  • Perfusion-occlusion apparatus
    Patent number: 6165196
    Abstract: A perfusion-occlusion catheter provides an occluded region in a vessel to facilitate, for example, an anastomosis in the region, while providing a path for perfusing fluid (blood) through the path for delivery in the vessel downstream from the occluded region. According to one aspect of the invention, at least a portion of the catheter that effects vessel occlusion comprises a shield that when exposed to suture needles or like piercing instruments deflects or resists perforation.
