1. A method of capturing undesired material from a vessel, the method comprising:
positioning a cannula at a treatment site comprising the undesired material within the vessel, the cannula is configured to be operatively coupled to a suction source, wherein the cannula includes an expandable atraumatic tip at a distal end thereof, the expandable atraumatic tip configured to transition between a non-deployed position and a deployed position;
transitioning the expandable atraumatic tip to the deployed position; and
activating the suction source in a cyclic manner configured to generate a suction force through the cannula, wherein the combination of the suction force through the deployed expandable atraumatic tip is configured to remove the undesirable material;
engaging the undesired material via the expandable atraumatic tip;
pausing the activation of the suction source;
transitioning the expandable atraumatic tip from the deployed position to the non-deployed position;
repositioning the cannula within the vessel;
transitioning the expandable atraumatic tip from the non-deployed position to the deployed position; and
reactivating the suction source.
