Publication number: 20200306034Abstract: Methods of implanting docking devices for prosthetic valves at a native heart valve include positioning a distal end of a delivery catheter into a first chamber of a heart, advancing a tubular body of a docking device from within the delivery catheter so that the distal end of the tubular body is advanced between native valve leaflets and positioned in a second chamber of the heart. The methods further include inserting a coil into a lumen of the docking device so that the tubular body adopts a configuration, releasing a proximal end of the docking device in the first chamber, inserting a replacement valve in an inner space of the docking device, and radially expanding the replacement valve until there is a retention force between the replacement valve and the docking device to hold the replacement valve in a stable position in the native valve.Type: ApplicationFiled: June 16, 2020Publication date: October 1, 2020Inventors: Darshin S.

Patent number: 10758341Abstract: A system is in various embodiments configured to treat a native heart valve, such as to secure a prosthetic heart valve within a native valve. Embodiments of the system include a docking device with different coil portions, such as an upper coil and a lower coil, where the device is configured to assume an axially expanded state and an axially compressed state. In the axially expanded state, the entire upper coil can be positioned on a first side of the lower coil relative to the central axis and/or the entire upper coil and the entire lower coil have a positive pitch relative to each other. In the axially compressed state, at least a portion of the upper coil can be positioned on a second side of at least a portion of the lower coil opposite to the first side relative to the central axis and/or at least a portion of the upper coil has a negative pitch relative to at least a portion of the lower coil.Type: GrantFiled: May 8, 2018Date of Patent: September 1, 2020Assignee: Edwards Lifesciences CorporationInventors: David Maimon, Hernan Altman

Patent number: 10687938Abstract: Docking devices can be configured to be positioned at a native valve of a human heart to provide structural support for docking a prosthetic valve. The docking devices generally have coiled structures that define an inner space in which the prosthetic valve can be held. Some docking devices can be adjusted from a first wider configuration which facilitates easier advancement of the docking device around the valve anatomy, to a second narrower configuration after the docking device has been delivered to more securely hold the prosthetic valve. The docking device may also be better held in position at the native valve after adjustment to the narrower configuration. Some docking devices include a stabilization segment or double coil configuration, where a main coil region is configured to securely hold a prosthetic valve, while a stabilization coil region is configured to more stably hold the docking device at the native valve.Type: GrantFiled: August 23, 2017Date of Patent: June 23, 2020Assignee: Edwards Lifesciences CorporationInventors: Darshin S. Patel, Hernan Altman, Boaz Manash, Tamir S. Levi, Dinesh L. Sirimanne
