Abstract: A superconducting magnet and method for making a superconducting magnet are presented. The superconducting magnet is made by forming a coil from windings of a first wire comprising a reacted MgB2 monofilament, filling a cavity of a stainless steel billet with a Mg+B powder. Monofilament ends of the first wire and a similar second wire are sheared at an acute angle and inserted into the billet. A copper plug configured to partially fill the billet cavity is inserted into the billet cavity. A portion of the billet adjacent to the plug and the wires is sealed with a ceramic paste.

Abstract: This disclosure relates to surgical instruments with selectively rotating handles. In certain aspects, the surgical device includes a conduit having a longitudinal axis and configured to extend into a body lumen, and a handle coupled to the conduit and configured to selectively rotate relative to the conduit. The handle is coupled to the conduit by a connection including a clutch mechanism, and the handle is configured to rotate in response to a user activation of the clutch mechanism.
