RISThe Effect of Over-Rotating Nickel–Titanium Medical Retrieval Device Guidewires—Part I: Key Parameters Causing Kink Formation Resulting in Premature and Catastrophic Failure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. A variety of Nitinol-based endovascular mechanical devices have been utilized to capture and retrieve blood clots and foreign objects such as embolic coils that occasionally escape during aneurysm treatments and ...
Comparison Among Different High Porosity Stent Configurations: Hemodynamic Effects of Treatment in a Large Cerebral Aneurysm
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Whether treated surgically or with endovascular techniques, large and giant cerebral aneurysms are particularly difficult to treat. Nevertheless, high porosity stents can be used to accomplish stentassisted coiling and ...
Hemodynamic Characterization of Geometric Cerebral Aneurysm Templates Treated With Embolic Coils
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Embolic coiling is one of the most effective treatments for cerebral aneurysms (CAs), largely due to the hemodynamic modifications that the treatment effects in the aneurysmal environment. However, coiling can have very ...
