    摘要: A vascular structure (24), including an artery, vein or vessel, with a peripheral wall (40) defining a cavity (32) and having a localized abnormal wall (20) is treated by inserting a device (44) of a hydrogel material into the cavity (32); and then hydrating and expanding the hydrogel material until the device (44) occludes the localized abnormal wall (20), sealing it from the cavity (32) of the vascular structure (24). For delivery and placement of the hydrogel implant (44) a catheter (80) is provided comprising an expandable balloon (84) affixed to the distal end of the catheter (80).
