Abstract

A combined multi-lumen central access catheter and an embolic filter including ports proximal and distal the filter for fluid infusion and/or pressure sensing and infusion ports in the catheter to permit infusion of bioactive agents, flushing agents and/or contrast agents and managing the capture of the clot thereafter.

Claims

1. A medical device, comprising:

a. a multi-lumen catheter body having a first open port associated with a first fluid flow lumen and a second open port associated with a second fluid flow lumen;

b. a filter member having a first end immovably coupled to the multi-lumen catheter body and a second end movable relative to the multi-lumen catheter, the filter member being positioned substantially intermediate the first open port and the second open port such that the first open port is proximal the filter member and the second open port is distal the filter member, the filter member having a diametrically enlarged central opening which opens toward a patient'"'"'s blood flow. at least one infusion port associated with at least one infusion lumen in the multi-lumen catheter body and positioned within an area of the multi-lumen catheter body bounded by the filter member, wherein the at least one infusion port further comprises a plurality of infusion ports arrayed along a longitudinal axis and a circumferential axis of the multi-lumen catheter body; and

c. a clot management device operably coupled with the filter member.

2. The medical device according to claim 1, wherein the multi-lumen catheter body includes an annular lumen to dispose of clot lysing medications to be delivered to a clot captured in the filter member.

3. The medical device according to claim 1, wherein the clot management device comprises a thrombolytic scaffold operably coupled to the multi-lumen catheter body and the filter member, wherein the thrombolytic scaffold elute at least one thrombolytic drug.

4. The medical device according to claim 3, wherein the thrombolytic scaffold is positioned proximal to the filter member.

5. The medical device according to claim 4, further comprising a second thrombolytic scaffold positioned distally from the thrombolytic scaffold positioned proximal to the filter member.

6. The medical device according to claim 3, wherein the thrombolytic scaffold elutes at an increased rate when a blood clot is disposed within the filter member.

7. The medical device according to claim 1, wherein the filter member comprises a plurality of sharpened struts including an angled cross-section facing the central axis of the multi-lumen catheter body to shear a clot captured in the filter member during retrieval of the filter member to the retracted position.

8. The medical device according to claim 1, wherein the filter member comprises a plurality of sharpened struts including an angled cross-section facing adjacent struts to provide for a scissor-like action when the plurality of sharpened struts are moved towards the retracted position of the filter member.
