Abstract

Medical devices that include micromachined hypotubes or that have themselves been micromachined can provide advantages in flexibility, strength and other desirable properties. Examples of such medical devices may include catheters such as guide catheters and balloon catheters. Such devices may also include dual shaft medical devices in which an outer shaft is reversibly lockable onto an inner shaft.
