Beschreibung
Zusammenfassung:	A catheter system includes an inflatable structural balloon and collapsible filter. The collapsible filter is deployable into an expanded configuration using the inflatable distal balloon. In the expanded configuration, one or more flow cells are formed between inflated portions of the balloon to provide continuous fluid flow between proximal and distal ends of the structural balloon. In the expanded configuration, the filter is configured to prevent particulates (e.g., dislodged thrombus, or other particulate material) from migrating beyond the filter. In the expanded configuration, the inflated structural balloon biases a perimeter of the filter toward or against a subject vessel wall.
