This specification contains requirements based on state-of-art science and technology as applicable to various considerations that have been identified as important to ensure reasonable safety and efficacy as it relates to the biocompatibility and the mechanical integrity of the device components in soft tissue expander devices.

This specification is not intended to limit the science and technology that may be considered and applied to ensure performance characteristics of subject device in intended applications. When new information becomes available or changes in state-of-art science and technology occur and relevance to subject devices has been established by valid science, it is intended that this specification will be revised in accordance with ASTM guidelines.

This specification covers the requirements for single use saline inflatable, smooth and textured tissue expansion devices to be used intraoperatively or implanted for typically less than 6 months and then removed. This specification applies only to soft-tissue expander devices fabricated with elastomer shells. It does not necessarily cover any custom fabricated soft tissue expander device manufactured to any other specification. The device shall be classified as: Type I; Type II; and Type III. Biocompatibility, tensile set, breaking force, tubing shell junction, injection port competence, overexpansion, tubing length adapter strength, needle stop penetration, and fused or adhered joints tests shall be performed to conform with the specified requirements.
