US Patent:

20110137263, Jun 9, 2011

Filed:

Oct 29, 2010

Appl. No.:

12/915850

Inventors:

Edgar G. Ashmead - Lincoln University PA, US
Edward C. Gunzel - Oxford PA, US
Michael P. Moritz - Media PA, US

International Classification:

A61M 5/315

US Classification:

604230

Abstract:

A syringe stopper that is suitable for use in syringes without silicone oil or other liquid lubricants. The invention provides a low friction barrier between an elastomeric stopper material and a therapeutic in the syringe. The barrier may inhibit materials from leaching from the elastomer material or from extraction of compounds from medicants by the elastomer. A process is also described that allows for molding thin barrier layers while allowing adequate bonding with the elastomer.

Abstract:

A container having a barrier layer is provided. The container may be of thermoplastic and the barrier may inhibit materials from leaching from the thermoplastic material or from extraction of compounds from medicants by the thermoplastic. A process is also described that allows for molding thin barrier layers as container lines and for forming thermoplastic containers with barrier liners.

US Classification:

53426, 604187, 134 30, 134 19, 29434

Abstract:

A method of making a syringe assembly includes providing a first syringe component defining a first sliding surface that is substantially free of lubricant. The first sliding surface is contacted with water. The first sliding surface and the water in contact with the first sliding surface are heated at a temperature of at least 121 C. The first sliding surface is dried.

International Classification:

A61M 5/315
A61M 5/32
A61K 35/12
A61K 38/48

Abstract:

A pre-filled syringe having containing therein at least one therapeutic is provided. The syringe contains a silicone free barrel and an elastomeric syringe stopper that is covered with an expanded polytetrafluoroethylene barrier layer. The presence of a barrier layer that is at least partially porous on the outside of the syringe stopper improves the seal between the stopper and syringe barrel and minimizes the sliding force. In some embodiments, the barrel is formed of a glass material such as a borosilicate glass, that is free of silicone or other lubricants.
