A Study of the Indian Valve for Ventriculo-atrial Shunts in the Treatment of Hydrocephalus

Abstract
Because of the high costs of importing commercially-available shunts, a hand-made ventriculo-atrial shunt was devised in India for the treatment of hydrocephalus. Modifications have been made to the original design and these shunts are now being produced commercially at a fraction of the cost of other available shunts. Hydrodynamic testing indicates that they compare favourably with the other shunts at present in use.
