Improving Catheter Segmentation & Localization in 3D Cardiac Ultrasound Using Direction-Fused FCN [PDF]
arXiv, 2019 Fast and accurate catheter detection in cardiac catheterization using harmless 3D ultrasound (US) can improve the efficiency and outcome of the intervention. However, the low image quality of US requires extra training for sonographers to localize the catheter.

Advanced Healthcare Materials, EarlyView.Biomimetic glycosaminoglycan analog hydrogels exhibit suitable and robust mechanical properties, as well as hemocompatibility and biocompatibility, making them ideal for the embolization of intracranial aneurysms. Notably, the hydrogel's environment‐selective swelling properties enable complete blockage of the aneurysm cavity while preventing ...

Catheter ablation of epicardial ventricular tachycardia
Journal of Arrhythmia, 2014 Ventricular tachycardias (VTs) can usually be treated by endocardial catheter ablation. However, some VTs can arise from the epicardial surface, and their substrate can be altered only by epicardial catheter ablation.

3D/2D Registration of Mapping Catheter Images for Arrhythmia Interventional Assistance [PDF]
P. Fallavollita, " 3D/2D Registration of Mapping Catheter Images
for Arrhythmia Interventional Assistance", International Journal of Computer
Science Issues, IJCSI, Volume 4, Issue 2, pp10-19, September 2009", 2009 Radiofrequency (RF) catheter ablation has transformed treatment for tachyarrhythmias and has become first-line therapy for some tachycardias. The precise localization of the arrhythmogenic site and the positioning of the RF catheter over that site are problematic: they can impair the efficiency of the procedure and are time consuming (several hours ...

Motor‐Free Soft Robots for Cancer Detection, Surgery, and In Situ Bioprinting
Advanced Healthcare Materials, EarlyView.Novel motor‐free soft robots for cancer detection, surgery, and in situ bioprinting–are presented. This master‐slave system is constructed from soft fibrous syringe architectures, removing the need for electrical motors and complex control mechanisms, while reducing the physical tremors.

Non‐Surgical, In‐Stent Membrane Bioelectronics for Long‐Term Intracranial Pressure Monitoring
Advanced Healthcare Materials, EarlyView.This image shows a sequence of long‐term intracranial pressure monitoring using non‐surgical, in‐stent membrane bioelectronics. Abstract Traditional intracranial pressure (ICP) monitoring methods, using intraventricular catheters, face significant limitations, including high invasiveness, discrete data, calibration complexities, and drift issues, which
