Publication number: 20240008985Abstract: Devices for treating a native valve annulus are disclosed herein. In some examples, the present technology includes a device comprising a plurality of arms configured to move independently of one another and a coupler coupled to the arms and configured to move relative to the arms. The device can further include a plurality of anchors, each carried by the distal portion of one of the arms and configured to engage tissue at or proximate the annulus. When the device is in a deployed configuration such that the arms extend axially and radially away from the coupler, movement of the coupler relative to the arms may decrease a circumferential distance between at least some of the anchors.Type: ApplicationFiled: April 10, 2023Publication date: January 11, 2024Inventors: Shih-hsiung Albert Yuan, Ashley C. Pittner, Jordan M. Skaro

Publication number: 20220395362Abstract: Disclosed are methods and devices for isolating all three of the left subclavian, left common carotid and brachiocephalic arteries from embolic debris that might flow through the aortic arch, via a single access point. A system may include an elongate flexible tubular sheath, having a proximal end and a distal end, and an inner member extending through the sheath and moveable relative to the sheath. A left subclavian element may be supported by the inner member. A filter membrane may be configured to isolate the aorta from the brachiocephalic, left common carotid and left subclavian arteries when the left subclavian element is expanded within the left subclavian artery and the sheath is retracted to expose the membrane. The left subclavian element may include a self expandable frame, which may carry a left subclavian filter.Type: ApplicationFiled: August 22, 2022Publication date: December 15, 2022Applicant: Claret Medical, Inc.Inventors: Whittaker Ian Hamill, Shih Hsiung Albert Yuan, Antony J. Fields, Cameron Paul Purcell, Daniel Wayne Fifer, James Richard Watson

Publication number: 20200345980Abstract: Described here are devices, methods, and kits for the deployment of tissue anchors. In some variations, the devices may comprise a shaft defining a lumen for housing at least one anchor therein and a mechanism for deploying the anchor distally from the lumen. In certain variations, the devices may comprise one or more stop elements. For example, a device may comprise a stop element that limits the advancement of the device through an opening in a wall portion or at the distal end of another device.Type: ApplicationFiled: April 20, 2020Publication date: November 5, 2020Inventors: Eugene SERINA, Stephen C.

Publication number: 20140072695Abstract: A system and method for coating an expandable member of a medical device comprises providing a dispenser in fluid communication with a fluid source with the dispenser having at least one outlet to dispense fluid of the fluid source therefrom. The outlet(s) of the dispenser is positioned proximate a surface of an expandable member, with relative movement between the outlet(s) and the surface of the expandable member established along a coating path, and fluid is dispensed from the dispenser to form a substantially continuous bead of fluid between the at least one outlet and the surface of the expandable member along the coating path, and simultaneously drying the fluid while dispensing the fluid from the dispenser to control flow of fluid on the surface of the expandable member. The fluid source can include a variety of therapeutic agents.Type: ApplicationFiled: November 12, 2013Publication date: March 13, 2014Applicant: Abbott Cardiovascular Systems Inc.Inventors: Victoria M.
