    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: 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 method is provided for increasing the outflow of fluid through Schlemm's canal that is useful for treatment of glaucoma. The implant is placed in Schlemm's canal by use of a flexible delivery instrument attached to the implant. The instrument and implant are positioned within the canal, the implant is released and the distal and proximal ends of the implant are connected to apply sufficient axial tensioning force on the inner wall of the canal to increase fluid permeability. In another embodiment a delivery instrument attached to the implant is positioned in the canal securing one of the distal or proximal ends of the implant within the canal. The implant provides sufficient axial tensioning force on the inner wall of the canal to increase fluid permeability of the inner wall of the canal. The other of the distal or proximal ends may be secured to maintain the tensioning force on the inner wall of the canal.
