Abstract
The system and method for retaining a stent on an expandable stent delivery member involves applying a plastic material that will adhere or fuse to the expandable stent delivery member, and that is insoluble in blood, to one or both of the expandable stent delivery member and the stent, and mounting the stent over the expandable stent delivery member. The plastic material may be dissolved in a solvent to form a dispersion, and applied to the expandable stent delivery member and/or the stent, and is allowed to evaporate to deposit the plastic material. The plastic material also may be applied after the stent is mounted on the expandable stent delivery member, as a coating, or may be applied as knobs or fillets onto the expandable stent delivery member through the openings of the stent. Alternatively, a plastic material may be melted, applied as knobs or fillets onto the expandable stent delivery member through the openings of the stent, and allowed to cool, to retain the stent on the expandable stent delivery member. A system is also provided for applying a melted plastic material on an expandable stent delivery member for retaining a stent on the expandable stent delivery member.
