Abstract
Devices, systems and methods for treating diseases and disorders effecting the cardiovascular system of the human body are disclosed. An exemplary blood vessel in accordance with this disclosure comprises a shaft, tip member fixed to the shaft, and a probe extending beyond a distal surface of the tip member. In some useful embodiments, the tip member is relatively atraumatic and the probe is shaped so as to be more likely to produce trauma than the tip member.
