  • Patent number: 10806574
    Abstract: A delivery system for percutaneously delivering a heart valve prosthesis to a site of a native heart valve includes a delivery catheter and a heart valve prosthesis. The delivery catheter includes an outer sheath, an inner shaft, and an orifice restriction mechanism. The heart valve prosthesis has a valve member and a docking member. When the orifice restriction mechanism is positioned within the docking member within an annulus of the native heart valve, the orifice restriction mechanism temporarily replicates the operation of the native heart valve until the valve member is positioned within the docking member.

  • Patent number: 10792468
    Abstract: An endovascular guide catheter includes a guide tube and a handle. The flexible guide tube has a distal end portion configured to deflect via actuation of a pull wire. The handle is coupled to the guide tube and comprises a steering assembly configured to actuate the pull wire to deflect the distal end portion of the guide tube. The steering assembly can comprise a stationary rack, a gear, a reel, and a slider. The gear engages the rack and the reel is coupled to and configured to rotate with the gear. The pull wire is coupled to the reel such that rotation of the reel causes the pull wire to wind or unwind around the reel. The slider is adapted for translation relative to the rack. Translation of the slider translates the reel relative to the rack and rotation of the gear along the rack rotates the reel.

  • Publication number: 20200306033
    Abstract: A prosthetic valve including an inner frame, an outer frame, and a connection assembly interconnecting the frames. The inner frame defines an interior volume for receiving a valve structure within the interior volume. The outer frame surrounds the inner frame. The inner and outer frames are each configured to be transitionable between compressed and expanded conditions. The prosthetic heart valve provides a initial deployed state in which the inner and outer frames are in the expanded condition, and a radial shape of the outer frame is adjustable via the connection assembly to a final deployed state. A shape of the outer frame can be adjusted upon implant to enable radial anchoring at the native annulus, while addressing possible non-uniformities of the native annulus and possible anatomical concerns such as LVOT obstruction.

  • Patent number: 10779970
    Abstract: A fenestrated aortic cuff is configured to be delivered endovascularly to a target region, deployed, fastened, and sealed to a vessel wall, e.g., in a neck region of an aortic aneurysm. Example fenestrated cuffs provide a suitable landing zone for a commercially available endograft, which may be, in some cases, positioned below or above the renal arteries in order to complete exclusion of an abdominal aortic aneurysm (AAA) or a thoracic aortic aneurysm (TAA), respectively, from systematic circulation. In some cases, fenestrated cuff function is facilitated and improved by employing active fixation and sealing mechanisms, including, e.g., helical fasteners, which may allow deployment of the fenestrated cuff in short neck regions with limited sealing area.

  • Patent number: 10765513
    Abstract: Delivery devices for a stented prosthetic heart valve. The delivery device includes a spindle, at least one cord, and a lateral control feature. The cord is tensioned to crimp the prosthesis to a compressed condition for delivery to a target site. Tension is lessened to allow the prosthesis to self-expand. In a tethered and expanded state in which the prosthesis has self-expanded and is connected to the spindle by the cord, the lateral control feature directs the spindle to a prescribed location relative to the prosthesis appropriate for a functional evaluation of the prosthesis. In some embodiments, the spindle is directed to a center of the prosthesis; in other embodiments, the spindle is held at a commissure of the prosthesis. The lateral control features of the present disclosure assume numerous forms.
