Resealable containers and assemblies for filling and resealing same

A resealable member for sealing a predetermined substance within a device, wherein the device is usable in a filling assembly including a filling member for penetrating the resealable member and introducing a substance therethrough and into the device, a substance source coupled in fluid communication with the filling member for introducing the substance through the filling member and into the device, and a laser source connectable in thermal communication with the resealable member, wherein the resealable member comprises:

• a body defining a predetermined wall thickness, a penetrable region that is penetrable by the filling member and is heat resealable to hermetically seal an aperture therein by applying laser radiation from the laser source at a predetermined wavelength and power thereto, wherein the penetrable region defines a predetermined color and opacity that (i) substantially absorbs the laser radiation at the predetermined wavelength and substantially prevents the passage of the radiation through the predetermined wall thickness thereof and (ii) that causes the laser radiation at the predetermined wavelength and power to hermetically seal the aperture formed in the penetrable region thereof in a predetermined time period to, in turn, seal the substance in the device from the ambient atmosphere.
