Devices for clearing blockages in in-situ artificial lumens
A device for the breaking-apart of occlusions includes a stationary fitting, a hollow tube and a second fitting configured to reciprocate so as to cause the hollow tube to be compressed and expanded. The hollow tube is coupled on one side to the stationary fitting, and the stationary fitting provides access to a hollow portion of the hollow tube.
