Novel synthetic clot analogs for in-vitro stroke modelling

PLoS ONE, 2022
Purpose The increased demand for training of mechanical thrombectomy in ischemic stroke and development of new recanalization devices urges the creation of new simulation models both for training and device assessment. Clots properties have shown to play

IV Thrombolysis Facilitates Interventional Reperfusion in Non‐Cardioembolic but Not Cardioembolic Stroke

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Intravenous thrombolysis (IVT) before thrombectomy for ischemic stroke may alter clot structure and procedural performance. We investigated how IVT relates to thrombectomy metrics across stroke etiologies. Methods We performed a time‐to‐event analysis of consecutive patients with anterior circulation large vessel occlusion (acLVO ...

Percutaneous thrombectomy of mural aortic thrombus using intravascular ultrasound guidance

Journal of Vascular Surgery Cases and Innovative Techniques, 2019
Mural aortic thrombus is a challenging clinical problem with significant potential complications. Particularly precarious are situations with involvement of the visceral segment of the aorta. We describe a technique for percutaneous thrombectomy of mural

Primary Multivessel Occlusions Treated With Mechanical Thrombectomy: A Multicenter Analysis and Systemic Literature Review.

, 2020
BACKGROUND AND PURPOSE Acute ischemic stroke caused by primary multivessel occlusions (pMVO) is a rare but devastating disease. Whether multi-target mechanical thrombectomy for pMVO is beneficial remains unknown.

Translational Considerations for Injectable Biomaterials and Bioscaffolds to Repair and Regenerate Brain Tissue

Advanced Healthcare Materials, EarlyView.
The repair and regeneration of brain tissue faces both biological and technical challenges. Injectable bioscaffolds offer new opportunities to stimulate tissue regrowth in the brain by recruiting neural stem cells. Here, the translational issues are reviewed that need to be address to advance this promising new therapeutic approach from the bench to ...

3D‐Nanoprinted Fluidically Steerable Soft Robotic Microcatheters

Advanced Robotics Research, EarlyView.
This work introduces a ∼3‐French (1 mm‐in‐diameter) soft robotic microcatheter fabricated by means of two‐photon direct laser writing. The 3D‐printed microcatheter enables remote, on‐demand steering via microfluidic actuation for guidewire‐free navigation of vascular networks as well as microcatheter‐mediated delivery of fluidic payloads to target ...
