DEVICE FOR IMPROVING CARDIAC FUNCTION
The present disclosure provides methods of improving cardiac function, including transcutaneously inserting at least one catheter into a heart, delivering a band to a ventricle of the heart via the at least one catheter, guiding the band through a plurality of spaces among a trabeculae in the ventricle, tightening the band in a single loop, locking the band in a loop, and removing the at least one catheter from the heart.
Adjustable heart valve implant
Systems and methods are provided for repairing a heart valve, such as a mitral, tricuspid or aortic valve, using an adjustable and removable implant that can be delivered to the heart through the apex in a simplified and non-invasive manner. The implant can include a prosthetic valve portion coupled to a proximal end of a shaft, and an anchor portion coupled to a distal end of the shaft. The prosthetic valve can be suspended within an opening of the heart valve while the anchor portion is affixed to the apex of the heart. When the implant is deployed, a distance between the prosthetic valve portion and the anchor portion can be adjusted, and/or the implant or a portion thereof can be rotated to thereby change the position of the prosthetic valve within the heart valve. This can allow correcting for post-implantation movements of the implant to mitigate potential complications.
Percutaneous papillary muscle relocation
A system for treating mitral regurgitation may include an outer sheath having a lumen extending to a distal end of the outer sheath, an intermediate sheath slidably disposed within the lumen of the outer sheath, the intermediate sheath having a lumen extending to a distal end of the intermediate sheath, and an inner sheath slidably disposed within the lumen of the intermediate sheath, wherein the inner sheath includes a first anchor disposed within a lumen of the inner sheath, the first anchor being configured to penetrate and secure to a first papillary muscle. The intermediate sheath may include a tissue grasping mechanism at the distal end of the intermediate sheath, the tissue grasping mechanism being configured to hold and stabilize the first papillary muscle for penetration and securement of the first anchor to the first papillary muscle.
Methods for occluding or promoting fluid flow
Devices and methods for occluding or promoting fluid flow through openings are disclosed. In one exemplary embodiment an occlusion device is provided having an expandable outer elongate tubular body, a guide member extending from a distal end of the outer body, and a slide tube disposed within the outer body, the proximal portions of the outer body and the slide tube being fixedly mated. The slide tube is configured to slide distally within the outer tubular body when the tubular body is expanded to form wings. A tether can be included as part of the device and it can be used to assist in positioning and locking a location of the device in an opening. Exemplary methods for delivering devices disclosed herein are also provided.
Prosthetic heart valve devices and methods of valve replacement
A stented valve having at least one leaflet made of pericardium or other material having a relatively thin profile at the annulus. The leaflets are attached via chords to a stent frame, where the chords are positioned to mimic the native valve anatomy and functionality. In particular, the valves of one exemplary embodiment of the invention are sized to replace a mitral valve and therefore the chords are arranged to prevent prolapse of the leaflets into the atrium. The stented valve has a relatively short height at its annulus due to the positioning of the chords. In addition, the stented valve is capable of being crimped to a small enough size that it can be delivered to the implantation site via transcatheter delivery systems and methods.
Tethers for prosthetic mitral valve
This invention relates to the design and function of a single-tether compressible valve replacement prosthesis which can be deployed into a beating heart without extracorporeal circulation using a transcatheter delivery system. The design as discussed combats the process of wear on anchoring tethers over time by using a plurality of stent-attached, centering tethers, which are themselves attached to a single anchoring tether, which extends through the ventricle and is anchored to a securing device located on the epicardium.
Method and device for treating dysfunctional cardiac tissue
Various methods and devices are provided for reducing the volume of the ventricles of the heart. In one embodiment, a method for reducing the ventricular volume of a heart chamber is provided including the steps of inserting an anchoring mechanism onto dysfunctional cardiac tissue, deploying one or more anchors into the dysfunctional cardiac tissue, raising the dysfunctional cardiac tissue using the anchors, and securing the anchors to hold the dysfunctional cardiac tissue in place. Further, a device for reducing the volume of the ventricles of a heart chamber is provided where the device has one or more clips for placement on dysfunctional cardiac tissue of a heart, one or more anchors for deployment and securement into the dysfunctional cardiac tissue, and a lifting mechanism for raising the one or more anchors and the dysfunctional cardiac tissue.
Heart Valve Implant And Methods For Delivering And Implanting Same
Heart valve implants and methods for implanting and delivering same are described. A heart valve implant can include a shaft, having a first end and a second end, an anchor, and a plurality of wafers. The anchor is coupled to the first end of the shaft and configured to secure the heart implant to a patient's heart. The wafers are coupled to the second end of the shaft and configured to form a stacked array of wafers. The stacked array of wafers can partially reduce a flow of blood through a heart valve upon coming in contact with a portion of a leaflet of the heart valve.
VENTRICULAR REMODELING USING COIL DEVICES
A coil device for treating a heart valve includes a wire with a distal end and a proximal end with a cloth configured to promote ingrowth of tissue into the cloth covering at least a portion of the wire. The wire is formed at least partially from a memory metal that is pre-shaped to assume a helical coil shape with a diameter designed to provide a constricting force on a ventricle wall of a heart when the coil device is woven behind tissue features of trabeculae carneae associated with the ventricle wall.
PERCUTANEOUS HEART VALVE PROSTHESIS
A percutaneous heart valve prosthesis (1) has a valve body (2) with a passage (9) extending between the first and second ends (7, 8) of the valve body (2). The valve body (2) is collapsible about a longitudinal axis (10) of the passage (9) for delivery of the valve body (2) via a catheter (18). One or more flexible valve leaflets (3, 4) are secured to the valve body (2) and extend across the passage (9) for blocking bloodflow in one direction through the passage (9). An anchor device (5), which is also collapsible for delivery via catheter (18), is secured to the valve body (2) by way of an anchor line (6).
