Selectively Actuated Fiberbots for High-precision Minimally Invasive Surgery
Jinshi Zhao, Libaihe Tian, Alex Ranne +9
Long, slender instruments are essential for minimally invasive surgery (MIS), but achieving precise distal manipulation becomes increasingly difficult when actuation extends along…
Modular Robotic Catheters for Endovascular Aneurysm Repair
Alex Ranne, Jinshi Zhao, Ali Anil Demircali +5
Fenestrated/Branched endovascular aneurysm repair (FEVAR/BEVAR) require surgeons to navigate catheters and guidewires into various branches of the abdominal aorta, before deploying…
A Mapping Sheath with Thermally Drawn Multi-Electrode Basket for Cardiac Electrophysiological Recording and Ablation Catheter Delivery
Qindong Zheng, Anil Demircali, Jinshi Zhao +14
Cardiac arrhythmias, particularly atrial fibrillation, represent a major cardiovascular health burden and underscore the need for efficient and integrated strategies for electrical…
Model selection and real-time skill assessment for suturing in robotic surgery
Zhaoyang Jacopo Hu, Alex Ranne, Alaa Eldin Abdelaal +4
Automated feedback systems have the potential to provide objective skill assessment for training and evaluation in robot-assisted surgery. In this study, we examine methods to achi…
Thermally Drawn Bioelectric Catheters: Enabling Proprioceptive Endovascular Navigation
Alex Ranne, Heiko Maier, Jinshi Zhao +6
To navigate medical instruments safely and accurately inside a patient's vascular tree, combining X-ray fluoroscopy with intermittent contrast injections is the gold standard. Howe…
Malleable Robots
Angus B. Clark, Xinran Wang, Alex Ranne +1
This chapter is about the fundamentals of fabrication, control, and human-robot interaction of a new type of collaborative robotic manipulators, called malleable robots, which are…
CathFlow: Self-Supervised Segmentation of Catheters in Interventional Ultrasound Using Optical Flow and Transformers
Alex Ranne, Liming Kuang, Yordanka Velikova +2
In minimally invasive endovascular procedures, contrast-enhanced angiography remains the most robust imaging technique. However, it is at the expense of the patient and clinician's…
AiAReSeg: Catheter Detection and Segmentation in Interventional Ultrasound using Transformers
Alex Ranne, Yordanka Velikova, Nassir Navab +1
To date, endovascular surgeries are performed using the golden standard of Fluoroscopy, which uses ionising radiation to visualise catheters and vasculature. Prolonged Fluoroscopic…
Identifying visible tissue in intraoperative ultrasound: a method and application
Alistair Weld, Luke Dixon, Giulio Anichini +4
Purpose: Intraoperative ultrasound scanning is a demanding visuotactile task. It requires operators to simultaneously localise the ultrasound perspective and manually perform sligh…
