摘要：
In some aspects, catheter devices can include: a reinforcing member having a proximal and distal ends, the reinforcing member comprising: discrete longitudinally arranged structural regions between the proximal and distal ends comprising: a first, proximal, structural region defining a first series of wall perforations that generate structural properties within the first structural region, the first series of wall perforations setting a first stiffness of the first structural region； and a second structural region, disposed distally relative to the first structural region, defining a second series of wall perforations that generate structural properties within the second structural region, the second series of wall perforations setting a second stiffness of the second structural region, which is less than the first stiffness, wherein the second series of wall perforations differs from the first series of wall perforations by at least one of: cut balance, cut frequency, or pitch.
