Sterile resealable vial connector assembly

A connector assembly for a vial having an interior, a neck defining an open top to said vial and an externally threaded annular rim around portions of said neck surrounding said open top, said connector assembly comprising:

• a transfer set having a body with opposed top and bottom ends, at least said bottom end being dimensioned for slidable movement between upper and lower positions in said open top of said vial, a fluid access device extending from said top end of said body and a stopper support extending from said bottom end, a passageway extending through said transfer set from said fluid access device to an opening located on said stopper support, a generally cylindrical skirt supported in spaced relationship around said body, said skirt including an array of internal threads threadedly engageable with said threads on said annular rim of said vial, said threads extending axially a sufficient distance for moving said body between said upper and lower positions in said open top of said vial;
• and
• upper and lower stoppers mounted in spaced relationship on said stopper support such that said opening of said passageway is intermediate said stoppers, said upper stopper being dimensioned and disposed for sealing engagement with said neck of said vial in both said upper and lower positions of said transfer set, said lower stopper being dimensioned and disposed on said stopper support for spaced relationship from the neck of said vial when said transfer set is in said lower position so that said opening of said passageway communicates with said interior of said vial and for sealing engagement with said neck of said vial when said transfer set is in said upper position to seal said opening from said interior of said vial.

• a transfer set having a body with opposed top and bottom ends, at least said bottom end being dimensioned for slidable movement a selected distance between upper and lower positions in said neck of said vial, said stopper support extending from said bottom end of said body, an axial passageway extending through said transfer set from said top end to an opening located on said stopper support;
• and
• upper and lower stoppers mounted in spaced relationship on said stopper support such that said opening of said passageway is intermediate said stoppers, said upper stopper having a length greater than said selected distance of movement of said transfer set between said upper and lower positions and being disposed for sealing engagement with said neck of said vial in both said upper and lower positions of said transfer set, said lower stopper being dimensioned and disposed on said stopper support for sealing engagement with said neck of said vial when said transfer set is in said upper position to seal said opening from said interior of said vial and being spaced below said neck when said transfer set is in said lower position so that said opening communicates with said interior of said vial.
