  • GUIDE WIRE TIP HAVING ROUGHENED SURFACE
    Publication number: 20230088749
    Abstract: A guidewire for use in penetrating through complex and stenosed lesions. The distal tip of the guidewire has a roughened surface to increase frictional engagement with calcified and fibrous tissue to increase the penetration of the distal tip and the guidewire into and through the lesion and reduce the likelihood of deflection of the guidewire tip. The average surface roughness of the distal tip is in the range from 1 micron to 200 microns.
    Type: Application
    Filed: August 18, 2022
    Publication date: March 23, 2023
    Applicant: Abbott Cardiovascular Systems Inc.

  • NON-CIRCULAR RADIOPAQUE MARKERS AND METHODS FOR ATTACHING A MARKER TO A SCAFFOLD
    Publication number: 20180133034
    Abstract: A scaffold includes a marker connected to a strut. The marker is retained within the strut by a tongue-and-groove connection. The marker is attached to the strut by a process that includes pressing a non-circular marker into a rectangular hole of the scaffold strut. The strut sidewalls are restrained to produce the tongue and groove connection.
