After ASD generation, animals were randomized into 2 groups (10 sheep/group) for ASD closure using echography as the only imaging modality: traditional guide wire
group (control group) and new ultrasound guide wire
group (study group).
When the positioning accuracy was <1.00 mm, the guide wire
was placed into the sleeve.
Divide-and-Conquer Strategy against Guide Wire
As the radio-opaque metallic tip is seen emerging from the ureteric dilator, the guide wire
is removed, leaving the J stent in optimal position.
Techniques to stabilize the guiding catheter using a balloon as the anchor or guide wire
have been reported previously in the fields of coronary intervention, neurointervention, and endoscopic intervention [5-8].
Those are: (i) guide wire
shadow detection, (ii) plaque boundary detection by using the new modified level set method, and (iii) inference of plaque boundary in the guide wire
shadow region by using the T-S fuzzy model.
The anterior wall does transilluminate well with the light inside the sphenoid sinus cavity, and twirling the guide wire
can confirm that the sinus is cannulated as the light will "dance" or swirl within the sinus.
Procedure was the same as the modified procedure except the section of rendezvous technique which was also described in other reports [5, 10]; a guide wire
was used to pass through the cyst duct and manipulated by the surgeon to pass through duodenal papilla; then the hydrophilic tip of guide wire
was gasped with snare by the endoscopist; with collaborative pushing by the surgeon, the guide wire
was pulled out of endoscope with snare.

In another study done by Yildrim et al in Turkey, compared direct arterial cannulation of radial artery with guide wire
After passing guide wire
(5658, outer diameter 0.035 inch: Boston Scientific Corporation, USA) into the peritoneal cavity, the needle knife was replaced with OTW constant radial expansion (CRE) balloon dilators (5839, outer diameter 0.6-0.8cm; 5842, outer diameter 1.2-1.5cm: Boston Scientific Corporation, USA) for gastrotomy.
