Abstract In minimally invasive surgery, such as cardiac ablation, magnetically steered catheters made of variable‐stiffness materials can enable higher dexterity and higher force application to human tissue. However, the long transition time betwee

Abstract Variable stiffness catheters are typically composed of an encapsulated core. The core is usually composed of a low melting point alloy (LMPA) or a thermoplastic polymer (TP). In both cases, there is a need to encapsulate the core with an ela

Abstract Patients suffering from heart failure often require circulatory support using ventricular assist devices (VADs). However, most existing VADs provide nonpulsatile flow, involve direct contact between the blood flow and the device's lumen and

One of the challenges of minimally invasive surgery is the dexterous manipulation and precise control of small‐diameter continuum surgical instruments. Herein, a magnetic continuum device with variable stiffness (VS) is presented, whose tip is prec

In remote magnetic navigation, a magnetic navigation system is used to generate magnetic fields to apply mechanical wrenches to steer a magnetic object. This technique can be applied to navigate untethered micro- and nanorobots, as well as tethered m

Cardiac arrhythmia refers to a condition of an abnormal or irregular heartbeat, which usually results in disturbed blood flow. This can lead to a reduced cardiac output and an increased risk for blood clot formation, which can cause life-threatening
