Abstract
A catheter system includes a multi-lumen working catheter having a first distal working orifice and a second distal working orifice. The catheter system further includes a guide catheter having a guide lumen and a distal guide orifice. Also, the catheter system includes a locking mechanism which locks the working catheter relative to the guide catheter in (i) an operative position, and (ii) a stowed position. When the working catheter is locked in the operative position, (i) the working catheter extends through the guide lumen of the guide catheter and out of the distal guide orifice of the guide catheter, and (ii) the first distal working orifice and the second distal working orifice are each positioned outside of the guide catheter. Additionally, when the working catheter is locked in the stowed position, (i) the working catheter extends into the guide lumen of the guide catheter, and (ii) the first distal working orifice and the second distal working orifice are each positioned within the guide lumen of the guide catheter. A method of performing dialysis with a catheter system is also disclosed.
