  • Patent number: 12011349
    Abstract: A transcatheter valve prosthesis includes a stent and a prosthetic valve. The stent includes an inflow portion, an outflow portion, and a transition portion extending between the inflow portion and the outflow portion. The transition portion includes a plurality of axial frame members, and three of the plurality of the axial frame members are commissure posts. At least two of the plurality of the axial frame members are commissure posts having a first end connected to a crown of the inflow portion and an unattached second end disposed within the outflow portion such that a pair of struts of the outflow portion intersect each commissure post at a mid-portion thereof. The prosthetic valve is configured to substantially block blood flow in one direction to regulate blood flow through a central lumen of the stent.

  • Patent number: 11771554
    Abstract: A transcatheter valve prosthesis includes a stent and a prosthetic valve disposed within the stent. The stent is balloon expandable and includes an inflow portion, an outflow portion, and a transition portion extending between the inflow portion and the outflow portion. A diameter of an inflow end of the transcatheter valve prosthesis is greater than a diameter of an outflow end of the transcatheter valve prosthesis. The transcatheter valve prosthesis has a tapered profile along an entire height thereof when in the stent is in the expanded configuration. The inflow end of the transcatheter valve prosthesis is configured to sit within and contact an aortic annulus of the native aortic valve and the outflow end of the transcatheter valve prosthesis being configured to float within an ascending aorta without contacting the ascending aorta due to the tapered profile of the transcatheter valve prosthesis.

  • Publication number: 20220160424
    Abstract: Devices, systems, and methods for the selective positioning of an intravascular neuromodulation device are disclosed herein. Such systems can include, for example, an elongated shaft and a therapeutic assembly carried by a distal portion of the elongated shaft. The therapeutic assembly is configured for delivery within a blood vessel. The therapeutic assembly can include a pre-formed shape and can be transformable between a substantially straight delivery configuration: and a treatment configuration having the pre-formed helical shape to position the therapeutic assembly in stable contact with a wall of the body vessel. The therapeutic assembly can also include a mechanical decoupler operably connected to the therapeutic assembly that is configured to absorb at least a portion of a force exerted on the therapeutic assembly by the shaft so that the therapeutic assembly maintains a generally stationary position relative to the target site.

  • Patent number: 10512504
    Abstract: Catheter apparatuses, systems, and methods for achieving renal neuromodulation by intravascular access are disclosed herein. One aspect of the present technology, for example, is directed to a treatment device having a multi-electrode array configured to be delivered to a renal blood vessel. The array is selectively transformable between a delivery or low-profile state (e.g., a generally straight shape) and a deployed state (e.g., a radially expanded, generally spiral/helical shape). The multi-electrode array is sized and shaped so that the electrodes or energy delivery elements contact an interior wall of the renal blood vessel when the array is in the deployed (e.g., spiral/helical) state. The electrodes or energy delivery elements are configured for direct and/or indirect application of thermal and/or electrical energy to heat or otherwise electrically modulate neural fibers that contribute to renal function.

  • Patent number: 10342612
    Abstract: Catheter apparatuses, systems, and methods for achieving renal neuromodulation by intravascular access are disclosed herein. One aspect of the present application, for example, is directed to apparatuses, systems, and methods that incorporate a catheter treatment device comprising an elongated shaft. The elongated shaft is sized and configured to deliver an energy delivery element to a renal artery via an intravascular path. Thermal or electrical renal neuromodulation may be achieved via direct and/or via indirect application of thermal and/or electrical energy to heat or cool, or otherwise electrically modulate, neural fibers that contribute to renal function, or of vascular structures that feed or perfuse the neural fibers.

  • Patent number: 10226367
    Abstract: Methods and apparatus are disclosed for filling a therapeutic substance or drug within a hollow wire that forms a stent. The stent is placed within a chamber housing a fluid drug formulation. During filling, the chamber is maintained at or near the vapor-liquid equilibrium of the solvent of the fluid drug formulation. To fill the stent, at least a portion of the stent is placed into contact with the fluid drug formulation until a lumenal space defined by the hollow wire is at least partially filled with the fluid drug formulation via capillary action. After filling is complete, the stent is retracted such that the stent is no longer in contact with the fluid drug formulation. The solvent vapor pressure within the chamber is reduced to evaporate a solvent of the fluid drug formulation. A wicking means may control transfer of the fluid drug formulation into the stent.
