    Abstract: 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.

    Abstract: Controlled-release particles containing biologically effective agents such as therapeutic drugs and local anesthetics are suspended in a liquid suspending vehicle which has an elevated viscosity, the viscosity being substantially higher than that of water. Preferred vehicles are non-aqueous liquids and aqueous media which contain a dissolved polymer to increase the viscosity of the vehicle. Regardless of the composition of the media, however, the increased viscosity permits the use of particles of a relatively large size without a loss of suspension stability or localized application. The large particles offer the advantage of a longer release profile, and thus more prolonged activity of the agent.

    Abstract: A suture applying device includes a shaft which carries a pair of needles near its distal end. The needles are joined by a length of suture, and the shaft is used to both introduce the needles into a lumen of a body structure and to draw the needles back through tissue on either side of the puncture site. After the needles have passed through the tissue, they are captured by a needle receiver and drawn outward through the tract, leaving a loop of suture behind to close the puncture site near the body lumen. The suture can then be tied or otherwise secured to close the puncture site.
