DualBore Cannulas

MedOne coaxial Dual Bore cannulas allow injection of a fluid, such as prefluorocarbon or staining dye while simultaneously allowing pressure release via passive egress of fluid through the vent hole in the outer lumen. MedOne utilizes an extremely thin-walled inner cannula for an excellent flow rate, even for 27g cases.

DualBore SideFlō® Cannula

The MedOne DualBore SideFlō® Cannula (US Pat 9,937,300) is designed to increase safety by using a side port for fluid injection, eliminating possible retinal injury caused by a fluid jet stream.There are multiple fluid egress vents to allow double the outflow over the previous model for faster pressure relief during injection. The all-metal exterior allows easy entry through valved cannulasystems. MedOne's filled hub design decreases air bubbles during PFCL injection so you can complete the case without interruption.

Optimized for injection of PFCL, staining dyes, or other liquids in small-gauge vitrectomy surgery.
