Claim Text:
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 body, 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; c. a clot management device operably coupled with the filter member, comprising a clot detection wire disposed within at least one lumen of the multi-lumen catheter body, wherein the clot detection wire includes a distal looped configuration when disposed within the filter member in an expanded state; and d. the clot detection wire includes a plurality of depth markers at defined distances along a distal end of the clot detection wire, wherein if the distal looped configuration is not expanded within the expanded state of the filter member, then the plurality of depth markers are collapsed to indicate a clot within the filter member.
