Abstract
Multilumen catheters are provided. The subject multilumen catheters include a proximal end and a distal end separated by a non-coaxial multilumen tube. The subject catheters are further characterized in that they include a multiport manifold at their proximal ends, where at least two of the ports of the multiport manifold may comprise luer valves. Also provided are systems for use in flushing a vascular site with fluid, usually at least two different fluids, where the subject systems are made up of two multilumen catheters according to the subject invention, where one of the catheters is inserted inside of the other. In addition, kits comprising various components of the subject systems, e.g., at least two different multilumen catheters, are provided. The subject multilumen catheters, systems and kits find use in a variety of different applications in which it is desired to flush a vascular site with at least one and preferably two different fluids, where particular applications of interest include the treatment of vascular lesions.
