  • Patent number: 9669188
    Abstract: A noncircular inner lumen guiding catheter with assisted variable support has an inner wall defining a noncircular cross-sectional shaped lumen for use in delivery of multiple microcatheters or other devices for treatment of neurovascular defects, such as for treatment of aneurysms. The noncircular inner lumen guiding catheter with assisted variable support includes torque transmittal guidance walls that are flexible linearly but not circumferentially, and that are neither collapsible nor kinkable. The noncircular shaped cross-section of the inner lumen may extend along the entire length of the catheter or a portion thereof, including distal or proximal.

  • Publication number: 20150174378
    Abstract: A medical device formed of a coil with repeating loops, each loop forming a polygon and each successive loop being slightly rotated with respect to its adjacent loops to form a spiral configuration. The polygon in a preferred embodiment is a triangle, and the repeating triangular loop coil can be used as a guidewire in a stent delivering catheter. The guidewire can further include a stiff core wire that is disposed within the triangular loop coil, where the stiff core wire includes tapered sections that reduce the stiffness in the distal direction. The coil can include multiple sections of different loop shapes, including circular, to alter the stiffness of the guidewire to meet the needs of the application.
