Epidural catheter fixation. A comparison of subcutaneous tunneling versus device fixation technique
Journal of Anaesthesiology Clinical Pharmacology, 2016 Background and Aims: The technique of securing the epidural catheter has a major bearing on the efficacy of epidural analgesia. Specific fixator devices, for e.g., Lockit epidural catheter clamp, which successfully prevents catheter migration, are ...

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 ...

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.

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 ...

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

Model-based Catheter Segmentation in MRI-images [PDF]
arXiv, 2017 Accurate and reliable segmentation of catheters in MR-guided interventions remains a challenge, and a step of critical importance in clinical workflows. In this work, under reasonable assumptions, mechanical model based heuristics guide the segmentation process allows correct catheter identification rates greater than 98% (error 2.88 mm), and reduction

Towards Automatic Manipulation of Intra-cardiac Echocardiography Catheter [PDF]
arXiv, 2020 Intra-cardiac Echocardiography (ICE) is a powerful imaging modality for guiding electrophysiology and structural heart interventions. ICE provides real-time observation of anatomy, catheters, and emergent complications. However, this increased reliance on intraprocedural imaging creates a high cognitive demand on physicians who can often serve as ...
