6、0 ii BSI 12-1999 Foreword This Part of BS6788 has been prepared under the direction of the Health Care Standards Policy Committee, and is the second Part of BS6788 to be published. BS6788-1 covers hydrocephalus shunts. The neural stimulators covered by this Part of BS6788 comprise two types, categor

7、ized according to the power source of the component that generates the stimulating current, as follows. a) Implant pulse generators. These are self-contained pulse generators having an internal power source, and which may be controlled or adjusted by radio-frequency (RF) or magnetic signals produced

8、 by an external programmer. b) Implant RF receivers. These require RF activation from an external source and therefore the implanted component usually contains no power source (although one may be fitted as a stand-by). Implant RF receivers are activated by external equipment which comprises an RF d

9、river and antenna. The RF driver, together with its power source, is usually housed in a portable container (the transmitter). The antenna may be integral with the transmitter or connected to it by a cable. It is intended to be placed next to the skin, near to the implanted RF receiver. In both type

10、s of stimulator, an implantable lead(s) is normally provided to carry current from the implant pulse generator or implant RF receiver to the stimulation electrodes. These leads may be integral with the generator or receiver, or may be separate. The leads may carry connectors, or separate connectors

11、and adaptors may be used. This Part of BS6788 applies to cables, leads, connectors, adaptors and electrodes whether they form part of an integral device or are separate components of a system capable of being assembled together. The purpose of this Part of BS6788 is to ensure that the neural stimula

12、tor or component thereof is adequately packaged and that the device and the packaging is labelled with sufficient information. This information needs to be readily available to the patient, surgical team and engineer so as to facilitate decision-making on such matters as the choice of device, the me

13、thods of implantation, adjustment and fault diagnosis and to convey user precautions. Therefore, this Part of BS6788 does not specify indications or contraindications for the use of implantable neural stimulators, nor does it specify methods of construction or testing or what the range of normal ope

14、rating variable parameters should be. It does, however, require that information on these matters be included in the documentation accompanying each implant pulse generator or implant RF receiver. The preparation of further Parts of BS6788 to cover other neurosurgical implants is under consideration

15、. It is recommended that implantable neural stimulators and components should be manufactured in accordance with the recommendations in the “Guide to Good Manufacturing Practice for Medical Equipment” 1) . 1) Published by the Department of Health and Social Security, and available from Her Majestys

Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations

20、r implantable neural stimulators intended for stimulation of the central nervous system (brain, spinal cord and adjacent structures). It also covers implanted or external ancillary components, including the external control and driving equipment used for the activation or adjustment of neural stimul

21、ators. This Part of BS6788 does not cover external nerve, muscle or electroconvulsive stimulators, radio-frequency (RF) diathermy or stereotaxic lesion-generating equipment, or percutaneous stimulating electrode assemblies or components.
