ABSTRACT:
A thrombolysis catheter system having a fixed length infusion zone is disclosed. The invention contemplates apparatus, method and kit aspects. The apparatus, which has the capability to track a guidewire, uses a multilumen catheter to deliver radially thrombolytic agent to an infusion zone defined by one or more balloon means. In one aspect, with an occluder means, a primary lumen of the catheter is used both for catheter placement and delivery of fluid. The method discloses utilization of radiopaque indicia to place the catheter in proximity to the occlusion or diseased tissue to be treated. The kit includes a catheter of the invention in conjunction with a steerable guidewire and a tip occluder wire, either or both of the tip occluder wire and the guidewire having an enlargement on their distal tip which cooperates with a reduced diameter portion of the catheter lumen.
