1. A multi-lumen catheter comprising:
- a single catheter body member of a unitary material having a first lumen in the single catheter body member, the first lumen having a first transverse lumen cross-section, a second lumen in the single catheter body member, the second lumen having a second transverse lumen cross-section that is different from the first transverse lumen cross-section, and a third lumen in the single catheter body member, the third lumen having a third transverse lumen cross-section that is different from the first transverse lumen cross-section and the second transverse lumen cross-section;
wherein each of the first lumen, the second lumen and the third lumen reside within the single catheter body member, are laterally adjacent and parallel to each other and each have a proximal opening and a distal opening;
at least one elongate reinforcing member fixed within the unitary material of the single catheter body member or not in any of the first lumen, second lumen or third lumen; and
a sheath disposed about the body member, wherein the sheath forms a non-annular fluid passageway around an outside surface of the body member.

Abstract
A central access vena cava filter catheter having a multi-lumen catheter body with plural longitudinally extending parallel lumens within the single catheter body, a vena cava filter member disposed at a distal end of the catheter body and an outer sheath concentrically disposed about the multi-lumen catheter body and the vena cava filter member. The vena cava filter member may be removably coupled to the multi-lumen catheter for temporary placement and retrieval under recommended indications.

17. A multi-lumen catheter comprising:
-
a single catheter body member of a unitary material having a first lumen in the single catheter body member, the first lumen having a first transverse lumen cross-section, a second lumen in the single catheter body member, the second lumen having a second transverse lumen cross-section that is different from the first transverse lumen cross-section, and a third lumen in the single catheter body member, the third lumen having a third transverse lumen cross-section that is different from the first transverse lumen cross-section and the second transverse lumen cross-section; wherein each of the first lumen, the second lumen and the third lumen reside within the single catheter body member, are laterally adjacent and parallel to each other and each have a proximal opening and a distal opening; at least one elongate reinforcing member fixed within the unitary material of the single catheter body member or not in any of the first lumen, second lumen or third lumen; and
wherein the body member has a generally transverse cross-sectional shape having two generally planar lateral side walls, a first curvilinear surface connecting one end of the two generally planar lateral side walls and a second curvilinear surface connecting a second end of the two generally planar lateral side walls. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24)
