Abstract: A surgical appliance for assisting in the repair of a fractured bone, such as a scaphoid bone, is disclosed. The device includes first and second adjustably interconnected and spaced apart limb clamping jaws that are transparent to x-ray radiation and are relatively movable toward and away from one another and a rotatable disk carried by the first jaw, said disk having a plurality of bores angularly disposed in the disk for selectively aligning a guide wire to be drilled percutaneously into the fractured bone. Each of the bores are in communication with the space between the first and second jaws and the longitudinal axes of said bores are directed to a common point intermediate the first and second jaws.

Abstract: A surgical procedure for revascularization the myocardium, comprising the steps of: directing a generally cylindrically shaped first nozzle into a heart wall being treated; forming a first or main channel in the heart wall from the ventricle into the myocardium of the heart by the nozzle; removing a generally cylindrically shaped tissue core through the nozzle, from the heart wall during formation of the first or main channel. A set of tributary channels may be made in the heart wall from and in communication with the main channel by an arrangement of radially directed fluid jets subsequent to the creation of that main channel.
