Abstract
A method and apparatus to terminate sacral hemorrhaging in a patient having a sacrum and a pubic bone is disclosed. A C-shaped driver is positioned around the pubic bone of the patient and a hemorrhage occluder pin is driven into the sacrum of the patient by applying an impact force to a proximal end of the C-shaped driver. The driver may include a C-shaped shaft that defines a radius in the range 50 mm to 200 mm and a maximum span in the range 100 mm to 650 mm. The proximal end of the C-shaped shaft may have a blunt face with a breadth that is at least 2.5 times the diameter of the pin cap. A shaft distal end has a driver face facing away from an interior of the C-shape, and defining a driver face diameter that is preferably no less than 50% of the pin cap diameter.
