The idea of giving TRAVAIL is to provide single solution to the doctor where there are no facilities available. There are wide range of materials with which the disposable as made. For an example, a Catheter made of low quality polypropylene (PP) will present sperm adhesion to it walls or a hard catheter might scrape the endometrial layer while inserting or a techniques like sterilisation with ethylene oxide might kill the sperm or impair its motility. 

TRAVAIL kit is supplemented with all quality tested disposables for one complete procedure so that the doctor doesn't have to look for individual vendors to get the things.
