Abstract
A dual braided catheter shaft includes an inner helical braid and outer helical braid than encapsulate an axially extending steering wire there between. In one embodiment, the shaft includes an inner polymer jacket, an inner braid formed on the inner jacket, a steering wire disposed along an outside surface of the inner braid, an outer braid formed over the inner braid and steering wire assembly and an outer jacket formed on the outer braid. The braiding parameters of the inner and outer braids can be varied along the length of the catheter to provide varying mechanical properties.
