Systems include catheters, an amplifier/signal conditioner, data recorder and software.

Fluid-Filled Catheter Systems

Advantages:

  • Economical and accurate device used to measure direct arterial or venous pressure in animals using the fluid-filled catheter technique. A precision laser-trimmed chip provides accurate and linear measurements over a broad range of pressures. Pressure changes in the vessel are transmitted within the fluid-filled tube to the pressure transducer and acquired for monitoring and further analysis.
  • Tubing as small as 1 mm in outside diameter can be used, making this technique well-suited for measuring pressures in very small vessels.
  • Suitable for mice and larger animals.

Solid-State Pressure Tipped Catheter Systems

iWorx offers A-BP-CATH-16 a 1.6F catheter-tipped solid-state pressure catheters .

Advantages:

  • High frequency response, making it the most sensitive and precise method for the monitoring of arterial pressure and for analysis of changes in the phasic arterial pressure waveform.
  • Superior sensitivity and temporal resolution compared to fluid-filled catheters make them more suitable for measuring intra-cardiac pressures from animal species with high intrinsic heart rates.
  • Unlike the fluid filled catheters, solid state catheters do not require flushing and do not have the problem of decreasing signal intensity with increasing catheter length.
  • Suitable for Rats and larger animals

Fiber Optic Pressure Catheter Systems

iWorx offers the Opsens Fiber Optic pressure catheters in sizes starting at 1.0F.

Advantages:

  • Small 1.0F cathers suitable for Mice and larger animals
  • Since they are fiberoptic, they are suited for MRI applications.
  • High frequency response, making it the most sensitive and precise method for the monitoring of arterial pressure and for analysis of changes in the phasic arterial pressure waveform.
  • Superior sensitivity and temporal resolution compared to fluid-filled catheters make them more suitable for measuring intra-cardiac pressures from animal species with high intrinsic heart rates.
  • Unlike the fluid filled catheters, solid state catheters do not require flushing and do not have the problem of decreasing signal intensity with increasing catheter length.

Non-Invasive Blood Pressure Systems

Invasive measures of pressure are not always possible and, as a result, there may be a need for non-invasive methods to detect pressure. The most widely accepted technique for animals is the tail-cuff method. iWorx offers the new IITC Non-Invasive Blood Pressure Systems for mice and rats. The IITC Life Science tail cuff system is a compact, integrated single unit which includes a warming chamber, restrainer and tail cuff.  The system is controlled by a built in touch screen interface with controls for temperature, test cycle, cuff inflation, cuff calibration and various test parameters.  Up to 200 systems can be daisy chained to record independently or simultaneously.  Data can be downloaded directly onto a USB thumb drive while also being acquired via analog output by LabScribe software for further analysis.  Various sizes of restrainers and tail cuffs are available to suit a variety of research models.

Software

iWorx offers several solutions for measuring pressure including fluid‐filled pressure transducers, catheter-tipped micro pressure sensors and non‐invasive tail cuff pressure systems. LabScribe software with the Blood Pressure Module provides built‐in software routines to perform a number of arterial and ventricular pressure calculations.

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.
