    2. High-resolution image-guided WEB aneurysm embolization by high-frequency optical coherence tomography

      High-resolution image-guided WEB aneurysm embolization by high-frequency optical coherence tomography
      Background High-frequency optical coherence tomography (HF-OCT) is an intra-vascular imaging technique capable of assessing device-vessel interactions at spatial resolution approaching 10m. We tested the hypothesis that adequately deployed Woven EndoBridge (WEB) devices as visualized by HF-OCT lead to higher aneurysm occlusion rates. Methods In a leporine model, elastase-induced aneurysms (n=24) were treated with the WEB device. HF-OCT and digital subtraction angiography (DSA) were performed following WEB deployment and repeated ...

    3. A neurovascular high-frequency optical coherence tomography system enables in situ cerebrovascular volumetric microscopy

      A neurovascular high-frequency optical coherence tomography system enables in situ cerebrovascular volumetric microscopy
      Intravascular imaging has emerged as a valuable tool for the treatment of coronary and peripheral artery disease; however, no solution is available for safe and reliable use in the tortuous vascular anatomy of the brain. Endovascular treatment of stroke is delivered under image guidance with insufficient resolution to adequately assess underlying arterial pathology and therapeutic devices. High-resolution imaging, enabling surgeons to visualize cerebral arteries' microstructure and micron-level features of neurovascular ...

    4. Longitudinal Monitoring of Flow-Diverting Stent Tissue Coverage After Implant in a Bifurcation Model Using Neurovascular High-Frequency Optical Coherence Tomography

      Longitudinal Monitoring of Flow-Diverting Stent Tissue Coverage After Implant in a Bifurcation Model Using Neurovascular High-Frequency Optical Coherence Tomography
      BACKGROUND Tissue growth over covered branches is a leading cause of delayed thrombotic complications after flow-diverter stenting (FDS). Due to insufficient resolution, no imaging modality is clinically available to monitor this phenomenon. OBJECTIVE To evaluate high-frequency optical coherence tomography (HF-OCT), a novel intravascular imaging modality designed for the cerebrovascular anatomy with a resolution approaching 10 microns, to monitor tissue growth over FDS in an arterial bifurcation model. METHODS FDS were ...

    5. Acute Thrombus Burden on Coated Flow Diverters Assessed by High Frequency Optical Coherence Tomography

      Acute Thrombus Burden on Coated Flow Diverters Assessed by High Frequency Optical Coherence Tomography
      Purpose The implantation of flow diverters requires administration of dual anti-platelet therapy, posing the potential for complications. The p48MW HPC (phenox, Bochm, Germany) hydrophilic-coated flow diverting stent is designed to be anti-thrombotic, thus opening the potential for single anti-platelet therapy. We deploy a novel intravascular high-resolution imaging technique, high-frequency optical coherence tomography (HF-OCT), to study in an animal model the acute thrombus formation on coated p48MW devices versus uncoated control ...

    6. Imaging system includes imaging probe and delivery devices

      Imaging system includes imaging probe and delivery devices
      An imaging system is provided comprising an imaging probe and at least one delivery device. The imaging probe comprises an elongate shaft, a rotatable optical core and an optical assembly. The elongate shaft comprises a proximal end, a distal portion, and a lumen extending between the proximal end and the distal portion. The rotatable optical core is positioned within the lumen of the elongate shaft and comprises a proximal end ...

      Use of optical coherence tomography deemed feasible after first-in-human analysis
      Results of the first-in-human analysis of acute interactions and healing process after flow diverter implantation using optical coherence tomography (OCT) imaging was presented by Boris Pab n and Juan Mejia as members of Angioteam, Angiodinamia, Clinica Del Norte, Medelln, Colombia, at the 15 th Congress of the World Federation of Interventional and Therapeutic Neuroradiology (WFITN; 2124 October 2019, Naples, Italy). Having evaluated three patients at the time of presentation, Pabn ...

    9. High frequency optical coherence tomography assessment of homogenous neck coverage by intrasaccular devices predicts successful aneurysm occlusion

      High frequency optical coherence tomography assessment of homogenous neck coverage by intrasaccular devices predicts successful aneurysm occlusion
      Background High frequency optical coherence tomography (HF-OCT) is a novel intravascular imaging technology developed for use in the cerebral vasculature. We hypothesize that HF-OCT characterization of intrasaccular device neck coverage can prognosticate exclusion of the aneurysm from the circulation. Methods Bifurcation and sidewall aneurysms were made in six dogs. Seven aneurysms were treated with next generation intrasaccular devices (NGID) and four with traditional platinum coils. HF-OCT was performed to interrogate ...

    10. IMAGE-GUIDED ENDOVASCULAR NEUROSURGERY: HIGH-RESOLUTION CEREBROVASCULAR IMAGING

      IMAGE-GUIDED ENDOVASCULAR NEUROSURGERY: HIGH-RESOLUTION CEREBROVASCULAR IMAGING
      The goal of this program is the development of a high-resolution, neuroendovascular imaging platform that provides detailed information on intravascular devices used to treat brain aneurysms. Miniaturization of the design features of neurovascular stents and flow-diverters (FD) with braided wires of 20 m and laser cut features of 10 m, has enabled an explosion of technology available for endovascular treatment of stroke. Despite these advances, however, several questions remain unanswered ...
