摘要： An imaging device includes a hollow flexible shaft having a central longitudinal axis and an imaging window therein. An optical fiber extends within the hollow flexible shaft substantially along the central axis. A distal tip of the optical fiber is attached to the hollow flexible shaft and aligned with the imaging window so as to transfer an optical coherence tomography signal through the imaging window. A handle is attached to the hollow flexible shaft configured rotate the hollow flexible shaft at speeds of greater than 1,000 rpm.

摘要： A drive assembly for driving an imaging catheter has a rotatable fiber and a rotatable drive shaft. The drive assembly includes a fiber optic rotating junction and a motor configured to rotate the rotatable portion of the fiber optic rotating junction. In some embodiments, the drive assembly includes a sensor configured to detect a rotational position of the fiber optic rotating junction and a processor configured to obtain the detected rotational position and stop the motor only when the fiber optic rotating junction is in a predetermined rotational position. In some embodiments, the motor includes a hollow shaft through which at least a portion of the fiber optic rotating junction extends.

摘要： Described herein are atherectomy catheters, systems and methods that include longitudinally displaceable drive shafts that drive actuation of one or more cutters at the distal end of the catheter. The catheters described herein may include one or more imaging sensors for imaging before, during or after cutting tissue. In some variations the imaging sensor may be rotated around the perimeter of the catheter independently of the rotation of the cutter. Also describe herein are imaging catheters that may be used without cutters.

摘要： A stylet for re-entry into a vessel includes an elongate body including a proximal portion, a middle curved portion, a pointed distal end, and a longitudinal axis extending through the proximal portion, the middle curved portion, and the pointed distal end. The proximal portion and the middle curved portion have substantially circular cross-sections. The middle curved portion has a pre-shaped curve along the longitudinal axis configured to match a curve of an occlusion-crossing device. The pointed distal end has an s-curve along the longitudinal axis and a flattened portion along the longitudinal axis, the flattened portion having a substantially oblong cross-section.

摘要： An atherectomy catheter includes an elongate flexible catheter body, an elongate deflectable distal tip coupled to the catheter body at a hinge point, a rotatable cutter near the distal end of the catheter body, and a drive shaft extending within the catheter body and configured to rotate the cutter. The atherectomy catheter further includes an optical fiber extending through the drive shaft substantially on-axis with the catheter body and attached to the cutter. The optical fiber is configured to rotate with the drive shaft. The atherectomy catheter further includes a wedge configured to deflect the distal tip away from the catheter body at the hinge point upon axial movement of the drive shaft.

摘要： Versatile tissue collection devices that can provide reduced crossing profiles, fluid pressure release, and/or easy cleaning or removal. In particular, devices having tissue collection devices with multiple configurations to facilitate navigation through narrow vessel cross-sections while also providing adequate tissue storage capacity. Additionally, the devices may include detachable components that allow easy removal, cleaning, and replacement during a procedure. Furthermore, venting elements and sections may be included to relieve fluid buildup in storage reservoirs.
