tissue growth regulating drugs. The invention also relates to a method of using the directional drug delivery stent.
