ABSTRACT:
A catheter irrigation device, readily attached to a fluid supply line connected to an indwelling catheter, is used to dislodge clots or blockages at the distal end of the catheter. The irrigation device comprises a pair of opposing rollers configured and positioned such that the fluid supply can be interposed between the rollers. The irrigation device further includes a flexible linkage which supports the rollers and maintains the rollers about the fluid supply tube. The flexible linkage is configured to receive the fluid supply tube and configured to deflect to cause the rollers to pinch the fluid supply tube, thus creating an occlusion. The flexible linkage and roller are further configured to slide over the fluid supply tube, such that with the rollers creating an occlusion in the tube, the irrigation device is slid for a sufficient distance toward the catheter to sufficiently increase the fluidic pressure within the catheter to dislodge the blockage. Alternatively, the device can be slid proximally for a sufficient distance to sufficiently decrease the fluidic pressure within the catheter to dislodge the blockage.
