  • Publication number: 20150250588
    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 fingers may be removed prior to inflation of a balloon to fully expand the valve, or the fingers may be repositioned to the inside of the valve for this purpose. 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.

  • Patent number: 9031151
    Abstract: A transmit antenna or antennas can be configured to transmit a composite orbital angular momentum (OAM) radio frequency (RF) beam comprising a plurality of individual OAM RF signals each having a different OAM mode. An array of antennas for receiving and resolving the composite OAM beam into the individual OAM signals can be located entirely within a relatively small sector of a far field pattern of the composite OAM beam. A processing module connected to the antennas of the receive array can resolve the composite OAM beam into its individual OAM signals using angular resolution. The transmit antenna can transmit the individual OAM signals—and thus the composite OAM beam—as full OAM signals or partial-beam OAM signals.

  • Publication number: 20140243958
    Abstract: A method for replacing a native heart valve with a prosthetic heart valve comprises moving a first portion of a prosthetic heart valve towards a second portion of the prosthetic heart valve along a plurality of guide wires, and lock the first portion to the second portion in a final, radially expanded configuration. The prosthetic heart valve is radially contractible and expandable, and in some embodiments, is self-expanding. Embodiments of the method are minimally invasive.

  • Publication number: 20140235361
    Abstract: Torque shafts and other related systems and methods are described herein. The torque shafts are both flexible and capable of transmitting torque. The torque shafts are useful for procedures that require torque and pushability to drive or deploy a device. The flexibility and pushability of the torque shafts enable them to curve along a tortuous path, and the torque transferring capability of the shafts enable them to transmit torque along the shaft.

  • Publication number: 20140194977
    Abstract: Methods and systems for delivering and deploying a prosthetic heart valve include a deployment mechanism coupled to the prosthetic heart valve, the deployment mechanism comprising a longitudinal shaft that when rotated in a first direction, expands the prosthetic heart valve from a contracted state to an expanded state, and optionally, when rotated in a second direction opposite the first direction, re-contracts the prosthetic valve from the expanded state. Embodiments of the deployment mechanism comprise a pinion gear that engages a gear track on the prosthetic heart valve.

  • Patent number: 8740975
    Abstract: A method for delivering and deploying a self-expandable heart valve to a site of implantation such as the aortic annulus. The deployment step may include engaging an outer surface of the heart valve with a plurality of distal fingers and a plurality of proximal fingers. Controlled radial movement of the fingers regulates the expansion of the heart valve. The fingers may be removed prior to inflation of a balloon to fully expand the valve, or the fingers may be repositioned to the inside of the valve for this purpose. The deployment step may include an umbrella structure that forces the 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. A stabilization balloon may be used to axially and radially locate the deployment mechanism relative to the site of implantation.

  • Publication number: 20130023983
    Abstract: Expandable, percutaneously deployable, prosthetic heart valves and systems for minimally invasive replacement of damaged or diseased native aortic valves comprise an expandable, tubular stent body and a unidirectional valve assembly. Embodiments of the stent body comprise an annulus anchoring section, a sinus section, and an outflow section, with the outflow section flared outwardly from the sinus section in an expanded configuration. Embodiments of the stent body are self-expanding, comprising, for example nitinol. The valve assembly disposed within the sinus section of the stent body and sutured thereto. Embodiments of the valve assembly comprise three leaflets, each leaflet comprising a curved outer edge sutured to the sinus section of the stent body, and a coapting free edge. Embodiments of the valve leaflets comprise pericardium, for example, porcine pericardium. Embodiments of the prosthetic heart valve have a contracted configuration dimensioned for percutaneous delivery thereof.

  • Patent number: 7947072
    Abstract: Expandable heart valves for minimally invasive valve replacement surgeries are disclosed. The valves are rolled into a first, contracted configuration for minimally invasive delivery and then unrolled or unfurled at the implantation site. One- and two-piece stents may be used in conjunction with a plurality of flexible leaflet-forming membranes. The one-piece stents may include an annulus anchoring section, a sinus section with the membranes attached over sinus apertures, and a rigid outflow section. The two-piece stent may include a primary stent to provide a tubular base at the annulus, and a secondary stent having the membranes that couples within the primary stent. Lockout tabs to secure the stents in their expanded shapes are provided. Also, alignment structure may be provided to ensure concentric unfurling. Anchoring barbs at the stent edges or in the stent body secure the valve within the annulus. Methods of implantation are also provided.
