Coil Knotting during Endovascular Coil Embolization for Ruptured MCA Aneurysm [PDF]

Interventional Neuroradiology, 2008
Complications during coil embolization of cerebral aneurysms include thromboembolic events, hemorrhagic complications related to procedural aneurysmal rupture and parent vessel perforation, and coil-related complications. The present report describes a rare coil-related complication involving spontaneous coil knotting.

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 ...

Optimization of Magnetic Milli‐Spinner for Robotic Endovascular Intervention

Advanced Robotics Research, EarlyView.
This work presents the design optimization of a multifunctional magnetic milli‐spinner for high‐speed propulsion and efficient clot debulking. The optimized design achieves an ultrafast swimming velocity of 55 cm/s (≈175 body lengths/s) in saline water, enabling stable upstream swimming against strong physiological flows and establishing magnetic milli‐

Endovascular Coiling of the Ophthalmic Artery in Pigs to Induce Retinal Ischemia

, 2011
PURPOSE. The authors recently showed that the retinal circulation can be accessed by transfemoral endovascular catheterization. The purpose of this study was to examine whether endovascular coiling can be used to induce different degrees of ischemic ...

Initial experience with in vivo “endovascular shaping” technique that utilizes the vascular configuration for small cerebral aneurysm coiling [PDF]

, 2020
2020-05Optimal shaping of a microcatheter tip is a key factor in cerebral aneurysm coiling. However, safe cannulation and stabilization of a microcatheter can be technically challenging with small aneurysms requiring precise microcatheter shaping.

Endovascular Coil Embolization of Very Small Intracranial Aneurysms [PDF]

Korean Journal of Radiology, 2010
We aimed to evaluate the results of endovascular coil embolization for very small aneurysms (or= 4), with no bleeding of the treated aneurysms during a mean follow-up period of 13.3 months. On 27 follow-up MRA, there was no recurrence, and the five incompletely occluded aneurysms showed a spontaneous amelioration resulting in an adequate occlusion.Coil
