Abstract
In general, aspiration catheters have a suction device, a proximal portion and a shaft with a proximal end and a distal end. Improvements in the aspiration catheter design provide for improved tracking and/or reduced chance of snagging during delivery of the aspiration catheter. In some embodiments, the tip of the shaft has a curve relative to the neutral orientation of the remaining portions of the shaft. In other embodiments, the aspiration catheter further comprises a tracking portion that has a guide lumen. A guide structure can extend through the guide lumen to limit the motion of the tip of the catheter relative to the guide structure during delivery of the aspiration catheter within a patient's vessel. In further embodiments, the aspiration catheter comprises a deflection structure having a tether and a bumper. Improved methods for using the aspiration catheter to recover an embolism protection device are described.
