Fast-Response Variable-Stiffness Magnetic Catheters for Minimally Invasive Surgery

Dario Floreano, Yegor Piskarev, Yi Sun, Jun Shintake, Matteo Righi

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 between soft and rigid ...

A Variable Stiffness Magnetic Catheter Made of a Conductive Phase-Change Polymer for Minimally Invasive Surgery

Dario Floreano, Yegor Piskarev, Jun Shintake

Variable stiffness (VS) is an important feature that significantly enhances the dexterity of magnetic catheters used in minimally invasive surgeries. Existing magnetic catheters with VS consist of sensors, heaters, and tubular structures filled with low me ...

In situ photopolymerizable hydrogels for intracranial aneurysms treatment

Oriane Poupart

Intracranial aneurysm is a cerebrovascular disease characterized by an artery dilation in the brain. An aneurysm is prone to rupture, which causes a life-threatening subarachnoid hemorrhage. The major drawbacks of the current treatments, open surgical clip ...

Simultaneous Recognition and Pose Estimation of Instruments in Minimally Invasive Surgery

Pascal Fua, Raphael Sznitman, Pablo Marquez Neila

Detection of surgical instruments plays a key role in ensuring patient safety in minimally invasive surgery. In this paper, we present a novel method for 2D vision-based recognition and pose estimation of surgical instruments that generalizes to different ...

Nano Fibrillated Cellulose Based Composite Hydrogels for an Injectable Intervertebral Disc Implant

Azadeh Khoushabi

Replacing the gel-like central part of the intervertebral disc (IVD), so-called nucleus pulposus (NP), via a minimally invasive surgery is one of the most recent approaches in the lower back pain treatments. An appropriate biomaterial for NP replacement (N ...
