Subretinal Cannulas: PolyTip Cannulas | Extendable | Tapered PolyTip | Tapered Cannula

 

Subretinal PolyTip® Cannulas

The 38g PolyTip® Cannulas utilize an extremely thin-walled, semi-flexible tip which allows maximum flow rate in a small diameter cannula. They are rigid enough to penetrate the retina, eliminating the need to create a separate retinotomy. These products are ideal for subretinal injection. They can also be used for low volume fluid drainage, such as draining subretinal PFCL. The luer lock hub allows a quick secure connection to a syringe, extension tube or infusion line.

 The 2mm green tip allows easy passage through valved entry cannulas and better visibility. The shorter tip is rigid enough to penetrate the retina, while the 5mm is more flexible.

Extendable PolyTip® Cannulas

The Extendable PolyTip® Cannulas feature a 38g tip that can be fully retracted for easy passage through a valved entry cannula, and then extended up to 5mm in length. Shorter tubing reduces loss of injection fluid. Priming volume is approximately 0.1mL.

3262 PolyTip® Cannula 25g /33g 25g x 28mm cannula with 33g x 2mm tip 33g tip can be used for penetration through the retina, allowing drainage of subretinal fluid through a minimally traumatic drainage retinotomy. Thin wall tip has flow rate similar to a 25g soft tip but with a smaller retinotomy. Green tip allows excellent visibility.

The Micro Cannulas has a 40g (0.10mm diameter) beveled tip. Metal cannula with beveled tip allows easy penetration through the retina for subretinal injection. Slight curve at tip allows great visibility of tip and easier approach angle for entry into subretinal space. Compatible with 25g entry cannulas.
