  • Patent number: 10441407
    Abstract: A primary stent-graft is deployed into a primary vessel to exclude an aneurysm. To maintain perfusion to a branch vessel covered by the primary stent-graft, a gutter filling stent-graft is deployed in parallel to the primary stent-graft. The gutter filling stent-graft includes a balloon that is pressurized and inflated by the patient's own blood thereby sealing any gutters formed around the gutter filling stent-graft. By sealing the gutters, the chance of type I endoleaks, migrations, and overall failure to exclude the aneurysm is minimized.

  • Patent number: 10433993
    Abstract: A delivery system includes an elongated shaft component, a self-expanding valve prosthesis, at least one cinching suture, and a radially-expandable sleeve. The valve prosthesis is disposed over a distal portion of the elongated shaft component and includes a compressed configuration for delivery and an expanded configuration for deployment. The at least one cinching suture removably couples the valve prosthesis to the elongated shaft component and radially compresses the valve prosthesis into the compressed configuration for delivery. The sleeve is secured to and encircles an outer surface of the valve prosthesis. The sleeve has a delivery state with a first diameter extending over a full length of the valve prosthesis in the compressed configuration and a deployed state with a greater second diameter extending over the full length of the valve prosthesis in the expanded configuration. The sleeve is configured to prevent paravalvular leakage in situ in the deployed state.

  • Patent number: 10433995
    Abstract: A delivery system for delivering a prosthesis includes a housing, a sheath extending from within the housing, a first motor housed within the housing, a first battery coupled to the first motor, a second motor housed within the housing, a second battery coupled to the second motor, and an actuator accessible from an exterior of the housing. The actuator is coupled to the first and second batteries to selectively activate the first and second batteries to power the first and second motors, respectively. A first pulley is coupled to the first motor such that the first pulley rotates during operation of the first motor and a second pulley is coupled to the second motor such that the second pulley rotates during operation of the second motor. Actuation of the actuator causes at least one of the first and second motors to rotate, thereby causing at least one of the first and second pulleys to wind up a portion of a single continuous cable and retract the sheath.

  • Patent number: 10420642
    Abstract: Disclosed embodiments and methods provide solutions for coupling and decoupling of a delivery device from a stented prosthetic heart valve with one or more release mechanisms. In situations when one or more sutures get tangled or caught upon attempted retraction of the delivery device and sutures after deployment of the stented prosthetic heart valve, a secondary release mechanism can be provided to sever the suture(s) or release the suture(s) from the delivery device. Exemplary secondary release mechanisms include high resistance inserts, cutters and balloon expandable devices. Methods of releasing the sutures from the delivery device or severing the suture(s) are also disclosed.

  • Patent number: 10413411
    Abstract: A device for percutaneously delivering a stented prosthetic heart valve. The device includes an inner shaft assembly, a delivery sheath assembly, an outer stability tube, and a handle. The sheath assembly is slidably disposed over the inner shaft, and includes a capsule and a shaft. The capsule compressively contains the prosthesis over the inner shaft. The stability tube is slidably disposed over the delivery sheath, and includes a distal region configured to be radially expandable from a first shape having a first diameter to a second shape having a larger, second diameter. In a first delivery state, the distal region assumes the first shape, providing a low profile appropriate for traversing a patient's vasculature. In a second delivery state, the distal region has the expanded diameter second shape, sized to receive the capsule, such as when retracting the capsule to implant the prosthesis.

  • Patent number: 10413709
    Abstract: A dilatation catheter includes a high-pressure balloon component comprising an inner balloon and an outer balloon. An interior of the inner balloon is in fluid communication with a lumen of the catheter for receiving inflation fluid therefrom. The outer balloon defines a separate interior within which the inner balloon is disposed. The outer balloon has a hole in a wall thereof for venting the interior of the outer balloon to ambient environment. Proximal necks of the inner and outer balloons are bonded to an outer shaft of the catheter and distal necks of the inner and outer balloons are bonded to an inner shaft of the catheter. In accordance with embodiments hereof, the interior of the outer balloon is not in fluid communication with the interior of the inner balloon, the lumen of the catheter or any other source of fluid from the catheter.

  • Publication number: 20190275295
    Abstract: A balloon catheter including a catheter shaft, a balloon and a support assembly. The catheter shaft defines an internal shoulder and carries the balloon. The support assembly includes a first member and a second member. The second member defines opposing, leading and trailing ends, and is arranged over the first member such that the leading end is distal the trailing end. The leading end is free of direct physical attachment to the first member. The support assembly extends within a lumen of the catheter shaft and the leading end bears against the internal shoulder. A pushing force applied at a proximal region of the catheter shaft is transferred onto the internal shoulder via the support assembly. The support assembly is simple and inexpensive. Further, the leading end of the second member is transversely moveable relative to the first member, thereby minimizing possible kinking of the first member.

  • Patent number: 10406012
    Abstract: A delivery system for delivering a prosthesis includes a housing, a sheath extending from within the housing, a first rotatable knob, a first pulley coupled to the first rotatable knob so as to be rotatable therewith, a second rotatable knob, a second pulley coupled to the second rotatable knob so as to be rotatable therewith, and a cable coupled to the first pulley and to the second pulley. The cable is coupled to a proximal portion of the sheath. Rotation of the first rotatable knob causes the first pulley to rotate while the second pulley remains stationary thereby causing the first pulley to wind up a portion of the cable and retract the sheath at a first speed. Rotation of the second rotatable knob causes both the first and second pulleys to rotate, thereby causing both the first and second pulleys to wind up a portion of the cable and retract the sheath at a second speed being faster than the first speed.

  • Publication number: 20190254816
    Abstract: Methods of transcatheter delivery of a prosthetic heart valve. A distal region of a guide member assembly is advanced into a heart of a patient. The distal region is docked to native anatomy of the heart. A delivery device, including a collapsed prosthetic heart valve, is advanced over the docked guide member assembly. The collapsed prosthetic heart valve is located at an implantation site. The prosthetic heart valve is deployed from the delivery device, and then the delivery device is removed from the patient. At least a portion of the guide member assembly is removed from the patient. In some embodiments, the docking structure is docked to one or more of native mitral valve leaflets, chordae in the left ventricle, or walls of the left ventricle as part of a transseptal mitral valve delivery procedure.

  • Patent number: 10368988
    Abstract: Embodiments hereof relate methods of delivering a valve prosthesis to an annulus of a native valve of a heart. A valve delivery system is introduced into a ventricle of the heart via a ventricular wall of the heart. The valve delivery system has a displacement component at the distal portion thereof. The valve prosthesis is in a delivery configuration and the displacement component is in a delivery state in which the displacement component has a first outer diameter. While the valve prosthesis is in the delivery configuration, the displacement component of the valve delivery system is radially expanded into an expanded state in which the displacement component has a second outer diameter greater than the first outer diameter. The valve delivery system is advanced towards the annulus of the native valve of the heart with the displacement component in the expanded state to displace chordae tendineae.
