  • a grasping member having a proximal portion and a distal portion, said proximal portion comprising a body and a proximal end, and said distal portion comprising a plurality of fingers extending radially from a distal end of said body at a first angle, and collapsible therefrom to a second angle, said fingers having a distal portion configured to grasp an outer wall portion of said body vessel surrounding said opening when said fingers are extended at said first angle; and

    a locking member slidably received over a portion of said grasping member, the locking member movable along the fingers to collapse said fingers from said first angle to said second angle to cause said collapsed fingers to at least substantially close said vessel opening, said grasping member and said locking member being formed from a bioabsorbable composition,where at least one of said fingers of the grasping member and the locking member is structured and arranged to inhibit the locking member from axial movement in either a proximal direction or a distal direction after the fingers are collapsed.
