TISSUE GRASPING DEVICES AND RELATED METHODS
A prosthetic device for sealing a native heart valves to prevent or reduce regurgitation comprises a spacer having one or more anchors. The spacer may also have atrial support structures, ventricular support structures, or both atrial and ventricular support structures In some cases, the spacer has anchors that attach to the leaflets as well as atrial and ventricular support. In some cases, the spacer straddles the annulus and is located by anchors, and in some cases the support structures can be implanted within the native heart valve. In some cases, the prosthetic device reduces the annulus diameter when implanted within the native heart vasculature. In some cases, the prosthetic device cinches the annulus when implanted within the native heart vasculature.
SEPTAL CROSSING SYSTEM
A septal cross system is provided for a cerclage procedure for treating dysfunctional heart. The cerclage septal cross system includes a puncture catheter and a capture catheter. The puncture catheter a puncture catheter comprises a first lumen for a guidewire to be inserted thereinto. A coil element is arranged in the distal portion of the puncture catheter. The distal end of the pull-wire is attached to the distal portion of the coil element. The proximal end of the pull-wire is extended to the distal portion of the puncture catheter. The pull-wire is configured to bend inwardly the distal portion of the puncture catheter. A capture catheter comprises a first lumen for a first guidewire to be inserted thereinto and a second lumen for a second guidewire to be inserted thereinto. The distal end of the second wire has a snare wherein the distal portion is deflectable.
Perfusion balloon with internal valve
An apparatus for performing a medical procedure and, in particular, an aortic valvuloplasty, in a vessel for transmitting a flow of fluid. The apparatus comprises a shaft, an inflatable perfusion balloon supported by the shaft and including an internal passage for permitting the fluid flow in the vessel while the perfusion balloon is in an inflated condition, and a valve for controlling the fluid flow within the passage. The valve may be connected to the shaft, or may comprise an elongated tube partially connected to the balloon. The balloon may comprise a plurality of cells in a single cross-section, each cell including a neck, and the valve may be positioned in a space between the shaft and the necks for controlling the fluid flow within the passage. A connector may also be provided to control the position of the valve.
METHOD AND APPARATUS FOR MITRAL VALVE CHORD REPAIR
Methods and devices for transvascular prosthetic chordae tendinea implantation are disclosed. A catheter is advanced into the left atrium. From an atrium side, the catheter can be anchored to a superior surface of a mitral valve leaflet and a leaflet anchor can be advanced into the mitral valve leaflet to secure the mitral valve leaflet to a leaflet suture. A ventricular anchor is anchored to the wall of the ventricle to secure the ventricular wall to a ventricle suture. The leaflet suture and the ventricle suture may be tensioned and connected by a suture lock to form an artificial chordae.
DEVICES AND METHODS FOR INCREASING BLOOD PERFUSION TO A DISTAL EXTREMITY
Devices and methods divert blood flow from a first vessel to a second vessel and maintain blood flow in the first vessel. The device includes a first segment and a second segment. The first segment is configured to anchor in the first vessel. The first segment includes a window to allow blood to flow into the first segment, through the window, and distal in the first vessel. The second segment is configured to anchor in the second vessel. The second segment is configured to allow blood to flow into the first segment, through the second segment, and into the second vessel.
Tissue grasping devices and related methods
The present disclosure relates generally to systems, devices, and methods for supporting, stabilizing, and/or positioning a medical device, such as a transcatheter medical device. The stabilizer allows for control of degrees of freedom from no movement to free movement to selective movements, to substantially translation only movement and/or to substantially rotational only movement of the medical device. The patent describes pure mechanical embodiment as well as smart embodiments that can synergistically sense, actuate and/or transmit data between the stabilizer, medical device and control or display system to operate and/or deploy the device/therapy.
SELF-LOCKING WINCH
A system includes a transcatheterally-advanceable driver and an implant. The implant includes a winch, and a tether that has an end portion. The winch includes a spool, a mount, and a driver interface engageable and drivable by the driver. The mount is coupled to the driver interface such that driving of the driver interface by the driver rotates the mount about a rotation axis. The spool is coupled to the tether, and defines a spool axis that is non-coaxial with the rotation axis. The tether extends away from the winch toward the end portion. The spool is fixedly coupled to the mount such that rotation of the mount about the rotation axis draws the end portion of the tether toward the spool by winding the tether around the spool axis of the spool. Other embodiments are also described.
GUIDED ADVANCEMENT OF AN IMPLANT
A tissue-engaging element is advanced to a heart, while coupled to a guide member. The tissue-engaging element is then coupled to tissue of the heart. An elongate implant is subsequently slid distally along the guide member toward the tissue-engaging element, and the elongate implant is subsequently locked to the tissue-engaging element. Other embodiments are also described.
Inflatable medical devices
Inflatable medical devices and methods for making and using the same are disclosed. The inflatable medical devices can be medical balloons. The balloons can be configured to have a through-lumen or no through-lumen and a wide variety of geometries. The device can have a high-strength, non-compliant, fiber-reinforced, multi-layered wall. The inflatable medical device can be used for angioplasty, kyphoplasty, percutaneous aortic valve replacement, or other procedures described herein.
Method and apparatus for mitral valve chord repair
Methods and devices for transvascular prosthetic chordae tendinae implantation are disclosed. A catheter is advanced into the left atrium. From an atrium side, the catheter can be anchored to a superior surface of a mitral valve leaflet and a leaflet anchor can be advanced into the mitral valve leaflet to secure the mitral valve leaflet to a leaflet suture. A ventricular anchor is anchored to the wall of the ventricle to secure the ventricular wall to a ventricle suture. The leaflet suture and the ventricle suture may be tensioned and connected by a suture lock to form an artificial chordae.
