1. A medical device comprising:
a medicament; and
a component comprising:
a body made of at least an elastomeric material, the elastomeric material having a first color, the elastomeric material being configured to change to a second color different from the first color when exposed to laser irradiation of a wavelength within the range of ultraviolet light;
a film contacting the medicament and covering at least a portion of the body; and
a visible mark at least partially on the portion of the body covered by the film, wherein:
the film provides a barrier between the body and the medicament,
the film has a transmittance at a wavelength within the range of ultraviolet light of at least 5%,
the film comprises a material selected from the group consisting of tetrafluoroethylene, polytetrafluoroethylene (PTFE), ethylene tetrafluoroethylene (ETFE), fluorinated ethylene propylene (FEP), polyvinylidene fluoride (PVF), polyvinylidene difluoride (PVDF), polychlorotrifluoroethylene (PCTFE), perfluoroalkoxy alkanes (PFA), ethylene chlorotrifluoroethylene (ECTFE), perfluoroelastomer (FFPM), fluoroelastomer polymer (FPM), polyethylene (PE), cyclic olefin polymer (COP), cyclic olefin copolymer (COC), polypropylene (PP), and combinations thereof,
the visible mark comprises one or more areas of the elastomeric material having the second color as a result of exposure to laser irradiation, through the film, of the wavelength within the range of ultraviolet light, and
the film, after the laser irradiation through the film, demonstrates no visible degradation and is free of the visible mark.
