Catheter Friction Testingon the Multi Function Tribometer, MFT-5000

Down Force Control

The applied forces can be controlled to mN ranges.
The force can be maintained constant or changed
during the test.

capForce Sensor

Patented Ultra High Resolution capacitance based
sensors introduced for the first time in tribology
for reliable and accurate force characterization tomicroNewton levels on real world samples.
Rtec-Instruments’ Multi Function Tester combinedwith patented capForce sensors allows unprecedented lubricity characterization of catheters. Lubricity isa critical factor effecting insertion force, push force/navigation force, removal force, and over all performance of the catheter.
The MFT-5000 combines multiple techniques in one
platform to evaluate the effect of surface coatings andtexture on catheter lubricity. The closed-loop down
force control allows conformal contact throughout
the test. The open platform allows test set ups fordifferent geometries and orientations with options
for simultaneous testing for multiple samples.
Advanced Capacitance Sensors, In-line Confocal profilometer and Integrated Probe for Coating Thickness
provides comprehensive surface analysis in one toolwith options to produce Friction Maps.

Flexible Test Set Ups

Multiple options to test real components in conformal contact to characterize push force, navigation
force and catheter lubricity

Environmental Controller

Test under controlled humidity, temperature andliquid media.

In-line Confocal Imaging

Characterize effect of texture and surface profile on
lubricity and performance including insertion andremoval forces.

Coating Thickness

Independent spectroscopy based probe to characterize coating thickness & uniformity.

Comprehensive Software

Integrate Surface Profile, Coating thickness & Tribology data to produce Friction maps.

The tester comes with a powerful operation, statistical andimage analysis software. All software are windows based
and are very easy to learn and operate. The software allows
to run the tool in advanced mode for experienced users orjust push a button mode for new users or operators. The
data can be saved in proprietary format or in ASCII format.
