Patent abstract

An obstruction removal system for percutaneous removal of clots or obstructions within the vascular system is disclosed. The obstruction removal system includes a multi-lumen catheter with a plurality of circulating capture devices attached to or integral with a drive belt. The circulating capture or interference devices affect removal of the clot or obstruction bit-by-bit through a series of passes. The obstruction removal system may include one or more drive mechanisms, such as a pulley system and/or a vacuum source and/or a pressurization source, on its proximal end for driving the drive belt and capture devices through the catheter in a circulating manner. The obstruction removal system may also include one or more cleaning mechanisms, such as a vacuum chamber and/or a fluid rinse chamber, for removing the captured clot pieces from the capture devices.
