Patent ID: 10716658

Abstract:
An apparatus is configured to be implanted within a biological structure. The apparatus includes an annular retaining assembly and an occlusion member. The annular retaining assembly defines an annular opening and includes an outer ring and an inner ring. The outer and inner rings are disposed about a central axis. The outer ring also has an outer wall, an inner wall, and a bio-absorbable material. The inner ring defines an annular opening and is attached to the inner wall of the outer ring. The inner ring also includes a surface to promote tissue in-growth. The occlusion member extends from the annular retaining assembly toward the central axis. The occlusion member also includes a plurality of magnetics. The occlusion member is magnetically biased to a first position that substantially occludes the annular opening. The occlusion member is configured to elastically deform to a second position that substantially unblocks the annular opening.
