The reported event was inconclusive.No sample was returned for evaluation and the root cause was undetermined.The device history record was reviewed and found nothing that could have caused or contributed to the reported event.The instructions for use were found adequate and state the following: ¿brachysource® seed implants in mick® cartridges are brachysource® seed implants loaded into mick® cartridges (1-20 brachysource® seed implants per cartridge) and are designed for use with the mick® 200-tpv applicator and with applicator implant needles supplied for use by bard.Per the customer¿s request, the order may also contain calibrated or loose brachysource® seed implants in a separate screw-cap vial, and individual packets of sourcelink® connectors (see the sourcelink® connector information for use for further information regarding sourcelink® connectors).All components are provided sterile.Physical characteristics brachysource® seed implants consist of a welded titanium capsule containing iodine-125 adsorbed onto a nickel/copper coated, gold cored aluminum wire.Iodine-125 has a half-life of 59.6 days1 and decays by electron capture with the emission of characteristic photons and auger electrons.The principal photon emissions are 27.4 and 31 kev x-rays and a 35.5 kev gamma.The titanium wall of the brachysource® seed implants absorbs the electrons.In-vivo characteristics clinical efficacy derives solely from the interaction of the emitted ionizing radiation from the brachysource® seed implants with the tissue being treated.Titanium encapsulation provides good biocompatibility.Total photon transmission is approximately 59%2 after accounting for attenuation by the titanium capsule and the radio-opaque solid substrate.Dose distribution around brachysource® seed implants is moderately anisotropic, as is common with other brachytherapy sources,3,4,5 and should be accounted for in dose calculations.Indications brachysource® seed implants are indicated for permanent interstitial treatment of selected localized tumors such as: head and neck, lung, pancreas, and early stage prostate.Brachysource® seed implants may be used in superficial, intra-abdominal and intra-thoracic locations.Brachysource® seed implants are indicated to treat residual tumors following completion of a course of external radiation therapy and for recurrent tumors.Contraindications as with other brachytherapy sources, treatment of tumors in generally poor condition [e.G.Ulcerated] is not recommended with brachysource® seed implants due to the potential of brachytherapy source migration." correction:d4 h11:section a through f - the information provided by bd represents all of the known information at this time.Despite good faith efforts to obtain additional information, the complainant / reporter was unable or unwilling to provide any further patient, product, or procedural details to bd.H3 other text : the device was not returned.
