  • Patent number: 8057396
    Abstract: Devices for assessing the size, shape, and topography of vessel lumens and hollow portions of organs are described. The devices are particularly adapted for determining the size, shape, topography, and compliance of the native heart valves to facilitate the later implantation of a prosthetic heart valve. The devices are typically catheter-based having an assessment mechanism fixed to a distal end of the catheter. The assessment mechanism generally includes an expandable member, such as a balloon. The assessment mechanism may also include an imaging member, a physical assessment member, an electronic mapping construction, an alignment mechanism, a valvuloplasty balloon, or any combination thereof.

  • Publication number: 20100256752
    Abstract: The implantable heart valve can have an inverted configuration and can include a support structure and at least two valve leaflets. Preferably, when the valve is placed in proximity with an aortic valve implantation site of a subject and engaged with the implantation site, the valve leaflets are configured to deflect towards the aortic wall into a first position for resisting the flow of blood towards the left ventricle and configured to deflect away from a aortic wall into a second position for allowing the flow of blood from a left ventricle, with the support structure configured to remain static during leaflet deflection.

  • Publication number: 20090210052
    Abstract: Described herein are systems and methods for operation of a prosthetic valve support structure (32) having additional reinforcement coupled with panels (36). Multiple support members (620) are distributed across the inner surface of the valve support structure (32) at regular intervals. Each support member (620) can include a looped portion (621) to act as a hinge (52). Each looped portion (621) is in a location coincidental with the interlace between adjacent panels (36).

  • Publication number: 20090182416
    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: 20070255398
    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.

  • Publication number: 20070168020
    Abstract: A bifurcated stent includes a first stent section and a second stent section. The first stent section is balloon expandable, has an unexpanded configuration, an expanded configuration, and a tubular wall defining a secondary opening. The secondary stent section is self-expanding and an end of the secondary stent section is engaged to a portion of the tubular wall of the primary stent section defining the secondary opening. The secondary stent section has an unexpanded configuration with a first length and an expanded configuration with a second length where the first length is less than the second length. The secondary stent section is expanded to the expanded configuration after the primary stent section is expanded to the expanded configuration. The secondary stent section forms a portion of the tubular wall of the primary stent section in the unexpanded configuration.
