A Sleeve Alters the Pressure‐Stretch Curve of a Hyperelastic Balloon to Enable Pre‐Programmed Sequencing

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
This article demonstrates that encasing a hyperelastic balloon in an inextensible sleeve greatly increases its burst pressure. This simple mechanical behavior can be used to produce an asymmetric inflation‐deflation sequence for coupled balloons with different thicknesses so they could serve as a soft robot's rear and front anchors when driven from a ...

Untethered Magnetic Microswimmers for Targeted Particle Transport and Flow Manipulation

Advanced Materials Technologies, EarlyView.
This work introduces magnetically actuated microswimmers to dynamically reconfigure fluid flow within a single microfluidic device. Multiple homogeneous microswimmers are independently controlled by an external magnetic field to perform translational and rotational motions, thereby inducing real‐time flow manipulation.

Transcatheter Aortic Valve Durability: Focus on Structural Valve Deterioration

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Transcatheter aortic valve replacement has emerged as a valuable alternative to surgical aortic valve replacement in patients with severe aortic stenosis. Given the expansion of transcatheter aortic valve replacement to lower‐risk and younger populations

Transcatheter aortic valve replacement

Nursing Critical Care, 2019
Abstract: Transcatheter aortic valve replacement (TAVR) is indicated in some patients with severe aortic stenosis for whom surgical intervention is not deemed appropriate. This article explores when TAVR may be the preferred treatment option over surgical aortic valve replacement and discusses various prosthetic valve devices.
