    2. Randomized Comparison Between Everolimus-Eluting Bioresorbable Scaffold and Metallic Stent Multimodality Imaging Through 3 Years

      Randomized Comparison Between Everolimus-Eluting Bioresorbable Scaffold and Metallic Stent Multimodality Imaging Through 3 Years
      Objectives The aim of this study was to investigate the vascular responses and fates of the scaffold after bioresorbable vascular scaffold (BVS) implantation using multimodality imaging. Background Serial comprehensive image assessments after BVS implantation in the context of a randomized trial have not yet been reported. Methods In the ABSORB Japan trial, 400 patients were randomized to a BVS (n = 266) or a cobalt-chromium everolimus-eluting stent (n = 134). Through 3 ...

    3. Guidewire detection systems, methods, and apparatuses

      Guidewire detection systems, methods, and apparatuses
      In part, the disclosure relates to methods of guidewire detection in intravascular data sets such as scan lines, frames, images and combinations thereof. Methods of generating one or more indicia of a guidewire in a representation of blood vessel are also features of the disclosure. A carpet view is generated in one embodiment and regions of relatively higher contrast are detected as candidate guidewire regions. In one embodiment, the disclosure ...

    4. Detection of and validation of shadows in intravascular images

      Detection of and validation of shadows in intravascular images
      In part, the disclosure relates to shadow detection and shadow validation relative to data sets obtained from an intravascular imaging data collection session. The methods can use locally adaptive thresholds and scan line level analysis relative to candidate shadow regions to determine a set of candidate shadows for validation or rejection. In one embodiment, the shadows are stent strut shadows, guidewire shadows, side branch shadows or other shadows.

    5. In-Stent Restenosis Lesion Morphology Related to Repeat Stenting Underexpansion as Evaluated by Optical Coherence Tomography

      In-Stent Restenosis Lesion Morphology Related to Repeat Stenting Underexpansion as Evaluated by Optical Coherence Tomography
      Aims: To use optical coherence tomography (OCT) to predict newly implanted stent expansion for treatment of in-stent restenosis (ISR). Methods and results: With OCT-guidance, 143 ISR lesions were treated with a new stent. Stent underexpansion was defined as minimum stent area (MSA) 4.5mm 2 and MSA/average of reference lumen area 70%. New stent underexpansion was found in 33 lesions (23%), had a smaller old stent MSA (4.13 ...

    6. Intravascular imaging user interface systems and methods

      Intravascular imaging user interface systems and methods
      In part, the disclosure relates to intravascular data collections and generation of representations thereof include one or more view of regions associated with side branches or arteries such as a carina or bifurcation. In one embodiment, accessing a set of intravascular data stored in machine readable memory; performing side branch detection with regard to the intravascular data to identify one or more side branches; and identifying a plurality of frames ...

    7. Intravascular imaging system interfaces and stent detection methods

      Intravascular imaging system interfaces and stent detection methods
      The disclosure relates, in part, to computer-based visualization of stent position within a blood vessel. A stent can be visualized using intravascular data and subsequently displayed as stent struts or portions of a stent as a part of a one or more graphic user interface(s) (GUI). In one embodiment, the method includes steps to distinguish stented region(s) from background noise using an amalgamation of angular stent strut information ...

    8. First Human Evaluation of Endothelial Healing after a Pipeline Flex Embolization Device with Shield Technology Implanted in Posterior Circulation Using Optical Coherence Tomography

      First Human Evaluation of Endothelial Healing after a Pipeline Flex Embolization Device with Shield Technology Implanted in Posterior Circulation Using Optical Coherence Tomography
      A 64-year-old female presented with an incidentally-discovered right posterior inferior cerebral artery (PICA) aneurysm, initially treated in 2015 by simple coiling. Follow-up demonstrated significant coil compaction that required retreatment. Retreatment was done uneventfully using a Pipeline embolization device (PED) shield deployed starting from the basilar artery and ending at the V4 segment of the vertebral artery. Eight-weeks post-deployment, a follow-up digital subtraction imaging (DSA) and intravascular imaging with optical coherence ...

    9. Friction torque limiter for an imaging catheter

      Friction torque limiter for an imaging catheter
      The invention provides a frictional torque limiter assembly for an imaging core spinning in a patient's body. The torque limiter assembly torsionally isolates the imaging core from a motor that spins the imaging core. An interference fit between a slitted drive tube and a spacer tube acts as a clutch that allows a spinning imaging probe to slow or stop relative to the motor until the motor is stopped ...

    10. Intravascular Measurement and Data Collection Systems, Apparatus and Methods

      Intravascular Measurement and Data Collection Systems, Apparatus and Methods
      A method and apparatus for determining properties of a tissue or tissues imaged by optical coherence tomography (OCT). In one embodiment the backscatter and attenuation of the OCT optical beam is measured and based on these measurements and indicium such as color is assigned for each portion of the image corresponding to the specific value of the backscatter and attenuation for that portion. The image is then displayed with the ...
