Abstract
Syringe assemblies comprising a first cap and a second cap to ensure sterilization of the fluid path without the need for external packaging are described. Also described are methods of sterilizing the fluid path of a syringe assembly.
Claims19
A method of sterilizing a fluid path of a syringe assembly, the method comprising subjecting the syringe assembly to a radiation or a gas, wherein the syringe assembly comprises:
- a barrel including a side wall having an outside surface and an inside surface defining a chamber for retaining fluid, an open proximal end, and a distal end including a distal wall, the chamber, distal end and proximal end defining the fluid path;
- a plunger rod including a stopper disposed within the barrel;
- a first cap having a proximal end having a first segment that is radiation or gas permeable and is in flow communication with the fluid path and permitting sterilization of a portion of the fluid path by the radiation or the gas, and an open distal end affixed to the open proximal end of the barrel, wherein the first cap proximal end is covered by a first permeable material;
- a second cap affixed to the distal end of the barrel, the second cap having a proximal end and a closed distal end having a second segment that is radiation or gas permeable and is in flow communication with the fluid path and permitting sterilization of a portion of the fluid path by the radiation or the gas;
- and
- a collar attached to the closed distal end of the second cap, the collar comprising a second permeable material that extends along an entire length of the second segment.

A method of sterilizing a fluid path of a syringe assembly, the method comprising:
- providing the syringe assembly wherein the fluid path of the syringe assembly is defined by a chamber for retaining fluid, the syringe assembly having an open proximal end, and a distal end;
- a first cap having a proximal end covered by a first permeable material that is radiation or gas permeable and is in flow communication with the fluid path;
- a second cap affixed to the distal end of the syringe assembly, the second cap having a proximal end and a closed distal end that is in flow communication with the fluid path;
- and
- a collar attached to the closed distal end of the second cap, the collar comprising a second permeable material that that extends along an entire length of the second segment, wherein the second permeable material is radiation or gas permeable;
- and
- subjecting the syringe assembly to radiation.
