  • High speed chronic total occlusion crossing devices
    Patent number: 11931061
    Abstract: An occlusion crossing device includes an outer shaft, an inner shaft, an optical fiber, and a handle attached to the inner shaft and the outer shaft. The inner shaft extends within the outer shaft. The inner shaft includes a drill tip at a distal end thereof. The optical fiber extends within the inner shaft substantially along a central axis of the inner shaft. The distal tip of the optical fiber is attached to the drill tip. The handle is configured to rotate the inner shaft and drill tip at speeds of greater than 500 rpm.

  • METHODS, SYSTEMS AND APPARATUSES FOR DISPLAYING REAL-TIME CATHETER POSITION
    Publication number: 20190313941
    Abstract: A system for tracking and displaying a real-time catheter position overlaying a fluoroscopic image includes a catheter having an optical coherence tomography (OCT) sensor thereon, a displacement sensor configured to identify displacement of the catheter, a controller, and a display. The controller is configured to receive a fluoroscopic image of the distal end of the catheter at a first position and determine a displacement of the catheter from the first position to a second position using the displacement sensor. The display is configured to display the distal end of catheter at the second position as an overlay on the fluoroscopic image.
