  • Publication number: 20230285147
    Abstract: A valved conduit including a bioprosthetic aortic heart valve connected to a tubular conduit graft forming an ascending aorta. The conduit graft may attach to the heart valve in a manner that facilitates a redo operation in which the valve is replaced with another valve. A sewing ring may be pre-attached to the inflow end of the graft, and then the valve connected to a delivery holder advanced into the graft and secured to the sewing ring. Dry bioprosthetic valves coupled with conduit grafts sealed with a bioresorbable medium can be stored with the delivery holder.

  • Patent number: 11717404
    Abstract: Valve holders and introducers for delivering a prosthetic heart valve to an implant site are in various embodiments configured to facilitate insertion of prosthetic valves through small incisions or access sites on a patient's body. The valve holders can also be configured to reduce or eliminate the occurrence of suture looping or other damage to the prosthetic valve during implantation. A valve holder according to embodiments of the invention includes features that reduce or eliminate mistakes during implantation of the prosthetic valves, such as a removable activator dial and a removable handle that prevent implantation of the valve prior to proper deployment or adjustment of the holder. An introducer is provided which can facilitate passing of a prosthetic valve between adjacent ribs of a patient. Valve holders and introducers according to the various embodiments can be used in minimally invasive procedures, such as thoracotomy procedures.

  • Publication number: 20230200986
    Abstract: A prosthetic heart valve configured to replace a native heart valve and having a support frame configured to be reshaped into an expanded form in order to receive and/or support an expandable prosthetic heart valve therein is disclosed, together with methods of using same. The prosthetic heart valve may be configured to have a generally rigid and/or expansion-resistant configuration when initially implanted to replace a native valve (or other prosthetic heart valve), but to assume a generally expanded form when subjected to an outward force such as that provided by a dilation balloon or other mechanical expander.

  • Patent number: 11510041
    Abstract: A user of a beacon message distribution service provides a specification for one or more messages to be sent to one or more beacon transmitters to a server. The specification may include at least content for the one or more messages and specification for where the messages are to be sent. The server then determines one or more beacon transmitters to receive the one or more messages based on the specification for where the messages are to be sent. A beacon manager or owner is also identified for the so determined one or more of the beacon transmitters.

  • Publication number: 20220183832
    Abstract: A prosthetic heart valve for implant in a human. The valve includes a wireform with undulating inflow cusps and outflow commissure posts to which flexible leaflets attach and coapt in a flow area. Each leaflet may drape over the top of the wireform in the cusp area, but have tabs that each extend underneath the wireform at the commissure posts to be secured along with a tab of an adjacent leaflet. The prosthetic heart valve may also be a dual-wire wireform, with the leaflets sandwiched therebetween. One wireform may be larger than the other, with the leaflets extending over the smaller wireform. The smaller wireform may have commissures that bend radially outward from the larger wireform to provide structure to which the leaflet tabs attach.

  • Patent number: 11285004
    Abstract: A method for repairing a native valve of a patient during a non-open-heart procedure includes attaching two or more attachment members to the native valve. The method also includes applying a force to the two or more attachment members such that the two or more attachment members cause a cinching effect on at least a portion of the native valve. The method further includes securing the two or more attachment members with one or more anchor members such that the two or more attachment members maintain the cinching effect.

  • Publication number: 20220061992
    Abstract: A heart valve sizer and sizer cover are provided for determining the size of a heart valve annulus. The valve sizer can include a handle, a shaft extending distally from the handle, a sizing element coupled to the distal end of the shaft, the sizing element being movable between a first retracted position and a second expanded position, and a sizer cover. The sizer cover can be formed from a continuous sheet of material configured to surround at least a portion of the sizing element of the heart valve sizer so as to guard against entanglement of the sizing element with structures of a human heart.

  • Publication number: 20220039945
    Abstract: A prosthetic heart valve configured to replace a native heart valve and for post-implant expansion and having a valve-type indicator thereon visible from outside the body post-implant. The indicator communicates information about the valve, such as the size or orifice diameter of the valve, and/or that the valve has the capacity for post-implant expansion. The indicator can be an alphanumeric symbol or other symbol or combination of symbols that represent information about the characteristics of the valve such as the valve size. The capacity for post-implant expansion facilitates a valve-in-valve procedure, where the valve-type indicator conveys information to the surgeon about whether the implanted valve is suitable for the procedure and informs the choice of the secondary valve.

  • Publication number: 20220008199
    Abstract: A prosthetic heart valve configured to replace a native heart valve and having a support frame configured to be reshaped into an expanded form in order to receive and/or support an expandable prosthetic heart valve therein. A dual-wireform support frame including an upper and a lower wireform permits expansion of the valve by one or two valve sizes, for example, with a 2-mm gap between each valve size. The lower wireform has a relatively shallow undulation so that it may stretch apart by a small amount and then prevent further expansion of the valve.
