Abstract: A gastric bypass device includes an occlusion device that is adapted to be deployed relative to a patient's pyloric sphincter, an anastomosis anchor that is adapted to be deployed relative to an anastomosis between the patient's stomach and their small intestine, and a tether that extends through the patient's small intestine between the occlusion device and the anastomosis anchor. A dynamic leash may be secured relative to the occlusion device and may work in conjunction with the tether to help hold the occlusion device in place.

Abstract: In some aspects, the present disclosure pertains to self-expanding emboli-capturing centering devices for centering a medical instrument in a conduit within a patient. The centering devices comprise (a) an elongate shaft, (b) a self-expanding centering member having an open distal end and an inner surface forming a central lumen with a flared distal portion, the centering member being configured such that a fluid flowing in a distal-to-proximal direction that is received by the open distal end flows proximally along the flared distal portion of the central lumen before exiting the central lumen through one or more openings in a proximal portion of the centering member, and (c) a filter material configured to filter the fluid received by the open distal end of the centering member. Other aspects of the present disclosure pertain to systems and methods employing such centering devices.

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.

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. The first light guide is in optical communication with a light source and the fortified balloon inflation fluid. The light source provides sub-millisecond pulses of a light to the first light guide so that plasma formation and rapid bubble formation occur in the fortified balloon inflation fluid, thereby imparting pressure waves upon the treatment site.

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.

CPC classification number: A61M25/10184 , H05B6/108
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.

Abstract: A catheter system includes a catheter having an elongate shaft, a balloon and a light guide. The balloon expands from a collapsed configuration to a first expanded configuration. The light guide is disposed along the elongate shaft and is in optical communication with a light source and a balloon fluid. A first portion of the light guide extends into a recess defined by the elongate shaft. A protection structure is disposed within the recess and is in contact with the first portion of the light guide. The light source provides pulses of light to the balloon fluid, thereby initiating plasma formation and rapid bubble formation within the balloon, thereby imparting pressure waves upon a vascular lesion. The protection structure can provide structural protection from the pressure waves to the first portion of the light guide.
