Abstract: The invention provides improved devices, systems, and methods for tissue approximation and repair at treatment sites. The invention provides devices, systems, and methods that may more successfully approximate and repair tissue by improving the capture of tissue into the devices. The invention may be a one-way mechanism that allows tissue to enter the mechanism but not easily exit, such as a leaf-spring, a protrusion, a pivoting arm and one or more frictional elements.

Abstract: The present disclosure describes tissue gripping devices, systems, and methods for gripping mitral valve tissue during treatment of a mitral valve and while a tissue fixation device is implanted in the mitral valve. The tissue gripping device includes a flexible member and one or more tissue gripping members coupled to one or more arms of the flexible member. The flexible member is formed from a shape-memory material, such as nitinol, and the tissue gripping member(s) are formed from a material that is more rigid than the shape-memory material. The tissue gripping member(s) are attached to the flexible member by threading or looping suture lines around and/or through the tissue gripping member(s) and the flexible member and/or by applying a cover material to the tissue gripping device to hold the tissue gripping member(s) against the flexible member.

Abstract: A method for improving function of a cardiac valve in a patient, the cardiac valve having at least one leaflet that is attached to a papillary muscle: Inserting a balloon, that is in a first uninflated condition and having a first diameter, within tissue that is part of to the papillary muscle, and thereby separating tissue that was previously connected together, by a maximum amount equal to the first diameter; inflating the balloon to a second inflated condition having a second diameter greater than the first diameter, thereby permanently stretching tissue in the papillary muscle and separating the tissue from the first diameter to a maximum amount equal to the second diameter; deflating the balloon to the first uninflated condition, and thereby returning the tissue to a separation of a maximum amount substantially equal to the first diameter; and then removing the balloon from the patient.
