摘要：
A suction catheter system is described with a suction nozzle that can extend from a guide catheter of the like. The suction nozzle can be positioned by tracking the suction nozzle through a vessel while moving a proximal portion of the suction extension within the lumen of the guide catheter. A suction lumen extends from the proximal end of the guide catheter through at least part of the guide catheter central lumen and through the suction tip. Desirable suction flow can be established using the guide lumen to facilitate the suction. Also, a delivery catheter is described with an elastic tip that can track closely over a guidewire. The elastic tip of the delivery catheter can be expanded to provide for the delivery of medical devices past the tip.
