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.

Claims

1. A system for flushing a vascular site, said system comprising:

(I) a first two lumen catheter comprising;

(A) a proximal end;

(B) a distal end; and

(C) a three port manifold located at said proximal end, wherein;

(i) said three port manifold comprises at least two offset ports having luer valves and a central port comprising a Touhy-Borst valve; and

(ii) said proximal and distal ends are separated by a non-coaxial two lumen tube; and

(II) a second multilumen catheter inserted inside of one of said two lumens of said first two lumen catheter;

wherein said second multilumen catheter is a three lumen catheter comprising;

(i) a proximal end;

(ii) a distal end; and

(iii) a three port manifold located at said proximal end, wherein, each port of said three port manifold comprises a luer valve; and

said proximal and distal ends are separated by a non-coaxial three lumen tube.

3. A method for flushing a vascular site with fluid, said method comprising:

(a) introducing a system according to claim 1 into a patient in a manner such that the distal ends of said multilumen catheters of said system are located at said vascular site; and

(b) flushing said vascular site with at least one fluid by introducing fluid into and removing fluid from said vascular site through the lumens of said system.

2. A kit for using in flushing a vascular site with fluid, said kit comprising:

(I) a first two lumen catheter comprising;

(A) a proximal end;

(B) a distal end; and

(C) a three port manifold located at said proximal end, wherein;

(i) said three port manifold comprises at least two offset ports having luer valves and a central port comprising a Touhy-Borst valve; and

(ii) said proximal and distal ends are separated by a non-coaxial two lumen tube; and

(II) at least one second multilumen catheter comprising a three lumen catheter comprising;

(i) a proximal end;

(ii) a distal end; and

(iii) a three port manifold located at said proximal end, wherein;

(a) each port of said three port manifold comprises a luer valve; and

(b) said proximal and distal ends are separated by a non-coaxial three lumen tube.
