1. A system for removing an undesirable material, the system comprising:
a cannula comprising a polymer wall, a stepped cannula distal end, and an expandable element coupled to the stepped cannula distal end by a collar, the expandable element and the collar being embedded within the polymer wall;
a pump operatively coupled to the cannula and configured to generate a suction force through the cannula; and
a reservoir operatively coupled to the pump and in fluid communication with the cannula, wherein the pump is configured to generate a driving force into the reservoir,
wherein the pump is configured to generate the suction force independently of or alternatively with the driving force.
