  • Patent number: 11969344
    Abstract: Disclosed herein are representative embodiments of methods, apparatus, and systems used to deliver a prosthetic heart valve to a deficient valve. In one embodiment, for instance, a support structure and an expandable prosthetic valve are advanced through the aortic arch of a patient using a delivery system. The support structure is delivered to a position on or adjacent to the surface of the outflow side of the aortic valve (the support structure defining a support-structure interior). The expandable prosthetic valve is delivered into the aortic valve and into the support-structure interior. The expandable prosthetic heart valve is expanded while the expandable prosthetic heart valve is in the support-structure interior and while the support structure is at the position on or adjacent to the surface of the outflow side of the aortic valve, thereby causing one or more native leaflets of the aortic valve to be frictionally secured between the support structure and the expanded prosthetic heart valve.

  • Publication number: 20230255768
    Abstract: Disclosed herein is an expandable sheath that can be used in conjunction with a catheter assembly to introduce a prosthetic device, such as a heart valve, into a patient. The disclosed herein sheath can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some aspects can include a sheath comprising an inner layer comprising a reinforcing layer comprising a plurality of struts that can be encapsulated within a polymer layer comprising a tether portion and an outer layer disposed over the inner layer. The disclosed sheath is configured to locally expand from a predetermined first diameter d1 to an expanded second diameter d2 during application of a radial outward force by passage of a medical device through the sheath.

Such aspects can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some aspects can include a sheath comprising an inner layer comprising a reinforcing layer rolled into a spiral slidable configuration and encapsulated within a polymer layer comprising a tether portion and an outer layer disposed over the inner layer. The disclosed sheath is configured to locally expand from a predetermined first diameter d1 to an expanded second diameter d2 during application of a radial outward force by passage of the medical device through the sheath.

  • Patent number: 11696827
    Abstract: Disclosed herein are representative embodiments of methods, apparatus, and systems used to deliver a prosthetic heart valve assembly. In embodiments, a prosthetic heart valve assembly, including a self-expandable support structure and a self-expanding heart valve, are advanced through the aortic arch of a patient using a delivery system. The support structure, which includes a plurality leaflet retaining arms, is at least partially expanded and positioned on or adjacent to the outflow side of the aortic valve. The prosthetic heart valve is positioned in the aortic valve. The prosthetic heart valve is expanded while it is within an interior of the support structure and while the support structure is positioned on or adjacent to the outflow side of the aortic valve, thereby causing one or more native leaflets of the aortic valve to be frictionally secured between the arms of the support structure and the expanded prosthetic heart valve.

  • Publication number: 20210212816
    Abstract: A valve repair delivery handle includes a housing, an actuation control mechanism, and a clasp control mechanism. The actuation control mechanism includes a knob and an actuation tube. The knob is rotatably coupled to the housing. The actuation tube is coupled to the knob such that rotation of the knob in a first direction moves the actuation tube distally relative to the housing and rotation of the knob in a second direction moves the actuation tube proximally relative to the housing. The clasp control mechanism is coupled to the housing.

  • Patent number: 10722362
    Abstract: An implantable heart valve device has a main body including a first end portion and a second end portion. The main body is configured to be implanted around a native leaflet of a heart valve such that the first end portion is on an atrial side of the leaflet and the second end portion is on a ventricular side of the leaflet, and such that the main body can coapt with an opposing native leaflet during operation of the heart valve. One of the first or second end portions comprises a coupling assembly, and the other of the first or second end portions comprises a coupling member configured to extend through the native leaflet when the heart valve device is implanted in a heart valve. The coupling assembly is configured to releasably engage the coupling member to permit adjustment of the relative positions of the first and second end portions.
