iWorx Fiber Optic Invasive BP system is designed for measuring pressures in animals from mice and other rodents to larger animals.
iWorx offers the Opsens Fiber Optic pressure catheters in sizes starting at 1.0F. These catheters are recommended for measuring pressure in small vessels as well as ventricular pressures in small rodents. They are also highly recommended for recording arterial and chamber pressures in large animals. Being fiberoptic, they are suited for MRI applications as well.
Fiber Optic catheters offer superior sensitivity and temporal resolution compared to fuid-filled catheters and are generally more suitable for measuring intracardiac pressures from animal species with high intrinsic heart rates.
