Valved latex balloons and water-soluble contrast opacified polymer. Simple detachable balloon system.
Latex balloons of different shapes, sizes and volume, incorporating a simple valve mechanism, were produced cheaply. These balloons are ethylene oxide sterilized and are available on 'the shelf' for use at any time. A contrast soluble polymer consisting of 2 hydroxy-ethyl-methacrylate, a cross linker, Iopamidol and water-soluble free radical curing system has been developed. The polymer sets in 10 minutes and there is no 'dead volume' problem. The balloons and polymer were evaluated in dog arteries, including histologic studies and have been subsequently used in 7 patients without any complications.
