    摘要: An assembly for insertion into the cardiovascular system of a patient comprising a catheter having first and second lumens and a distal port. The first lumen opens at the distal port. A probe is received in the second lumen. The probe includes a sensor responsive to a constituent of blood for providing a signal which is related to the constituent. The catheter has a window for allowing the constituent of blood to pass from outside the catheter to the sensor while substantially preventing other constituents of blood from passing from the outside of the catheter to the sensor.

    摘要: A dispenser in which a dry powder (one component of a two-part adhesive tissue sealant and/or adhesive) is stored in a container (e.g., a carpule) having a septum at one end, an open end opposite the septum, and a movable plug. The powder is retained at the septum end of the container by the movable plug, which is displaced and pushed back as the solvent used for reconstituting the powder is introduced (e.g., through the septum). The second part of the tissue sealant is contained within a second container, also with a movable plug. After the first part is reconstituted, a manifold is fitted which pierces both septums and allows the contents to be dispensed. A dual syringe body supports the containers, and has pistons that enter the open ends to advance the movable plugs. Other embodiments of tissue adhesive and/or sealant dispensers and kits as well as methods of preparing tissue sealants are also described.

    摘要: A catheter is provided with a heated temperature self regulating tip for insertion in an artery to ablate an atherosclerotic plaque obstruction particularly in coronary and peripheral arteries. The heater is located at the distal end of the catheter and has a winding of fine wire around a ferro-magnetic core with the wire being connected via a transmission line to a high frequency constant alternating current source in the megahertz range. The catheter which may or may not employ a guide wire is inserted into and through the lumen of a vessel and guided usually with the assistance of fluoroscopy to the location of the stenosis. The heater is energized to ablate the plaque, the temperature not exceeding a desired temperature as determined by the Curie temperature of the ferromagnetic material.
