  • Patent number: 11883282
    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.

  • Publication number: 20230233326
    Abstract: A method comprises inserting a needle into a ventricle of a heart. The needle is configured to deliver a first anchoring element, a second anchoring element, and a tethering suture to the ventricle. The tethering suture is tethered between the first anchoring element and the second anchoring element. The method further comprises penetrating a first leaflet of a heart valve with the needle, penetrating a second leaflet of the heart valve with the needle, deploying the first anchoring element at a distal side of the second leaflet, retracting the needle from the first leaflet and the second leaflet, deploying the second anchoring element at a proximal side of the first leaflet, cinching the tethering suture to cause a desired amount of valve coaptation, and locking the tethering suture.

  • Publication number: 20230072121
    Abstract: A quick-connect heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The heart valve includes a substantially non-expandable, non-compressible prosthetic valve and a plastically-expandable frame, thereby enabling attachment to the annulus without sutures. A small number of guide sutures may be provided for aortic valve orientation. The prosthetic valve may be a commercially available valve with a sewing ring with the frame attached thereto. The frame may expand from a conical deployment shape to a conical expanded shape, and may include web-like struts connected between axially-extending posts. A system and method for deployment includes an integrated handle shaft and balloon catheter. A valve holder is stored with the heart valve and the handle shaft easily attaches thereto to improve valve preparation steps.

  • Patent number: 11590550
    Abstract: An apparatus for crimping a radially expandable stent includes a pressure vessel, shaping balloon, and mandrel. The mandrel is configured to slidingly receive a stent thereon, and to be slidingly advanced into the pressure vessel. The shaping balloon is inflated to radially compress the stent onto the form of the mandrel; such compression need not be uniform. Pressurization of the shaping balloon facilitates the expansion of the balloon to achieve compression of the stent, with depressurization of the shaping balloon causing the balloon to return to an unexpanded state.

  • Patent number: 11517435
    Abstract: A prosthetic cardiac valve assembly and method of implanting the same is disclosed. In certain disclosed embodiments, the prosthetic valve assembly is an annuloplasty ring with an attached artificial valve. The prosthetic valve assembly can be secured to native heart tissue by suturing or other suitable method of the annuloplasty ring to the native heart tissue. The prosthetic valve leaflets of the prosthetic valve can also be anchored to the native heart tissue to prevent prolapse. In certain embodiments, the prosthetic valve leaflets are anchored to the native papillary muscles. In still other embodiments, the prosthetic valve assembly contains exactly the number of prosthetic valve leaflets as are in the native valve that the prosthetic valve assembly is configured to replace. With the prosthetic valve assembly properly positioned, it will replace the function of the native valve.

  • Publication number: 20220151759
    Abstract: A packaging assembly for storing a bioprosthetic heart valve is disclosed. The packaging assembly can include a sub-assembly comprising a valve holder configured to hold the bioprosthetic heart valve, and a clip configured to receive a shaft of the valve holder. The clip can comprise a body having an outer periphery and opposing inner edges. The opposing inner edges can define a slot in the body for receiving the shaft of the valve holder. The slot can be open at a first end of the body and extend, along a longitudinal axis of the body, from the first end to a docking aperture. The clip can further comprise a compliance feature in an interference-fit area of the slot adjacent to the docking aperture. The compliance feature can comprise a cutout adjacent to each of the opposing inner edges such that each of the opposing inner edges defines a beam within the interference-fit area.

  • Publication number: 20210353408
    Abstract: A hybrid heart valve prosthesis that can be quickly and easily implanted during a surgical procedure is provided. The hybrid heart valve includes a substantially non-expandable, non-compressible prosthetic valve member having a peripheral sealing ring and an expandable stent frame projecting from an inflow end, thereby enabling attachment to the annulus without sutures. The stent frame may be plastically-expandable and may have a thin fabric layer covering its entirety as well as secondary sealing structures around its periphery to prevent paravalvular leaking. Other sealing solutions include interactive steps at the time of valve implant to establish seals around the stent and especially between the stent and the sealing ring of the valve member.

  • Patent number: 10702680
    Abstract: An inflation system having two pressure vessels integrated into a balloon catheter. A pressurized chamber and a vacuum chamber are integrally attached to proximal end of the balloon catheter and activated by a common valve or switch. Pressure or vacuum is selectively transmitted to the balloon depending on the valve/switch position. The working fluid may be air, or a combination of air and saline with an intermediate piston/cylinder assembly. The balloon catheter may be a part of a heart valve delivery system with a balloon-expandable heart valve crimped onto the balloon.
