Abstract:
1. A filtration system comprising: a catheter comprising a tubular element having a proximal end and a distal end, an occlusive element mounted toward the distal end on the exterior of the tubular element, a lumen extending through the tubular element with a distal opening, a first filter element at a securely fixed position proximal to the distal opening, an open portion of the tubular element proximal to the occlusive element near the distal end in fluid communication with the first filter element, wherein the first filter element is configured to filter flow entering the lumen at the distal opening as unfiltered flow before the flow exits the catheter through the open portion of the tubular element; and a filter device comprising a guide structure and a second filter element distinct from the first filter element mounted on the guide structure, wherein the guide structure extends within the lumen of the catheter, which is configured for the delivery of the second filter element mounted on the guide structure.
