Claims20
A device for removing an undesirable material comprising:
- a cannula comprising a polymer wall, a stepped cannula distal end, and an expandable funnel defined by a reinforcement element, a collar, and the polymer wall;
- wherein the collar is coupled to the stepped cannula distal.
A device for removing a pulmonary embolism comprising:
- an aspiration catheter comprising a polymer wall, a stepped distal end, and a self-expanding funnel;
- wherein the self-expanding funnel comprises a collar and a self-expanding reinforcement member both coupled to the polymer wall;
- and
- wherein the collar is coupled to the stepped distal end.
1 more element
A device comprising:
- an aspiration catheter comprising a polymer wall and a stepped distal end;
- a reinforced funnel defined by a collar, a reinforcement structure, and a radiopaque marker all embedded within the polymer wall;
- the reinforced funnel is configured to be coupled to the stepped distal end;
- and
- a macerator configured to be positioned within a lumen of the aspiration catheter.
