Abstract
Device and method for needle penetrating and filling a chamber with a predetermined substance, and hermetically resealing a resulting needle hole in the device by applying radiation thereto. The needle penetrable and resealable portion defines a predetermined wall thickness in an axial direction thereof, and may include a thermoplastic that substantially prevents the formation of particles released into the chamber from the needle penetrable and resealable portion during penetration by and withdrawal of the needle. Such thermoplastic may include a predetermined amount of pigment that allows the thermoplastic to substantially absorb laser radiation at a predetermined wavelength, substantially prevent the passage of radiation through the predetermined wall thickness thereof, and hermetically seal a needle aperture formed in the needle penetration region thereof in a predetermined time period.
