The new Active Redirection Transit Time (ARTT)
Flowmeter module introduces
several major improvements in the accurate measurement of
volume blood flow. The
module, which operates on ultrasonic transit-time principles,
utilizes a patented
technique of biased insonication and active redirection of ultrasound
to measure
cardiac output in experimental animals. Furthermore, the use of biased
insonication
compensates for adipose tissue intrusion between the probe and vessel during
the
course of chronic implantation.
Most important in this advancement is the development of Triton's "X probe."
The
new probe, which works exclusively with the ARTT Flowmeter module, was
developed to
correct the difficulties of size, weight and signal strength commonly
found with existing
probe designs. Active Redirection permits an ultrasonic signal to
be transmitted in the
shape of an "X" path across a vessel when measuring blood
flow. It is this
extended transmission path which provides better resolution with a
shorter, more compact
probe then previously possible. In comparison, existing
probes, which use single path or
reflecting double path designs, have not been able to
achieve this degree of compactness
and ease of implantation. Further reduction in
probe mass is achieved through the use of
micro-machined Ultem probe bodies. This
material is extremely strong and lightweight, and
complies with US Pharmacopeia
Class VI bio-compatibility requirements .
A growing family of probe sizes is available to fit most commonly instrumented blood
vessels. The probes provide a snug fit, insuring excellent sound coupling in both acute
and chronic preparations. Moreover, the smooth precision machined surfaces of the
cuff
eliminate the risk of vessel erosion in long-term chronic preparations. Specialized
in-line transducers are available for monitoring fluid flow in extracorporeal perfusion
lines.
Calibration for both the implantable and extracorporeal transducers is achieved by
precision delay lines and digital
look-up tables in the Model 300-206 internal circuitry.
The ARTT flowmeter automatically detects the type and
size of probe attached to itself
digital and generates a series of voltages directly proportional to blood flow displayed
on its large LCD panel.
Implantable probes designed for chronic and acute use with the Model 300-206 and
200-206 Active Redirection
Transit Time (ARTē) Flow modules. Probe
size is based on internal diameter to the nearest integer mm. 306 series
probes have a 40
cm miniature twin-axial cable. Requires accessory cable 200-397 or 200-398. Optional
connectors available; Triton skin button or bullet must be specified upon
ordering.
