Abstract:
Apparatus for insertion into a blood vessel for eliminating thrombus in the blood vessel, said apparatus comprising:a primary thrombolytic fluid delivery system comprising a first group of infusion ports for delivering a first amount of thrombolytic fluid which chemically reacts with an initially whole thrombus structure to cause the thrombus structure to chemically breakdown into several thrombus fragments smaller than the initially whole thrombus structure, and a secondary thrombolytic fluid delivery system, located axially spaced apart from the primary thrombolytic fluid delivery system, comprising a filter member for trapping the several thrombus fragments and a second group of infusion ports located in the filter member for delivering a second amount of thrombolytic fluid which chemically reacts with the several thrombus fragments to cause the several thrombus fragments to further chemically breakdown and completely dissolve in the filter member.
