  • Patent number: 11950799
    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.

  • Patent number: 11911574
    Abstract: A catheter system for imparting pressure to induce fractures at a treatment site within or adjacent a blood vessel wall includes a catheter, a fortified balloon inflation fluid and a first light guide. The catheter includes an elongate shaft and a balloon that is coupled to the elongate shaft. The balloon has a balloon wall and can expand to a first expanded configuration to anchor the catheter in position relative. The fortified balloon inflation fluid can expand the balloon to the first expanded configuration. The fortified balloon inflation fluid includes a base inflation fluid and a fortification component. The fortification component reduces a threshold for inducing plasma formation in the fortified balloon inflation fluid compared to the base inflation fluid. The fortification component can include at least one of carbon and iron. The first light guide is disposed along the elongate shaft and is positioned at least partially within the balloon.

  • Publication number: 20230277810
    Abstract: A catheter system for pressure wave and inertial impulse generation for intravascular lesion disruption includes a balloon coupled to an elongate shaft, and a first and second light guide disposed along the elongate shaft. The first and second light guides each include a diverting feature in optical communication with at least one light window to direct light to exit each light guide toward a side surface portion thereof and toward the balloon. A method includes expanding the balloon from a collapsed configuration to a first expanded configuration, and activating a light source in optical communication with each light guide to provide sub-millisecond pulses of light to the diverting features, thereby inducing plasma formation in a balloon fluid, causing rapid bubble formation, and imparting pressure waves upon the treatment site.

  • Patent number: 11660427
    Abstract: A catheter system for imparting pressure to induce fractures in a vascular lesion within or adjacent a vessel wall, includes a catheter and a superheating system. The catheter can advance to the vascular lesion. The catheter includes an elongate shaft and a balloon coupled to the elongate shaft. The balloon includes a balloon wall. The balloon moves between a collapsed configuration and a first expanded configuration suitable for anchoring the catheter in position relative to a treatment site. The superheating system can heat a balloon fluid within the balloon rapidly enough to achieve spontaneous vaporization of the balloon fluid and to generate inertial bubbles and acoustic pressure waves. The superheating system can include a first light guide extending along the elongate shaft. The first light guide is in optical communication with a light source at a proximal portion of the first light guide.

  • Patent number: 11497898
    Abstract: Catheters with weeping balloons can be used for various medical purposes. For example, in some embodiments provided herein weeping balloons are used for catheter visualization devices. In some embodiments, weeping balloons are used to deliver therapeutic agents. Weeping balloons can include openings of a selected size and shape through which a fluid gradually flows or “weeps.” The design of the openings can affect performance characteristics such as, but not limited to, fluid flow rate, tear resistance, and mitigation of counter-flow.
