  • Publication number: 20190290883
    Abstract: Polymer catheters and guidewires for use in intravascular surgery, and more particularly polymer catheters and guidewires micro-machined with a micro-cutting machine to provide sufficient flexibility to travel through a patient's vasculature while retaining sufficient torquability to transmit torque from a proximal end to the distal end of the catheter or guidewire, and methods of producing the same.

  • Publication number: 20190255290
    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.

  • Publication number: 20180193607
    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: 20180177517
    Abstract: An intravascular device, such as s guidewire device, includes a hollow proximal section and a hollow distal section joined to the proximal section and extending distally from the proximal section to form a continuous lumen extending from a proximal end of the device to a distal end of the device. An inner member extends from the proximal end to the distal end and is joined to the distal end. The inner member is translatable within the lumen in response to applied tension. At least the distal section includes a micro-fabricated cutting pattern that enables deflection of the distal end in response to the application of tension to the inner member.

  • Publication number: 20180071496
    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: 20180015262
    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.

  • Patent number: 8939916
    Abstract: Medical devices for navigation through anatomy, including guidewires, which may have a core wire, a slotted tubular member, or both. Embodiments may have coils, including non-circular cross-section edge-wound marker coils, extended coil tips, and soldered or glued mesial joint coils. Core wires may have a step, ridge, or taper at the joints to the tubular member, and may be flattened at the distal tip. Radiopaque material may be located inside the tubular member, and the distal tip may be heat treated to make it shapeable. Additional tubular members or coils may be used concentrically or in line and may enhance flexibility, provide radiopacity, reduce friction, or reduce material or manufacturing cost. Tubular members may be chamfered or tapered continuously or incrementally. Slots may be arranged in groups, such as groups of three, and may be equal in depth or unequal in depth to provide a steerable or compressible tip.
