DEVICE, SYSTEM, AND METHOD FOR TRANSCATHETER TREATMENT OF VALVULAR REGURGITATION
Devices are disclosed for use in the transcatheter treatment of mitral valve regurgitation, specifically a coaptation assistance element for implantation across the mitral valve and an edge to edge device. Methods are disclose for reducing mitral valve regurgitation at low left ventricle pressure and high left ventricle pressure during the cardiac cycle. Devices are disclosed for use in the transcatheter treatment of mitral valve regurgitation, specifically a coaptation assistance element for implantation across the mitral valve with an adaptive coaptation element.
Delivery system with anchoring nosecone and method of delivery
A delivery device includes an inner shaft, an outer sheath, a nosecone, and a tether component. The outer sheath is slidably disposed over the inner shaft. The nosecone is removably coupled to the inner shaft. The nosecone includes a delivery configuration for delivery to a treatment site, a radially compressed configuration in which a portion of the nosecone is configured to traverse through a heart wall, and a radially expanded configuration in which an outer surface of the nosecone contacts an outer surface of the heart wall. The tether component includes a first end coupled to the nosecone. The nosecone is configured to plug a piercing in the heart wall when in the radially expanded configuration.
Device, system, and method for transcatheter treatment of valvular regurgitation
The invention relates to a device for use in the transcatheter treatment of mitral valve regurgitation, specifically a coaptation assistance element for implantation across the valve; a system including the coaptation assistance element and anchors for implantation; a system including the coaptation assistance element and delivery catheter; and a method for transcatheter implantation of a coaptation element across a heart valve.
Apparatus and system for changing mitral valve annulus geometry
Examples of an apparatus, system and method for changing a geometry of a mitral valve of a heart are described herein. In one example embodiment, the apparatus comprises an anchor having a body for positioning and anchoring within a coronary sinus vein of the heart. The body has a first end and a second end that is spaced apart from the first end; a longitudinally extending axis; and a wall with an interior volume extending between the first and second ends, the interior volume being adapted for receiving a steerable catheter. The apparatus also includes a first link member having a proximal end nearest to the anchor and a distal end spaced apart from the proximal end. The proximal end of the first link member is coupled to the anchor by a joint configured to provide for movement of the first link member in one direction relative to the anchor.
Stabilizing and adjusting tool for controlling a minimally invasive mitral / tricuspid valve repair system
Disclosed herein are embodiments related to a method for performing a minimally invasive procedure, the method including delivering an annuloplasty ring in a linear shape using a delivery system. In some embodiments, the delivery of the annuloplasty ring may utilize a trans-septal approach or a trans-apical. In some embodiments, the delivery system may position the annuloplasty ring using a flexible stabilizing mechanism and/or activate one or more anchors to extend outward from the annuloplasty ring.
Devices and systems for accessing and repairing a heart valve
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.
PROSTHETIC CARDIAC VALVE DELIVERY DEVICES, SYSTEMS, AND METHODS
A device and system for use with medical devices, such as catheter devices or systems. The device or system comprises an anchor for securing to tissue. The anchor comprises a series of segments that allow the anchor to be actuated from a delivery configuration to a deployed configuration. The anchor may include a tie band and a free end. In some examples, the device or system is used in treating a diseased native valve in a patient. The anchor may part of a delivery device to implant a prosthetic valve. Subsequent to delivery, the components of the delivery device are actuated to secure the prosthetic valve within the diseased valve.
Beating-heart mitral valve chordae replacement
Methods and devices for the treatment of cardiac valve dysfunction through the placement of lines and anchors. The lines and anchors can form artificial chordae between valve leaflets and the ventricular wall or papillary muscles or connect the two valve leaflets together. The methods and devices offer a mechanism for performing this technique with the heart still beating, and allows for the placement of multiple lines with a single device.
Device that can be implanted in a minimally invasive manner and mitral valve implant system
The invention relates in general to the field of heart surgery. In the surgical field, instruments are used in order to examine the interior of living organisms and/or to use for operative interventions. These also include implants for the production of the functionality of a heart. The invention relates to such an implantable device and a method for eliminating regurgitation in the area of the heart. The implantable device is an annuloplasty ring with a large number of tissue anchors. An unfolded annuloplasty ring is positioned in the cavity of a body element in order to constrict a bodily opening. Using the minimally-invasive technique, each tissue anchor of the annuloplasty ring is intravascularly inserted in advance into a precise position on the edge of the mitral valve annulus. The annuloplasty ring that is configured in the shape of an arc or circle is mounted and fastened to the thus anchored fastening means in order to influence in size and shape the septal and lateral annulus of the mitral valve and to close the gap between the anterior and posterior cusps in the valve.
Surgery for correcting tricuspid valve regurgitation
A method is presented for tricuspid valve commissural annuloplasty for secondary tricuspid insufficiency. The method comprises suturing through a valve annulus, and bringing the valve annulus to its normal size while eliminating its regurgitation. The suturing comprises applying individual sutures on pledgets through the tricuspid valve annulus from a right ventricle side along anteroposterior and posteroseptal commissures on both sides of each of said commissures, spaced-apart from them; taking out needles of said sutures from a right atrium side and tying knots along the commissures between them.
