Abstract:
1. A multi-component joint assembly incorporated into reconditioned end surfaces established between a first bone and at least one opposing second bone, said assembly comprising: a first component adapted to being anchored into the reconditioned end surface of the first bone and exhibiting a first exposed support surface; a second component is adapted to being anchored into a reconditioned end surface of at least one of the second bones and exhibiting a second exposed support surface; an intermediate component supported in at least one of eccentric or rotational articulating fashion between said first and second anchored components; and a plurality of micro debris entrapment chamber subassemblies incorporated into at least one of said components and communicating with at least one of said articulating surfaces for isolating and capturing debris resulting from joint wear, each of said entrapment chamber subassemblies further including a constricted perimeter location separating a joint zone entryway with an enlarged interior, a pair of rubberized membranes secured to perimeter edge locations of said entryway location being caused to be inwardly deflected in response to in-flow pressure forces resulting from normal joint articulation, resulting in pass through of said debris into said enlarged interiors.
