widely used to measure forces

*Other Crimp Head Designs
-Researched how other crimp head designs measured the forces felt in the crimp head. See Patents of other designs to the left.

U.S. Patent # 6,840,081 B2

*Pressure Transducers
-what is a Pressure Transducer? click here.
-Converts pressure reading into voltage reading

*Non-contact Sensors
-Laser Sensor
-Ultrasonic Sensors

Load Cells - Currently used by MSI to measure force stent feels in
Crimp Head. Click here for more info. on Loads Cells!

*Rubber Materials
-Researching clean room approved rubber that have properties that will fit our Rubber Design concept. Silicone based rubber and

S. Patent

*Stent Hoop Forces. Click here for more info.

*Strain Gauge Load Cells
-may be helpful in measuring force in crimp head

*Medical Safe Materials & Cleanroom Standards
-Our device will be used in clean rooms and in the crimp head which is where the stent is also in contact with. We need to be sure that the materials we use meet clean room standards.
