  • Publication number: 20240415646
    Abstract: Delivery systems, devices, and methods for delivering a valve prosthesis to a native valve annulus are provided. The valve prosthesis may be secured to the native valve via an anchor that encircles the native valve annulus and the valve prosthesis. The anchor may be deployed around the chordae tendinea and/or leaflets of the native valve. A tether may be connected to the anchor and extend outside of the patient's body to maintain communication with the anchor. After the anchor is deployed, a guidewire may be advanced through the patient's vessels parallel to the tether and through the native valve annulus. A valve delivery catheter carrying the valve prosthesis may be advanced over the guidewire and into the native valve annulus where the valve prosthesis is released and deployed. The tether may be used to position the anchor and/or valve prosthesis during one or more operations of the valve delivery process.

  • Publication number: 20220249285
    Abstract: The present technology is directed to systems for treating medical conditions, such as glaucoma, and associated devices and methods. For example, in some embodiments the present technology includes an adjustable flow shunt and a sensor. When implanted in a patient, the adjustable flow shunt can be configured to fluidly couple a first body region with a second body region such that it directs the flow of fluid from the first body region to the second body region. When implanted in the patient, the sensor can measure a physiologic parameter, such as intraocular pressure. The adjustable flow shunt can be adjusted based on the measurements taken by the sensor.
