  • Publication number: 20240299710
    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.

  • Patent number: 12053595
    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: 20240206880
    Abstract: Devices, methods and systems are provided for occluding an opening within the tissue of a body, such as a left atrial appendage. In one embodiment, a medical device includes an occluder portion and an anchor portion. The occluder portion includes a hub that defines an axis, the occluder portion extending between a proximal end coupled to the hub and a distal end defining an occluder eyelet adjacent thereto. The anchor portion extends between a first end and a second end, the first end coupled to an anchor hub and the second end defining an anchor eyelet adjacent thereto and hingeably coupled to the occluder eyelet. With this arrangement, the anchor hub is moveable along the axis to move the anchor portion between a retracted position and a deployed position upon the occluder portion being in an expanded position.

  • Publication number: 20240198059
    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: 20230082226
    Abstract: Disclosed are guidewire and catheter systems that can be used to facilitate desirable catheter axial response (e.g., pushability) over a guidewire for advancement through patient vasculature. Features of the guidewire and catheter systems enable the catheter to advance over the guidewire within the tortuous paths of a patient's vasculature in response to push forces that do not exceed 50 g.

  • Publication number: 20220280147
    Abstract: The present disclosure relates to interventional devices such as catheters and guidewire devices having micro-fabricated features for providing flexibility while maintaining good torquability. An interventional device includes an elongated member having an arrangement of fenestrations which define a plurality of axially extending beams coupling a plurality of circumferentially extending rings. The fenestrations are arranged so that the resulting beams form a distributed, non-helical and non-linear pattern along the length of the elongated member. The pattern of fenestrations thereby minimizes or eliminates preferred bending axes.

  • Publication number: 20220105312
    Abstract: This disclosure describes microfabricated intravascular devices that are configured for high axial strength while also maintaining effective bending flexibility. A tube member includes a series of circumferentially extending rings connected to one another by a series of axially extending beams. Transverse cuts separate and define the rings. A series of axial cuts are aligned with the beams and extend from the beams partially into the adjoining rings so that the beam length is nested partially within the axial length of the adjoining rings. This increases the functional length of the beams to provide bending flexibility while still sufficient ring structure to provide effective axial stiffness.
