Multi-lumen central access vena cava filter apparatus

A central venous access vena cava filter catheter (10), comprising: a. a multi-lumen catheter body (12) having a first port (32) associated with a first lumen (44) and a second port (34) associated with a second lumen (42); and b. a vena cava filter member (16) concentrically coupled to the multi-lumen catheter body (12) and positioned between the first port (32) and the second port (34) such that the first port (32) is proximal to the vena cava filter member (16) and the second port (34) is distal to the vena cava filter member (16), the vena cava filter member (16) comprises a plurality of structural members (62, 64, 66) and a rim member (70), wherein the plurality of structural members (62, 64, 66) comprises a first set of structural members (62) attached at a proximal end to a proximal portion of the vena cava filter member (16), a second set of structural members (64) attached at a distal end thereof to a distal portion of the vena cava filter member (16), wherein the proximal portion of the vena cava filter member (16) is concentrically attached to the multi-lumen catheter body (12) and the distal portion of the vena cava filter member (16) is movably and concentrically positioned around the distal portion (14) of the multi-lumen catheter body (12) and coupled thereto, and wherein the ring member (70) is coupling an end of the first set of structural members (62) to a proximal portion of the second set of structural members (64).
