Making Physiology Happen


RS-IBPFOx-RA Expandable Fiber Optic Catheter, BP System

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 fluid-flled catheters and are generally more suitable for measuring intracardiac pressures from animal species with high intrinsic heart rates.

RS-IBPFOx-RA  Systems include:

Available in 1–4 channel confgurations.

Optional Add-Ons

LabScribe Blood Pressure Module

LabScribe Blood Pressure Module LS-30BP The LabScribe Blood Pressure Module acquires and analyzes data from blood pressure transducers. Data can be analyzed from ventricular and arterial signals in real-time. The software automatically calculates common indices of function from the blood pressure signal where it can easily be exported to another program for further analysis.
