Publication number: 20100298929Abstract: Disclosed are methods, systems, and devices for the endovascular repair of cardiac valves, particularly the atrioventricular valves which inhibit back flow of blood from a heart ventricle during contraction. The procedures described herein can be performed with interventional tools, guides and supporting catheters and other equipment introduced to the heart chambers from the patient's arterial or venous vasculature remote from the heart. The interventional tools and other equipment may be introduced percutaneously or may be introduced via a surgical cut down, and then advanced from the remote access site through the vasculature until they reach the heart.Type: ApplicationFiled: January 19, 2010Publication date: November 25, 2010Inventors: Troy L.

Publication number: 20100274188Abstract: A method for dilating a Eustachian tube of a patient is disclosed. In one embodiment, the method may involve advancing a dilation device through a nasal passage of the patient to position a dilator of the device at least partially in a Eustachian tube of the patient, expanding the dilator to an expanded configuration to dilate a portion of the Eustachian tube, collapsing the dilator, and removing the dilation device from the patient. The dilated portion of the Eustachian tube remains at least partially dilated after removal of the device.Type: ApplicationFiled: May 11, 2010Publication date: October 28, 2010Applicant: ACCLARENT, INC.Inventors: John Y.

Patent number: 7811296Abstract: Devices, systems and methods are provided for tissue approximation and repair at treatment sites, particularly in those procedures requiring minimally-invasive or endovascular access to remote tissue locations. Fixation devices are provided to fix tissue in approximation with the use of distal elements. In some embodiments, the fixation devices have at least two distal elements and an actuatable feature wherein actuation of the feature varies a dimension of the at least two distal elements. In other embodiments, the fixation devices have at least two pairs of distal elements wherein the pairs of distal elements are moveable to engage tissue between opposed pairs of distal elements. Systems are also provided having fixation devices and accessories.Type: GrantFiled: October 27, 2004Date of Patent: October 12, 2010Assignee: Evalve, Inc.Inventors: Eric A. Goldfarb, Alfred H.

Publication number: 20100217283Abstract: The methods, devices, and systems are provided for performing endovascular repair of atrioventricular and other cardiac valves in the heart. Regurgitation of an atrioventricular valve, particularly a mitral valve, can be repaired by modifying a tissue structure selected from the valve leaflets, the valve annulus, the valve chordae, and the papillary muscles. These structures may be modified by suturing, stapling, snaring, or shortening, using interventional tools which are introduced to a heart chamber. Preferably, the tissue structures will be temporarily modified prior to permanent modification. For example, opposed valve leaflets may be temporarily grasped and held into position prior to permanent attachment.Type: ApplicationFiled: May 4, 2010Publication date: August 26, 2010Applicant: Evalve,Inc.Inventors: Frederick G.
