A vessel or biological duct repair device (100) and method includes a strap of material (102, 104) that is placed around the exterior surface of the vessel and drawn snugly about the vessel. The device can be used to seal an incision or rupture in a vessel, to correct an aneurysm, or to apply pressure to the exterior of the vessel. The device may also include a projection (130) or other means to aid grasping and positioning the device. The device may include a closure mechanism (110) that allows the device to assume various internal diameters or to exert varying amounts of pressure to a vessel. A layer of pro-coagulant material (120) may be provided on a vessel contacting surface of the device to promote clotting of any blood that escapes the vessel. The device may be prevented from moving relative to a surrounded vessel by ridges provided on the vessel contacting surfaces (106), by suturing the device to surrounding tissue, or by applying an adhesive to fix the device to the vessel.
