    2. 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 ...

      Atherectomy Catheters And Occlusion Crossing Devices
      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 at a hinge point that is offset (e.g., located on a side of the elongate body near the distal end of the elongate body) and a rotatable cutter near an imaging ...

    1. These acute results from the VISION study have exceeded even my high expectations going into the trial...Never before have we been able to see the arterial wall during atherectomy, nor have I seen these types of results, with this much control over the procedure outcomes and so little adjunctive therapy required to achieve the desired angiographic results, with only 4% of lesions treated receiving placement of a stent. Based on the data we have seen to date, I believe we continue to be on track to meet or exceed our primary safety endpoint once all six-month follow-up data becomes available.

    3. With its smaller profile and longer length, Ocelot | PIXL is designed to bring all the benefits of Ocelot to help physicians treat more patients with smaller arteries...Because Ocelot | PIXL, like the original Ocelot catheter, uses real-time intravascular imaging via optical coherence tomography (OCT), I’m confident more legs will be saved, and more patients will walk home happy.

    4. It has taken my entire career to get to this moment...Incorporating intravascular OCT into therapeutic devices has been the biggest priority here at Avinger. We have amazing investors who have allowed us to demonstrate how revolutionary Avinger can be. I’m so proud of our employees, all the physicians and hospitals around the world that helped us bring this amazing technology to the patients in the US.

  4. Quotes about John B. Simpson

    1. Avinger's Dr. John B. Simpson has invented a technology that enables Austin Heart's team of interventional cardiologists to treat PAD patients with more precision than ever before possible...The trial is hoping to help patients regain mobility and improve quality of life, and in the process many patients might be spared unnecessary amputations. Austin Heart is committed to saving the legs of our PAD patients so they can return to a healthy life.
