Patent attributes
A directional balloon is provided that can be used for a medical intervention of a body lumen. In one aspect, the directional balloon inflates in a distal to proximal direction and deflates in a proximal to distal direction. In another aspect, the directional balloon inflates in a proximal to distal direction and deflates in a distal to proximal direction. The directional balloon is capable of providing an occlusive seal to protect against embolization. A suction catheter with a control means is provided to provide suction in a controlled fashion in a body lumen. The suction catheter is used during periods of a medical intervention that risks distal embolization. When turned on, the suction catheter is capable of removing unwanted materials. The suction means could be operated by a control means.
