Abstract

Balloon catheter consists of an elongated balloon which is pushed with an open end over the catheter hose. Its other end is attached to a rounded insert in which a support rod extends along the centre line of the balloon and into part of the hose. A disc on the rod acts as a support when the balloon is twisted up by turning the rounded insert until its dia. equals that of the hose. This process can be assisted by applying a vacuum to the hose. In this position, a sleeve can be pushed over the twisted balloon to retain its shape as inserted in a vein or other body cavity. Catheter can be pushed through narrower and more curved passages without risk of injury.
