Patent ID: 8167902

Claim:
A catheter having a proximal portion and a distal portion, the catheter comprising: a first elongate tubular body having a proximal portion, a distal portion, a proximal end, a distal end, and a lumen extending between the proximal end and the distal end; a second elongate tubular body having a proximal portion, a distal portion, a proximal end, a distal end, and a lumen extending between the proximal end and the distal end; and an elongate member having a proximal portion, a distal portion, a proximal end, and a distal end, the elongate member joining the first and second elongate tubular bodies, the first elongate tubular body being disposed distal and tandem to the second elongate tubular body, and the first tubular body being fixedly attached on the distal portion of the elongate member, the second elongate tubular body being disposed on the elongate member and the second elongate tubular body being slidable along a portion of the elongate member, wherein the second elongate tubular body is able to be disposed in a first position so that the first and second tubular bodies are not adjacent to each other and able to be disposed in a second position so that the first and second tubular bodies are adjacent to each other, wherein the catheter comprises a locking mechanism that is adjustable between an open configuration and a locked configuration, and when the locking mechanism is in an open configuration the first and second elongate tubular bodies are not locked together and when the locking mechanism is in a locked configuration the first and second elongate tubular bodies are adjacent to each other and locked together and the lumens of the first and second elongate tubular bodies form one continuous lumen, and wherein no portion of the elongate member is in the lumen of the first elongate tubular body.
