Abstract
An implant (98) having an implant filter assembly (92) is disclosed. This implant filter housing (92) is disposed within a passageway (102) of an implant housing (100). One configuration for the implant filter assembly (92) is in the form of a filter assembly (26). The filter assembly (26) includes a LIGA filter element (22) that is disposed between adjacent ends of a first inner housing (34) and a second inner housing (38). These housings (34, 38) are at least partially disposed within an outer housing (30) such that the outer housing (30) is disposed about the LIGA filter element (22). Preferably, at least the outer housing (30) is more rigid than the implant housing (100), at least at a time when the implant (98) is installed in the target biological material.
