    Abstract: Embodiments herein relate to systems and methods for intravascular lesion disruption. In an embodiment, a catheter system for imparting pressure to induce fractures upon a vascular lesion within or adjacent a blood vessel wall is included. The system includes a catheter configured to advance to a vascular lesion, the catheter including an elongate shaft that defines at least a first orifice for fluid flow; a balloon, coupled to the elongate shaft, that surrounds the first orifice where the balloon can expand from a collapsed configuration suitable for advancing the catheter through a patient's vasculature to a first expanded configuration suitable for anchoring the catheter in position relative to a treatment site; and a propulsion system configured to propel a fluid from the first orifice toward the balloon wall to create an inertial impulse in a vessel wall to transfer momentum to the vascular lesion. Other embodiments are also included herein.

    Abstract: Balloon catheter and methods for making and using balloon catheters are disclosed. An example balloon catheter may include a proximal shaft. A midshaft may be attached to the proximal shaft. The midshaft may have an outer wall. A distal shaft may be attached to the midshaft. A balloon may be coupled to the distal shaft. An inflation lumen may be defined that extends from the proximal shaft, through the midshaft, and into the distal shaft. The inflation lumen may be in fluid communication with the balloon. A core wire may be disposed within the inflation lumen and may be attached to the midshaft.
