Infusion treatment agents, catheters, filter devices, and occlusion devices, and use thereof

A method comprising:

• winding a plurality of layers of ePTFE onto a large mandrel;
• bonding a seam between two of a plurality of second ePTFE windings;
• fusing together the layers of ePTFE;
• heating the layers of ePTFE at a temperature of approximately 380 degrees celsius for a duration of between 20 minutes and 30 minutes;
• stretching the fused layers of ePTFE onto a small mandrel, wherein stretching comprises:
• putting the small mandrel within an inner diameter of fused ePTFE layers;
• stretching apart a distal end and a proximate end of the ePTFE sufficiently to stretch the inner diameter of fused ePTFE layers onto an outer diameter of the small mandrel;
• compacting the stretched fused layers of ePTFE axially;
• one of wrapping an outer diameter of the stretched fused layers of ePTFE with a polytetrafluoroethylene, and constraining the outer diameter of the stretched fused layers of ePTFE within a steel tube before compacting, and then sufficiently compacting axially inwards a distal end and a proximate end of the stretched fused layers of ePTFE, such that during inflation of the lined ePTFE balloon, the compacted stretched fused layers of ePTFE may not expand axially
• bonding a balloon liner to the compacted stretched fused layers of ePTFE to form a lined ePTFE balloon.
