Apparatus and methods for delivery of a prosthetic valve within an existing implanted prosthetic valve
Apparatus and methods are described herein for a secondary valve apparatus that can be deployed within an existing implanted prosthetic heart valve. In some embodiments, a secondary prosthetic heart valve apparatus is implanted in series with an existing deteriorating implanted prosthetic valve. The secondary valve apparatus can restore proper valve function without disruption to the failing previously implanted valve. In some embodiments, the secondary valve apparatus can be positioned on an atrial portion of the existing valve, and be delivered transseptally. In other embodiments, the secondary valve apparatus can be positioned at a ventricular portion of the existing valve and delivered transapically. Devices and methods to prepare the existing valve to receive a secondary valve apparatus are also described herein. In some embodiments, a balloon expansion device can be used to expand an inner diameter of the existing valve to provide space for the secondary valve to be disposed.
METHOD AND APPARATUS FOR EXTERNAL STABILIZATION OF THE HEART
The present disclosure is directed to an external cardiac basal annuloplasty system (ECBAS or BACE-System: basal annuloplasty of the cardia externally) and methods for treatment of regurgitation of mitral and tricuspid valves. The BACE-System provides the ability to correct leakage of regurgitation of the valves with or without the use of cardiopulmonary bypass, particularly when the condition is related to dilation of the base of the heart. This ECBAS invention can be applied to the base of the heart epicardially, either to prevent further dilation or to actively reduce the size of the base of the heart.
Intra-Operative Heart Size Measuring Tool
A heart size measuring tool includes a tubular body, a flexible measuring cord having length indicia, a measuring cord support mechanism movable between retracted and extended states with respect to the body, and an actuating mechanism to move the measuring cord support mechanism. When in the retracted state the measuring cord support mechanism is positioned within the tubular body with the measuring cord in a collapsed position. When the measuring cord support mechanism is in the extended state the measuring cord extends around a portion of a heart to be measured. A scale on the body can be used in connection with the indicia on the measurement cord to provide a reading of the heart size.
Epicardial Clip
An epicardial clip for reshaping the annulus of the mitral valve of a heart includes a curved member having an anterior segment configured to be positioned in the transverse sinus of the heart, a posterior segment configured to be positioned on the posterior side of the heart, such as on or inferior to the atrioventricular groove, and a lateral segment extending between the anterior segment and the posterior segment. The lateral segment includes a curve such that the first end of the member is positioned at or above the plane of the mitral valve and the second end of the member is positioned at or below the plane of the mitral valve.
Expandable Anchor For Prosthetic Mitral Valve
A prosthetic heart valve system may include a prosthetic heart valve, a tether having a first end configured to connect to the prosthetic heart valve and a second end, and a collapsible and expandable anchor. The anchor includes a center rim configured to couple to the second end of the tether. The anchor further includes a plurality of struts extending radially outward from the center rim forming an inner dome that is concave toward a heart when the anchor is in a resting configuration implanted on an apex of the heart. The anchor further includes a plurality of wings extending radially outward from the struts.
Cardiac compression device having passive and active chambers
The present invention provides methods, systems, kits, and cardiac compression devices that have both passive chambers and active chambers to improve heart function.
Cardiac Compression Device Having Passive And Active Chambers
The present invention provides methods, systems, kits, and cardiac compression devices that have both passive chambers and active chambers to improve heart function.
Heart shape preserving anchor
Embodiments of a heart shape preserving anchor are disclosed herein. The heart shape preserving anchor can include a frame having one or more wings extending from a lower end of the frame. The frame can be sized and shaped to distribute forces over a large surface area thereby reducing pressures applied on the heart. The anchor can include a tether for coupling to a prosthesis, such as a replacement heart valve prosthesis. In some embodiments, the anchor can include a tether adjustment mechanism which can be wirelessly operated to adjust a length of the tether relative to the frame.
Percutaneous arterial access to position trans-myocardial implant devices and methods
A system for treating a heart includes a catheter that is advanceable into a chamber of the heart and that is repositionable within the chamber between a septal wall and an external wall to enable penetration of the septal and external walls via a needle that is disposed within a lumen of the catheter. A first guidewire is deliverable through the penetration of the septal wall so that a distal end of the first guidewire is disposed within another chamber of the heart. A second guidewire is deliverable through the penetration of the external wall so that a distal end of the second guidewire is disposed externally of the external wall. The first guidewire is connectable to the second guidewire to join or form a path within the chamber that extends between the septal wall and the external wall.
Adjustable self-locking papillary muscle band
Embodiments of the present disclosure include a cardiac device comprising a band configured for deployment within a heart. The band may include a first end and a second end, an actuatable clasp associated with the first end of the band and configured to transition, upon actuation, from an open configuration to a closed configuration for forming the band into a fixed length loop after the second end is moved beyond the clasp. The clasp may be configured for actuation via a catheter. The cardiac device may include a clasp retainer associated with the clasp, the clasp retainer being configured to hold the clasp in the open configuration and the clasp being configured to be actuated upon movement of the clasp retainer, and a clasp actuator configured to move the clasp retainer thereby actuating the clasp.
