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. The gastric bypass device may be deployed using a variety of methods including a push-pull wire method, a rail method, a garage method, a two-piece method and a comprehensive method.

Abstract: A catheter system for pressure wave and inertial impulse generation for intravascular lesion disruption at a treatment site includes a catheter including an elongate shaft and balloon coupled to the elongate shaft. The catheter system includes a light guide disposed along the elongate shaft and at least partially within the balloon, where the light guide is in optical communication with a light source and a balloon fluid. The catheter can include a first focusing element located at a distal portion of the light guide and in optical communication with the light source. The first focusing element can direct light from within the light guide to a first location at a first distance away from the distal portion of the light guide to initiate plasma formation in the balloon fluid away from the distal portion and to cause rapid bubble formation, thereby imparting pressure waves at the treatment site.

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.

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.
