Abstract
The emboli protection system provides one or more inflatable blocking balloons for isolation of a section of a blood vessel to prevent migration of emboli from the section during an interventional procedure, and fluid infusion and evacuation ports for flushing emboli from the isolated section. One embodiment provides for a distal blocking balloon catheter, over which an interventional device can be introduced, and a proximal blocking balloon catheter to be introduced over the interventional device for isolating a portion of a blood vessel to be treated. The blocking balloons can be perforated to provide the infusion ports, and thrombolytic inflation fluid may be used to break down and dissolve thrombus and plaque in the isolated portion of the blood vessel. The interventional therapeutic device such as an angioplasty balloon catheter may be incorporated into the distal blocking balloon catheter, or the distal and blocking proximal balloon catheters can be incorporated with the interventional therapeutic device together in one device. Infusion ports may also be provided in either or both of the distal and proximal blocking catheters.
