Elastic plug assembly for medical device
First Claim
1. A medical device, comprising:
- an inlet formed from an elastic material;
a rigid plug retainer disposed in the inlet, the rigid plug retainer being radially compressed and surrounded by the elastic material of the inlet to prevent longitudinal movement of the rigid plug retainer; and
a compressible elastic plug disposed in the rigid plug retainer, the compressible elastic plug being radially compressed and surrounded by the rigid plug retainer to ensure that any hole in the compressible elastic plug caused by a needle being inserted therein is substantially closed after the needle is withdrawn.

Abstract
An elastic plug assembly is provided for selective penetration by a needle. The elastic plug assembly comprises an elastic plug that is retained in a radially compressed state by a rigid plug retainer. The combined elastic plug and rigid plug retainer may be secured in a housing formed from an elastomeric material. The elastic plug may be penetrated by a needle. Upon removal of the needle, the radially compressed elastic plug will be urged toward its compressed condition with the space that had been occupied by the needle being completely filled to effectively achieve the sealing function of the plug. Needles may repeatedly be penetrated through the plug and removed as necessary, and the plug will efficiently return to its substantially solid sealed state after each successive needle removal.
