Z-Shaped Microcatheter Tip Shaping for Embolization of Aneurysms at the Proximal A1 Segment of the Anterior Cerebral Artery: A Technical Note [PDF]
Neurointervention, 2011 Embolization of an aneurysm at the proximal A1 segment of the anterior cerebral artery (ACA) is technically challenging. We treated four consecutive patients with unruptured aneurysms at the proximal portion of the A1 segment of the ACA.

Access via the internal jugular vein [PDF]
, 2008 Central venous access via the internal jugular vein (IJV) is safe, relatively easy and very commonly used in infants and children undergoing cardiac surgery for congenital heart disease. Because of the wide range of anatomical variations an ultrasound-

Advances in procedural techniques--antegrade. [PDF]
, 2014 There have been many technological advances in antegrade CTO PCI, but perhaps most importantly has been the evolution of the "hybrid' approach where ideally there exists a seamless interplay of antegrade wiring, antegrade dissection re-entry and ...

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 ...

In vitro compression of a soft tissue layer on a rigid foundation [PDF]
, 1987 In vitro compression studies have been performed on layers of porcine skin and fat. The tissue layers have been loaded by means of various indentors. Indentor displacements and interstitial fluid pressures have been measured.

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 ...

Genomic and Ecogenomic Characterization of Proteus mirabilis Bacteriophages
Frontiers in Microbiology, 2019 Proteus mirabilis often complicates the care of catheterized patients through the formation of crystalline biofilms which block urine flow. Bacteriophage therapy has been highlighted as a promising approach to control this problem, but relatively few ...
