We designed a catheter with a balloon at the tip for occlusion of both common iliac arteries through which the antegrade flow was allowed by an iliac to femoral arterio-arterial shunt connected to an in-line filter.
Basilar tip and bilateral PCA occlusion cause ischemic injury in the medial aspect of both temporal lobes and/or the midbrain and thalamus.
Then the filament tip was positioned for occlusion at a distance of 6mm beyond the internal carotid artery-pterygopalatine artery bifurcation.
In line with the Department of Health guidelines (2007), open ear tip technology that avoids occlusion and makes use of residual hearing would be used for a mild hearing loss with and without tinnitus (Del Bo et al. 2006).
The Endoclamp is a 10.5 Fr, 100 cm long, three-lumen catheter with an elastomeric balloon near its tip customized for endoluminal occlusion of the ascending aorta in order to separate the aortic root from arterial circulation.
Phacoemulsification powers were set to 40, 60, 80, and 100%, and aspiration flow rates were set at 0, 1, 2, 3, 4, and 5 ml/min to simulate complete or incomplete occlusion of the tip.
They also profited from these heuristic rules on the curvature difference image to determine a circular RoI that embraces all the components and the nose tip robustly, both even under occlusions and severe pose variations.
After determining the proper microcatheter position for the occlusion, using the radiopaque tip of the microcatheter, the coronary guide wire was pulled out and a mixture of 900-μm microspheres (Embozene, CeloNova BioSciences, Inc., Newnan GA, USA) was flushed into the coronary artery under fluoroscopic control.
Patients sometimes required additional surgeries for several reasons: 1) occlusion of the catheter tip in the intraperitoneal cavity due to tissue growth, 2) battery failures, and 3) skin erosion.
