    1. Balloon atherectomy catheters with imaging

      Balloon atherectomy catheters with imaging
      An atherectomy catheter includes an elongate flexible catheter body, a cutter near the distal end of the catheter body, a drive shaft connected to the cutter and extending within the catheter body, an imaging element near the distal end of the catheter body and an imaging shaft connected to the imaging element and extending within the catheter body. The cutter and the imaging element are mechanically isolated, and the drive ...

    2. High speed chronic total occlusion crossing devices

      High speed chronic total occlusion crossing devices
      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 ...

    6. Lower Extremity Revascularization Using Optical Coherence Tomography–Guided Directional Atherectomy: Final Results of the EValuatIon of the PantheriS OptIcal COherence Tomography ImagiNg Atherectomy System for Use in the Peripheral Vasculature (VISION) St

      Lower Extremity Revascularization Using Optical Coherence Tomography–Guided Directional Atherectomy: Final Results of the EValuatIon of the PantheriS OptIcal COherence Tomography ImagiNg Atherectomy System for Use in the Peripheral Vasculature (VISION) St
      Purpose: To evaluate the safety and efficacy of a novel optical coherence tomography (OCT)guided atherectomy catheter in treating patients with symptomatic femoropopliteal disease. Methods: The VISION trial ( ClinicalTrials.gov identifier NCT01937351) was a single-arm, multicenter, global investigational device exemption study enrolling 158 subjects (mean age 67.210.5 years; 87 men) across 20 participating sites. In this cohort, 198 lesions were treated with an average length of 5340 mm ...

    7. Atherectomy catheters devices having multi-channel bushings

      Atherectomy catheters devices having multi-channel bushings
      Atherectomy catheters and methods of using them are described herein. In particular, described herein are optical coherence tomography (OCT) catheters that may include a distal tip that can be deflected away from the long axis of the device using a multi-channel bushing. The bushing may include at a hinge point that is offset (e.g., located on a side of the elongate body near the distal end of the elongate ...

    8. Atherectomy catheters with longitudinally displaceable drive shafts

      Atherectomy catheters with longitudinally displaceable drive shafts
      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 ...

    9. Catheter-based off-axis optical coherence tomography imaging system

      Catheter-based off-axis optical coherence tomography imaging system
      Catheter-based Optical Coherence Tomography (OCT) systems utilizing an optical fiber that is positioned off-axis of the central longitudinal axis of the catheter have many advantage over catheter-based OCT systems, particularly those having centrally-positioned optical fibers or fibers that rotate independently of the elongate body of the catheter. An OCT system having an off-axis optical fiber for visualizing the inside of a body lumen may be rotated with the body of ...
