Claims (21)

  1. 55 285734/ 0282082552- What is claimed is: 1. A device comprising: a catheter comprising a proximal portion and a distal portion; an impeller housing attached to the distal portion of the catheter with an impeller disposed therein, wherein the impeller housing comprises a distal portion and a proximal portion; and an expandable member aligned over an outside of the impeller housing, wherein an exterior surface of the expandable member is physically coupled directly to the exterior surface of the impeller housing, and wherein the expandable member expands and directs fluid flow to an inlet of the impeller housing.
  2. 2. The device of claim 1, wherein the exterior surface of the expandable member is physically coupled directly to the exterior surface of the impeller housing without any membrane, sheath, or device between the exterior surface of the expandable member and the exterior surface of the impeller housing.
  3. 3. The device of claim 1, wherein the expandable member surrounds, and is attached to, a proximal end of the impeller housing.
  4. 4. The device of claim 1 ,wherein the expandable member is a balloon.
  5. 5. The device of claim 4, wherein the balloon is inflatable and further wherein the balloon surrounds, and is attached to, a proximal end of the impeller housing.
  6. 6. The device of claim 1, wherein the impeller housing comprises a metal and a portion of the expandable member is physically coupled to a surface of the metal by an adhesive.
  7. 7. The device of claim 6, wherein at least a portion of the surface of the metal is impregnated with a polymer to promote bonding to the adhesive.
  8. 8. The device of claim 1, further comprising: a motor housing connected to the proximal portion of the catheter; a motor disposed within the motor housing; 56 285734/ 0282082552- a drive cable extending through the catheter from the motor to the impeller; and an inflation lumen extending along the catheter to the expandable member.
  9. 9. The device of claim 1 for use in a method for treating edema, the method comprising inserting the distal portion of the catheter into an innominate vein of a patient, operating the impeller, and expanding the expandable member to thereby decrease pressure at a lymphatic duct.
  10. 10. A device comprising: a catheter with a proximal portion and a distal portion, the distal portion dimensioned for insertion into a lumen of a patient and comprising a housing having a pump disposed within the housing; and an expandable member physically coupled directly to an exterior surface of the pump housing, wherein when expanded, the expandable member comprises a toroidal shape, wherein a proximal surface of the toroidal shape and an inner surface of the housing form a smooth continuous surface that funnels fluid, under power of the pump, through the housing.
  11. 11. The device of claim 10, wherein an inner radius of the toroidal shape is substantially the same as a radius of the proximal end of the impeller housing.
  12. 12. The device of claim 10, wherein the expandable member comprises an inflatable balloon mounted on the pump.
  13. 13. The device of claim 12, wherein the pump comprises an impeller disposed within the housing, with the balloon connected to an exterior surface of a proximal end of the housing.
  14. 14. The device of claim 13, wherein the housing comprises a distal portion and a proximal portion, wherein an external diameter of proximal portion is smaller than an external diameter of the distal portion, wherein the expandable member, when not expanded, is disposed around the proximal portion of the impeller housing.
  15. 15. The device of claim 14, wherein the impeller comprises one or more blades on a shaft, wherein a radial measurement taken from an axis of the impeller to an outer edge of the blades decreases from a distal to a proximal portion of the impeller. 57 285734/ 0282082552-
  16. 16. The device of claim 15, wherein the outer edge of each blade includes a dogleg defining a step-down in radius located adjacent a transition between the distal portion and the proximal portion of the impeller housing.
  17. 17. The device of claim 14, wherein the distal portion of the housing comprises one or more outlets and, wherein the impeller shaft flares outwards near a distal end of the impeller such that when the impeller is rotated, the impeller pumps blood through the impeller housing and out of the one or more outlets.
  18. 18. The device of claim 10, wherein the pump comprises an impeller disposed within an impeller housing and the expandable member comprises an inflatable balloon connected to an exterior surface of the impeller housing.
  19. 19. The device of claim 18, wherein when the balloon is inflated, it defines a torus.
  20. 20. The device of claim 1, wherein the exterior surface of the impeller housing is prepared such that the exterior surface of the impeller housing includes at least one of a primed surface, a chemically activated surface, a plasma activated surface, a mechanically abraded surface, a laser ablated surface, an etched surface, or a rough surface, a patterned surface, or a high energy surface.
  21. 21. The device of claim 1, wherein the expandable member is physically coupled directly to the exterior surface of the impeller housing via an interfacial layer, the interfacial layer configured to interpenetrate the prepared exterior surface of the impeller housing.
