MD Craft offers the Instaview series cannulas that have patented quick valve sealing assembly that allows advencing both of the guidewire and contrast medium within a single lumen.
This mechanism allows contrast medium to be injected smoothly even while the guidewire is passed through the sheath.
The metal ball tip aids in difficult cannulation and allows for easy changes in direction of the biliary and pancreatic orifices. The radiopaque tip can easily be visualized on fluoroscopy.
Pre-curved cannulas can be angulated as much as 90° when the handle is pulled, and as much as 30° when pushed, ensuring easy insertion into the papilla and biliary ducts, even in challenging cases. It makes insertion into the intra-hepatic ducts simple and straightforward.
