Abstract:
1. A method of manufacturing a clip comprising: forming the precursor of a clip from a material comprising a superelastic alloy which has an austenitic state and a martensitic state, said precursor having a substantially annular body which is substantially planar and having a plurality of tines which extend radially outwardly from said body; inverting said precursor such that said tines extend radially inwardly and said precursor is in a generally planar configuration, a first tine of the plurality of tines extending toward a central axis of said body when in the substantially planar configuration and a second tine is in contact with the first tine, the central axis of the clip being perpendicular to a plane formed by the clip in the substantially planar configuration; heating said precursor in its inverted configuration to cause said alloy to become substantially austenitic; and quenching said heated precursor to form a clip which is substantially austenitic in the substantially planar configuration with at least two tines of the plurality of tines being in over-and-under, overlapping relationship in the substantially planar configuration.
