A guide wire including a lubricous distal portion and a less lubricous intermediate portion proximal of said distal portion. One guide wire provides a highly lubricous distal portion with a hydrophilic layer and a less lubricous intermediate portion with a hydrophobic layer. Another guide wire provides a lubricous distal portion with a polymer tip that is itself hydrophilic. Yet another guide wire provides a less lubricous intermediate portion using a stainless steel coil helically wound around the tapering intermediate portion. The coil is preferably coated with a hydrophobic coating such as PTFE or silicone. The coil can either abut the distal portion proximal end or extend into the distal portion interior.

Novel methods and compositions are disclosed for bonding a hydrating cement-based overlay onto a cement-based substrate. An integral bond is created between the overlay and the substrate by maximizing capillary suction through properly preparing the substrate and designing the overlay. The integral bond has an interface strength at least substantially similar to the substrate strength. The substrate is prepared to optimize the capillary suction by cleaning and optimal water saturation. Properly designing the overlay for optimal capillary suction involves optimizing the water/cement ratio of each layer of the overlay. A low water/cement ratio is generally optimal. In addition to incorporating a low amount of water, the water to cement ratio is minimized through the use of dispersants and mixing techniques. The design of the overlay can also include silica fume to increase the strength of the interface bond.

A guidewire having an intermediate flexibility region to provide trackability and steerability while reducing guide catheter device back out. In one embodiment, the guidewire includes a distal flexibility region, intermediate flexibility region and proximal flexibility region. The intermediate or support flexibility region preferably extends from between about 3 cm to 40 cm proximally of the distal tip. The intermediate region is divided into at least two sections of varying stiffness.
