Abstract
Devices, systems and methods for treating diseases and disorders effecting the cardiovascular system of the human body are disclosed. An exemplary device 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.
Claims20
A re-entry device, comprising:
- an elongate shaft;
- a tip member attached to a distal segment of the elongate shaft;
- a helical coil having a proximal end attached to the elongate shaft and a distal end attached to the tip member;
- and
- a probe extending distally beyond a distal surface of the tip member;
- wherein the re-entry device is biased to assume a bent shape including a bend disposed along the distal segment.

A system for treating an occluded vessel, comprising:
- an orienting device including an elongate tubular member having a side wall defining a central lumen and a first aperture extending through the side wall to communicate with the central lumen;
- wherein the orienting device includes an orienting element coupled to the elongate tubular member and configured to orient the first aperture toward a true lumen of the occluded vessel;
- and
- a re-entry device comprising an elongate shaft, a tip member attached to a distal segment of the elongate shaft, a helical coil having a proximal end attached to the elongate shaft and a distal end attached to the tip member, and a probe extending distally beyond a distal surface of the tip member;
- wherein the re-entry device is biased to assume a bent shape including a bend disposed along the distal segment.
