  • Patent number: 10463509
    Abstract: A stent includes a central portion of helically wound undulations formed of struts, cylindrical end portions, and transition zones between the helical portion and the cylindrical portions. According to a first aspect of the invention, the torsional flexibility of the stent is maximized by having bridges connecting adjacent windings be interrupted by the maximum possible number of undulations. In one embodiment, each winding includes nineteen undulations around the circumference; bridges are provided every five undulations. According to a second aspect of the invention, uniform opening of the transition zone is achieved by altering the width, and thereby the flexibility, of a series of struts in accordance with their lengths. Specifically, the long transition zone struts are made wider.

  • Patent number: 10159527
    Abstract: A method for delivering RF energy to living tissue includes the steps of extending a guidewire to a tissue treatment site in a body. A controllable stiffness catheter is provided with a stiffness device having non-metallic properties and a temperature-changing device. The stiffness device is in a stiff state below a given temperature and in a soft state above the given temperature. While supplying power to the temperature-changing device, the catheter is threaded along the guidewire up to the treatment site in the soft state. Power is removed from the temperature-changing device to alter the non-metallic properties of the stiffness device and directly result in a change of the stiffness device to the stiff state without straightening the catheter. The RF energy supply device is physically contacted with the treatment site and RF energy is delivered to the treatment site from the RF energy supply device.

  • Publication number: 20180289925
    Abstract: A catheter comprises a heater control supplying power, a handle, a base catheter with lumen and comprising a proximal section and a distal segment, and a variable stiffness element. The element comprises a heater connected to the heater control, coiled at least at the distal segment, and comprising a shaft portion of a first metallic conductive material and a heater portion of a second metallic conductive material. A jacket is disposed about the heater portion. A variable flex sub-assembly between the catheter and jacket comprises a non-conducting braid and a binding material. Without power, the binding material is stiffened. Responsive to heating of the binding material, the binding material softens to increase flexibility of the variable flex sub-assembly at least at the distal segment. Responsive to removing power, the binding material cools and stiffens to decrease flexibility of the variable flex sub-assembly at least at the distal segment.
