HC Deb 11 May 1971 vol 817 cc83-4W
Mr. Carter-Jones

asked the Secretary of State for Education and Science what is the weight of the Hendon Arm, supplied under the National Health Service; what is working time on the patient before the gas cylinder needs changing; how many children have now been fitted; how many times per patient these arms have failed; and if she will make a statement.

Mrs. Thatcher

The Hendon Arm is not yet supplied under the National Health Service. It is only at the prototype stage and is currently being evaluated by a working party, set up by the Medical Research Council, which is monitoring clinical trials and expects to be able to report next year.
