Abstract
A micromachined stent includes an elongate resilient wire formed into a coil for threading lengthwise into and through a catheter for ultimate discharge from the end of the catheter, to a target location in a blood vessel or body duct. When discharged, the wire resumes a coil form to hold the vessel or duct walls apart. Selective preferential flexibility is provided in the wire by placement of generally transversely formed cuts on the exterior of the wire.
