    摘要： An ablation catheter system for capturing and removing necrotic tissue and thrombi generated during an ablative procedure is disclosed. The catheter typically includes an elongate member, a filtration assembly disposed within the distal region, and an ablation instrument at the distal end. Alternatively, the ablation instrument is carried on the distal end of an ablation catheter, which is disposed within a lumen of the catheter system. The catheter may further include an aspiration port and lumen. Methods of using the devices in preventing distal embolization during ablative procedures are disclosed.

    摘要： A method for carotid endarterectomy. A blood filter is positioned within a carotid artery downstream of an atheromatous plaque. The filter is expanded. The carotid artery is clamped upstream and downstream of the atheromatous plaque while the filter is expanded. An endarterectomy procedure is performed on the region of the carotid artery having the atheromatous plaque. The carotid artery is unclamped while the filter is expanded. In certain cases a shunt is positioned in a region of the carotid artery having the atheromatous plaque and secured to the shunt by clamping, the shunt comprising a tubular member having a proximal opening, a distal opening, and a lumen therebetween.

    摘要： A shunt and method of use for maintaining distal blood flow during an arteriotomy procedure is disclosed. The shunt includes a first tubular member having a proximal end, a distal end, and a lumen therebetween. The proximal end has an opening in communication with the lumen, and the proximal opening is adapted to receive blood from a first region of an artery. The distal end has an opening in communication with the lumen, and the distal opening is adapted to release blood into a second region of the artery. The shunt includes a second tubular member having a proximal end, a distal end, and a lumen therebetween which either merges and communicates at its distal end with the lumen of the first tubular member, or rides separate and parallel to it. The shunt also includes a hemostatic valve attached to the proximal end of the second tubular member, the valve acting to prevent loss of blood from the lumen of the second tubular member and to permit the introduction of a medical device into the lumen of the second tubular member and into the artery. In use, the distal opening of the shunt is inserted into the second region of an artery and secured to the lumen of the artery. A blood filter device is deployed within the artery. The proximal opening of the shunt is inserted into the first region of the artery and secured to the lumen of the artery. Endarterectomy is performed on the region of the artery which lies between the proximal opening and the distal opening of the shunt, and embolic material dislodged during the procedure is captured by the filter.

    摘要： Devices and methods for filtering blood. The devices generally comprise: a mesh for filtering blood flowing within a blood vessel, particularly within an artery such as the aorta; a structure adapted to open and close the mesh within the blood vessel; and a means to actuate the structure. The methods generally include the following steps: introducing a mesh into a blood vessel to entrap embolic material; adjusting the mesh, if necessary, during the course of filtration; and removing the mesh and the entrapped foreign matter from the blood vessel. Additionally, visualization techniques are used to ensure effective filtration.
