  • GUIDE WIRE TIP HAVING ROUGHENED SURFACE
    Publication number: 20200222067
    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.

  • RADIOPAQUE INTRALUMINAL STENTS COMPRISING COBALT-BASED ALLOYS WITH PRIMARILY SINGE-PHASE SUPERSATURATED TUNGSTEN CONTENT
    Publication number: 20200038207
    Abstract: Embodiments are directed to radiopaque implantable structures (e.g., stents) formed of cobalt-based alloys that comprise cobalt, chromium, tungsten, and nickel.
