Procedures may be performed on the heart after the installation of a mitral valve fixation device. In order to prepare the heart for such procedures, the fixation device may be removed or disabled in minimally invasive ways (e.g., through an endovascular procedure), without requiring open access to the heart. The fixation device may be partitioned so that one portion may remain attached to each leaflet of the mitral valve. In another example, the leaflets may be cut along the edges of the distal element(s) of the fixation device, so as to cut the fixation device from the leaflet(s). Systems and devices for performing such procedures endovascularly are disclosed. Fixation devices with improved access to a release harness are also disclosed.

Mitral valve fixation device removal devices and methods

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.

Tissue fixation devices and methods

A telescoping access cannula comprising: an outer tube; an inner tube carried by the outer tube, the inner tube being coaxial with the outer tube and longitudinally movable relative to the outer tube; and a rotatable member carried by the outer tube and connected to the inner tube, wherein rotation of the rotatable member causes longitudinal movement of the inner tube relative to the outer tube.

Method and apparatus for accessing the interior of a hip joint, including the provision and use of a novel telescoping access cannula and a novel telescoping obturator

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.

Grasping for tissue repair

Fixation device for fixation of leaflets of a heart valve includes a central assembly and at least one arm moveably coupled relative to the central assembly. The at least one arm includes a deformable frame having a first end and a second end and a longitudinal axis defined therebetween, the second end being moveable between a closed position and an open position. The deformable frame further includes first and second deformable flex portions, each flex portion extending along a respective lateral side of the deformable frame and having a deformed condition and an undeformed condition, and each flex portion having an outer lateral edge. The at least one arm has a maximum deformed arm lateral cross-dimension with the flex portions in the deformed condition.

Wide clip with deformable width

A lubricated tubular graft is implanted in the inferior vena cava and the superior vena cava in order to control the inflow of blood to the right atrium. A bifurcated leg with a non-collapsing stent extends across the tricuspid valve. A bioprosthetic valve is positioned proximal of the stent in the bifurcated leg in order to regulate flow through the tricuspid valve and to eliminate tricuspid regurgitation.

Bifurcated tubular graft for treating tricuspid regurgitation

Medical delivery system for accessing a tricuspid valve via an inferior vena cava, including an outer guide catheter, an inner guide catheter and an interventional catheter. The first deflection portion of the outer guide catheter is steerable to define a first outer-guide-catheter curve and the second deflection portion of the outer guide catheter is steerable to define a second outer-guide-catheter curve and the first deflection portion of the inner guide catheter is steerable to define a first inner-guide-catheter curve.

Devices and systems for accessing and repairing a heart valve

The present disclosure relates to repair devices for repair of regurgitant mitral valves. A repair device includes a body having a perimeter defining an upper side and a lower side. An annular groove is disposed along a posterior section of the perimeter of the device and is configured to receive posterior rim tissue of a mitral valve annulus. First and second anchors extend from the body in an anterior direction. The first and second anchors are configured to engage with respective commissures of the mitral valve to assist in securing the repair device in position. The repair device is structured to minimize or eliminate imparting or transmitting radially outward forces along an anterior section so as to avoid imparting forces to the septum to avoid hindering the function of the aortic valve and the left ventricular outflow tract.
