  • Publication number: 20240341988
    Abstract: A pyloric implant generally includes a stomach portion, a duodenal portion and a pyloric portion extending between the two. A channel extends through the implant to allow food to pass from the stomach, through the pylorus, into the duodenum. The stomach and duodenal portions expand from a delivery configuration to a deployed configuration, upon release from a delivery device, in order to anchor the implant within the stomach, pylorus and duodenum. The pyloric implant slows the passage of food out of the stomach, through the pylorus, thus promoting weight loss.

  • Patent number: 11918729
    Abstract: Methods, devices, and systems for laser eye surgery generally make use of a console that interchangeably accepts multiple types of eye treatment cassettes. The cassettes enable one or both of displacement-based or vacuum-based aspiration. The console and the cassette may communicate to establish the functionality of the installed cassette by utilizing a component indigenous to the operation of the cassette. A dual-mode cassette may include a separable holding tank for enabling vacuum-based aspiration. A displacement-based pump may be provided to drain the holding tank while the vacuum system continues to aspirate fluids. A vacuum sensor for controlling the flow of aspirated fluids may have three ports for communicating with a handpiece, a displacement-based pump, a vacuum-based pump, or an irrigation source. The handpiece may be vented during vacuum-based aspiration by opening a vent valve interposed between the handpiece and the vacuum source.

  • Publication number: 20230210540
    Abstract: Systems, methods, and devices for treating vascular defects are disclosed herein. In some embodiments, a method of treating an aneurysm includes positioning a distal portion of an elongated member near or within an aneurysm. The method can include introducing an embolic composition into a lumen of the elongated member using an injector device coupled to a proximal portion of the elongated member. The injector device can pressurize the embolic composition to a pressure of at least 10,000 psi. The method can also include delivering the embolic composition into the aneurysm via the elongated member.

  • Patent number: 10668191
    Abstract: Devices, systems, and methods for treatment of an eye alter aspiration flow from the eye in response to an occlusion of the aspiration conduit pathway. Where aspiration is drawn from the eye using a volumetric pump, the pump can be reversed so as to induce fluid reflux from the aspiration conduit pathway into the eye to help clear the occlusion. The pump may vary the reverse flow in response to sensed aspiration pressure or the like, and the reverse flow may be halted before the pressure within the aspiration conduit pathway adjacent the eye significantly exceeds the irrigation fluid pressure and/or the pressure within the eye. Reflux may alternatively be generated by modulating a vent valve disposed between an irrigation conduit pathway and the aspiration conduit pathway.

  • Patent number: 9522221
    Abstract: An eye treatment cassette includes a handpiece, a vacuum source, a holding tank, a collection bag, and a displacement-based pump. The handpiece is configured to aspirate fluids from a patient's eye. The vacuum source communicates with the handpiece. The holding tank is interposed between the handpiece and the vacuum source, and is configured to hold the aspirated fluids. The collection bag is connected to the holding tank for collecting the aspirated fluids. The pump is coupled to the holding tank and is configured to operate while the vacuum source continues to aspirate fluids via the handpiece to drain the aspirated fluids from the holding tank.
