You company is going to make a new elastomeric copolymer cat

You company is going to make a new elastomeric copolymer catheter for a hydrocephalic shunt that will drain fluid from a brain ventricle to the abdominal cavity. You are in charge of all in vitro testing to be done, prior to testing the catheter in animals. It is important to be as thorough as possible. What tests do you recommend? What results do you hope to get? (No specific numbers are needed.)

Solution

The tests on the new material of catheter include,

1. Bio compatibility - to suit the person\'s physical and biological conditions without ill side effects.

2. Heat sensitivity - Should be insensitive to temperature fluctuations

3.Stiffness: Should not have a permanents set of distortions.

4. Ease of insertion and modifying: should be flexible

5. Tensilie strength: Should take unexpected loads and should not fail.
