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.
