A Soft Micro-Robotic Catheter for Aneurysm Treatment: A Novel Design and Enhanced Euler-Bernoulli Model with Cross-Section Optimization

Emanuele Nicotra, Chi Cong Nguyen, James Davies, Phuoc Thien Phan, Trung Thien Hoang, Bibhu Sharma +7
ICRA 2024poster

Aneurysms, balloon-like bulges in blood vessels, present a significant health risk due to their potential to rupture, leading to life-threatening internal bleeding. Current treatments often involve delivering embolic materials or metal coils to fill these bulges, occluding them from the pressure of…

A Flexible 3D Force Sensor with In-Situ Tunable Sensitivity

James Davies, Mai Thanh Thai, Trung Thien Hoang, Chi Cong Nguyen, Phuoc Thien Phan, Kefan Zhu +6
ICRA 2023poster

Following biology's lead, soft robotics has emerged as a perfect candidate for actuation within complex environments. While soft actuation has been developed intensively over the last few decades, soft sensing has so far slowed to catch up. A largely unresearched area is the change of the soft mater…

A Handheld Hydraulic Cardiac Catheter with Omnidirectional Manipulator and Touch Sensing

Chi Cong Nguyen, James Davies, Mai Thanh Thai, Trung Thien Hoang, Phuoc Thien Phan, Kefan Zhu +6
ICRA 2023poster

Atrial fibrillation (AF) is mostly treated via robotic catheter-based cardiac ablation procedures. Over the last few decades, cables or tendon mechanisms are at the core of available cardiac catheters. Despite advances, the use of cables often results in considerable force loss, nonlinear hysteresis…

Bidirectional Soft Robotic Catheter for Arrhythmia Treatment

Chi Cong Nguyen, Timotius Teh, Mai Thanh Thai, Phuoc Thien Phan, Trung Thien Hoang, Harrison Low +4
ICRA 2022poster

Heart rhythm disorders are becoming increasingly prevalent with population aging. Atrial fibrillation ablation (AFA) is a procedure used to treat an irregular heart rhythm (arrhythmia) that starts in the heart's upper chambers. The AFA works by scarring or destroying heart tissue to disrupt aberrant…

Hydraulically Actuated Soft Tubular Gripper

James Davies, Phuoc Thien Phan, Diana Huang, Trung Thien Hoang, Harrison Low, Mai Thanh Thai +4
ICRA 2022poster

There is an increasing interest in soft robotic grippers as they exhibit an ability to grip objects of differing shapes, sizes, textures, and even deformable materials, all of which present a difficult challenge to traditional rigid grippers. An ideal soft gripper would exhibit universal gripping wi…

Design, Fabrication, and Hysteresis Modeling of Soft Microtubule Artificial Muscle (SMAM) for Medical Applications

Mai Thanh Thai, Phuoc Thien Phan, Trung Thien Hoang, Harrison Low, Nigel H. Lovell, Thanh Nho Do
RA-L 2021

Robotic artificial muscles (RAMs) are promising power sources for medical fields such as surgical robotics. However, existing RAMs are challenged by scalability, material costs and fabrications. The nonlinear hysteresis in fluid-driven RAMs causes oscillations in open-loop systems. To circumvent the
