    摘要: 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.

    摘要: 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.
