High-Fidelity Pressure-Volume
Catheters
- High frequency response maintains signal
integrity and prevents damping or attenuation of signal
- No motion artifact or overshoot as
with conventional fluid-filled catheters
- 10µV/V/mmHg sensitivity provides
higher measurement resolution than any other sensor on the market
- Pressure membrane recessed for protection
- Vented to atmosphere to correct for
barometric pressure
- Pressure and volume at the source from
a single instrument
Polyimide Tubing
- Provides ideal balance of flexibility
and rigidity, ensuring easy insertion and maneuverability
- Will not fray like many other catheter
materials which, over time, will irritate vascular linings and
valves
- Small diameter of tubing minimizes
impact on aortic flow resulting in more physiologic data Smooth
Profile
- Reduces potential damage to endothelial
lining during catheterization
- Allows for easy passage through aortic
valve (can be inserted and withdrawn repeatedly)
|
Variable Segment Length (VSL) Catheters
- Are ideal for use in isolated working
heart studies where typical perfusion solutions (e.g. Krebs-Henseleit)
will have resistivity
different from that of blood
- Have a series of conductance rings
situated proximal to the pressure sensor
- Have up to 4 different segment lengths
(S1, S2, S3, S4) that can be placed on one catheter providing
versatility when studying hearts of different sizes
- VSL hardware allows for easy and quick
selection of any one of the 4 segments on the catheter to be
used for measuring volume VSL Pressure-Volume Control Box
- For use with standard P-V and VSL catheters
- Can be used with solutions of different
conductivity to blood (e.g. Krebs-Henseleit)
- Has adjustable gains and offset to
be used with ANY conductive medium with various-sized rodent
hearts
- Analog output for compatibility with
a range of data acquisition systems, see Section I Physiology
for options
