MONOLITHIC IN-SITU FORMING VALVE SYSTEM

摘要

Described is a monolithic in situ forming valve system. The valve system is delivered in an unformed, collapsed configuration that lacks any functional characteristics commonly associated with a valve before. However, once expanded, the system is transformed into a competent valve for use in a wide variety of applications. The valve system includes a superior expandable structure, an inferior expandable structure, and a helical pre-valve component. The helical pre-valve component comprises a first end attached with the superior expandable structure and a second end attached with the inferior expandable structure. The helical pre-valve component is formed such that expansion of the superior expandable structure and the inferior expandable structure causes the helical pre-valve structure to transform into a functional valve held between each of the expandable structures.
