ALZET Catheters

Via a catheter, ALZET® Osmotic Pumps can deliver substances into vessels, spinal cord, cerebral ventricles and brain parenchyma, and other organs or tissues. DURECT Corporation offers a range of specialized catheters, compatible with ALZET pumps, to enable targeted delivery to a variety of sites. ALZET pumps can be attached to catheter tubing with I.D ranging from 0.58 mm to 0.76 mm (0.023"-0.030").
