  • Publication number: 20220118225
    Abstract: The present disclosure relates to devices and methods for accessing a targeted vessel, such as a coronary artery, near the aortic root. A catheter device includes a proximal section, an intermediate section, and a distal section. The intermediate section includes a more proximal section (a proximal-intermediate section) and a more distal section (a distal-intermediate section). The proximal-intermediate section is microfabricated to enable preferred bending along a single plane. The distal-intermediate section is more rigid than the proximal-intermediate section and the distal section. In use, the proximal-intermediate section abuts against the aortic wall and bends to allow the distal-intermediate section to extend across the aortic root toward a targeted vessel on the opposite side of the aorta.

  • Patent number: 11207502
    Abstract: The present disclosure relates to guidewire devices having shapeable tips and effective torquability. A guidewire device includes a core having a proximal section and a tapered distal section. A tube structure is coupled to the core such that the tapered distal section extends into the tube structure. The tube structure includes a plurality of bypass cuts formed tangentially within the tube structure to increase the flexibility of the tube structure and to reduce the tendency of resilient forces from the tube structure to disrupt a shaped distal tip of the guidewire device.

  • Publication number: 20210346656
    Abstract: Disclosed is a guidewire configured to provide high torsional stiffness without detrimentally increasing bending stiffness. Such a device provides a high ratio of torsional stiffness to bending stiffness. The guidewire device includes a core with a proximal section and a distal section. The distal section of the core is coupled to a microfabricated outer tube such that the distal section of the core passes into and is encompassed by the outer tube.

  • Publication number: 20210228845
    Abstract: Disclosed is a guidewire having a core wire and an outer tube within which the distal section of the core is inserted. The outer diameter of the tube is greater than the outer diameter of the proximal section of the core wire. The guidewire also includes a proximal coil and a distal, radiopaque coil each disposed over the distal section of the core. A bushing coil is disposed over the proximal coil and distal coil. The proximal coil, distal coil, and bushing coil aid in filling the annular space between the core and the tube and thereby centering and aligning the core and tube.

  • Publication number: 20210178128
    Abstract: The present disclosure relates to guidewire devices having shapeable tips and effective torquability. A guidewire device includes a core having a proximal section and a tapered distal section. A tube structure is coupled to the core such that the tapered distal section of the core extends into and distally beyond the tube structure. The portion of the core extending distally beyond the tube forms a shapeable tip. One or more coils also extend distally beyond the tube. The tip is configured to reduce the tendency of resilient forces from the tube structure to disrupt a customized shape of the tip.

  • Publication number: 20210008351
    Abstract: The present disclosure relates to vascular devices such as guidewires and microcatheters having integrated coil sections for optimizing torquability, flexibility, and ability to shape and maintain the distal tip. A guidewire device includes a core and a tube structure coupled to the core such that at least a portion of the core passes into the tube structure. A distal section of the tube structure includes a spiral cut arrangement that configures the distal section as an integral coil integrally incorporated as part of the tube structure. The integrated coil configuration increases the flexibility of the tube structure to reduce the tendency of resilient forces from the tube structure to disrupt a shaped distal tip of the guidewire device.

  • Publication number: 20200345975
    Abstract: Disclosed are intravascular devices having enhanced one-beam cut patterns. An elongated member includes a plurality of fenestrations that define a plurality of axially extending beams interspersed between a plurality of circumferentially extending rings. The beams are formed using a dual-pass cutting method in which a blade makes two, rotationally offset cutting passes at a given longitudinal location of the elongated member. The resulting beam has enhanced structure that avoids overly sharp edges and minimizes structural weak points.

  • Publication number: 20200222672
    Abstract: The present disclosure relates to guidewire devices with an outer tube and a core. The distal section of the core extends into and is surrounded by the outer tube. One or more centering mechanisms are also disposed within the outer tube and are arranged to fill a portion of the annular space between the core and the inner surface of the tube. The one or more centering mechanisms thereby assist in keeping the distal section of the core axially aligned within the tube, which enables effective control of the device and minimizes undesirable whip movements of the guidewire.
