    摘要： A device and method for delivering a drug from inside a body lumen to tissue surrounding the body lumen. An endoluminal drug delivery device includes a dual-lumen catheter for housing a guidewire and a needle connectable to a drug source. The guidewire exits the catheter through an opening at the distal end, and the needle exits the catheter through an exit port in the outer wall of the catheter. A distal portion of the catheter has a single lumen and includes a taper, allowing the distal tip to act as a dilator. The device optionally includes a catheter lumen splitter and/or a handpiece assembly. A method of delivering fluid to tissue surrounding a body lumen includes inserting a guidewire into the body lumen, tracking the device over the guidewire, deploying the needle through the exit port to the tissue, delivering fluid, and retracting the needle into the catheter.

    摘要： Kits, apparatus, devices and methods for treating varicose veins caused by an incompetent venous junction (e.g., the saphenofemoral and/or saphenopopliteal junctions) are disclosed. The kits may include a sheath, a vein closure device, and an injection device. Alternatively, a vein closure device may include an integral injection channel and injection device. Methods may include injecting a vein with a sclerosing agent through a needle that extends in a direction that is not aligned with a longitudinal axis of a sheath or shaft.

    摘要： A catheter assembly comprises a catheter including a catheter wall and a lumen extending lengthwise of the wall. The wall has inner and outer surfaces. The wall includes plural openings that extend through the wall and communicate with the lumen. An elongated hollow needle includes a proximal end portion and a distal end portion. The needle is movable in the lumen to move the distal end portion between the openings. The distal end portion is directed radially outward so as to extend into an adjacent opening. The distal end portion has a configuration that stores potential energy when in the lumen. The potential energy is converted to kinetic energy to produce movement of the proximal end portion as the distal end portion moves from the inner surface of the catheter wall across an edge of an opening. The movement of the proximal end portion is haptically perceptible.

    摘要： A catheter system comprising a) an elongate flexible catheter; b) a lumen that extends from a proximal insertion port to a side outlet opening; c) a penetrating guidewire insertable into the proximal insertion port and thereafter advanceable through the lumen and out of the side outlet opening; and d) an orientation element useable to provide an indication of the trajectory on which the penetrating guidewire will advance from the catheter body. Also disclosed are methods for using such catheter to direct the penetrating guidewire out of the side opening and into the true lumen of a blood vessel when bypassing an obstruction in the blood vessel such as a chronic total occlusion (CTO) of an artery.
