ABSTRACT:
A self-healing seal is provided which is particularly adaptable for use in medical applications. The seal includes a housing which defines an interior volume. The housing is formed of a rigid or semi-rigid material such as a rubber or other elastomeric material. A viscous flowable material is disposed within, and substantially fills, the interior chamber of the housing. The viscous flowable material is typically a gel, such as silicone gel. The self-healing seal is configured such that if it is penetrated by an object such as a hypodermic needle, when the needle is subsequently removed, the viscous flowable material flows in such a manner as to fill the space previously occupied by the penetrating object. At the same time the housing is sufficiently elastic to maintain the viscous material within the interior volume of the housing. In this manner a liquid impermeable seal is formed.
