A method, apparatus, system and computer program product are provided which permit the functionality of a device to be adapted or otherwise altered without requiring the device to be completely reprogrammed. There is a biopsy means connected to the distal end of the actuator for cutting and collecting biopsy specimens and a removable distal storage and collection chamber connected to the elongated flexible member for receiving biopsy specimens cut and collected by the biopsy means. The UEs are subsequently sent downlink shared channel data in the shared channel time slots and sent non-downlink shared channel data to UEs in non-shared channel time slots. Additionally, the copolymers comprise an acidic moiety, derived from a polycarboxylic acid, and a biobeneficial moiety. In another embodiment, the seal is connected to the building block, and the seal at least partially encases a fluid sealant. The coating material is preferably aluminum oxide.
