Reduced profile central venous access catheter with vena cava filter and method
First Claim
1. A multi-lumen catheter comprising a single catheter body member, wherein the body member has a generally transverse cross-sectional shape having 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;
- the single catheter body member having formed therein a first lumen having a first transverse lumen profile and a second lumen having a second transverse lumen profile different from the first transverse lumen profile;
wherein each of the first lumen and the second lumen spaced apart and parallel relative to each other within the single catheter body member and each have a proximal opening and a distal opening such that fluid flow may pass therethrough; and
a sheath disposed about at least a longitudinal portion of the single catheter body member, in spaced apart relationship with the single catheter body member forming a fluid passageway between an inner surface of the sheath and an outer surface of the single catheter 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.
