  • Publication number: 20180104049
    Abstract: An assembly includes an expandable prosthetic heart valve, a catheter shaft, and a stabilization device. The expandable prosthetic heart valve has a valve body and a plurality of leaflets coupled to the valve body. The catheter shaft has a proximal end portion and a distal end portion. The prosthetic heart valve is coupled to the distal end portion of the catheter shaft. The stabilization device is coupled to the catheter shaft adjacent the prosthetic heart valve and is movable between a contracted configuration and an expanded configuration. In the expanded configuration, the stabilization device is configured to contact surrounding tissue adjacent a site of implantation to stabilize the catheter shaft relative to the site of implantation while the prosthetic heart valve is radially expanded from a radially-compressed state to a radially-expanded state at the site of implantation.

  • Patent number: 9848985
    Abstract: A system for delivering and deploying a self-expandable heart valve to a site of implantation such as the aortic annulus includes a deployment mechanism that engages the valve and regulates the rate of expansion of both the proximal and distal ends thereof. The heart valve may be a rolled-type valve and the deployment mechanism may include a plurality of distal fingers and a plurality of proximal fingers that engage the outer layer of the heart valve. Controlled radial movement of the fingers regulates the unwinding of the rolled heart valve. The deployment mechanism may include an umbrella structure that forces the rolled valve outward into its fully expanded configuration. Alternatively, a gear shaft that engages one or more gear tracks on the valve may be utilized to regulate expansion of the valve.

  • Publication number: 20170281345
    Abstract: A method of implanting a prosthetic heart valve includes advancing the prosthetic heart valve in a radially-contracted configuration into an annulus of a native aortic valve. The prosthetic heart valve includes a self-expanding body and a plurality of leaflets fastened to the body. The body of the prosthetic heart valve is formed with an annulus anchoring section, a sinus section, and an outflow section. During implantation, the prosthetic heart valve is allowed to self-expand such that the annulus anchoring section contacts the annulus of the native aortic valve and the outflow section contacts a native ascending aorta. The outflow section is less rigid than the annulus anchoring section for conforming to the native ascending aorta. The outflow section flares outwardly from the sinus section. The sinus section preferably includes three sinus apertures.

  • Publication number: 20170128203
    Abstract: A mitral valve prosthesis can be delivered within the native mitral annulus. The valve prosthesis has a valve component on which prosthetic valve leaflets are attached, and a lower support which anatomically and dynamically conforms to a native mitral valve annulus and which is flexibly attached to the valve component. The valve prosthesis can be delivered to the native mitral valve annulus in a collapsed configuration in which the valve component and anchoring element are serially rather than concentrically positioned to one another, thereby minimizing the diameter of the valve prosthesis during delivery. The devices and methods described are useful for treatment of various mitral valve disorders which result in, for example, mitral regurgitation.

  • Publication number: 20170119561
    Abstract: A crimper device can facilitate sheathing of a stent frame for vascular delivery. The device can include first and second components that rotate relative to each other to drive radial movement of one or more compression members of the device. The one or more compression members can direct and balance a compressive force within an aperture of the device. In use, the stent frame can be positioned within the aperture and be compacted by actuation of the compression members.

  • Patent number: 9634399
    Abstract: An antenna system can impart orbital angular momentum (OAM) to an incident electromagnetic (EM) signal from a feed antenna. The antenna system can include a partial OAM antenna with a reflective surface that has only part of a full OAM shaped surface. The antenna system can thus reflect the incident EM signal as a partial OAM beam rather than a full OAM beam.

  • Patent number: 9539091
    Abstract: A method for delivering and implanting a prosthetic heart valve in a native aortic valve includes collapsing a prosthetic heart valve to a contracted configuration while the prosthetic heart valve is coupled to a mechanical deployment mechanism. A catheter shaft is advanced over a guidewire and through a femoral artery with the deployment mechanism and prosthetic heart valve disposed along a distal end portion thereof. The prosthetic heart valve is permitted to self-expand to an initial expanded configuration. The deployment mechanism is actuated from an operating handle to expand the prosthetic heart valve from the initial expanded configuration to a final expanded configuration. The prosthetic heart valve is locked in the final expanded configuration via a mechanical locking device located on the prosthetic heart valve.

  • Patent number: 9452046
    Abstract: A method for replacing a diseased aortic valve includes selecting a prosthetic heart valve based on a measurement of a patient's aortic annulus, the prosthetic heart valve stored in a storage container while in an expanded configuration. The preservative solution is drained from the storage container and the prosthetic heart valve is removed. The prosthetic heart valve is compressed to a contracted configuration and advanced through a patient's vasculature along a distal end portion of a catheter system. The prosthetic heart valve is positioned within the diseased aortic valve and re-expanded to an initial expanded configuration. A deployment mechanism is actuated via an operating handle to further expand the prosthetic heart valve into secure engagement with surrounding tissue until lockout features on the prosthetic heart valve secure the prosthetic heart valve in a final expanded configuration.

  • Patent number: 9350084
    Abstract: Electromagnetic (EM) feeds can illuminate a standard primary reflective antenna with a plurality of feed beams each having a different orbital angular momentum (OAM) or polarization. The reflective antenna, which can be a non-OAM antenna, can reflect the feed beams and thereby produce a composite OAM transmission comprising each of the feed beams. A non-OAM primary antenna can thus transmit a plurality of OAM feed beams as a composite OAM transmission.
