| 20100152709 | Dysfunction Resistant Catheter Systems and Associated Methods - A catheter assembly includes a first line having (i) a first proximal end portion defining a first opening, (ii) a first distal end portion defining a second opening, and (iii) a first fluid passage extending between the first opening and the second opening. The catheter assembly includes a second line having (i) a second proximal end portion defining a third opening, (ii) a second distal end portion defining a fourth opening, and (iii) a second fluid passage extending between the third opening and the fourth opening. The catheter assembly further includes an actuator movable between a first location and a second location. In addition, the catheter assembly includes a linkage connected between the actuator and the first distal end portion of the first line. The first distal end portion of the first line is movable in relation to the second line between (i) a first position in which the first distal end portion is positioned in abutment with the second line, and (ii) a second position in which the distal end portion is spaced apart from the second line. Movement of the actuator from the first location to the second location causes movement of the first distal end portion from the first position to the second position. | 06-17-2010 |
