1. A catheter having a distal region and a proximal region, the catheter comprising:
- an elongate tube having a distal end and a proximal end defining a length therebetween, the elongate tube extending from the proximal region to a distal end of the distal region, the elongate tube comprising a plurality of slots disposed substantially along the entire length of the elongate tube, the slots extending radially about the elongate tube, each slot extending only partially around the circumference of the elongate tube, at least two of the slots being disposed at the same axial position along the elongate tube; and
a polymeric dual-lumen liner disposed within the elongate tube.

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.
