Heat set and crimping process to optimize stent retention

摘要: A method for manufacturing a stent delivery catheter includes the step of crimping an expandable over inflatable balloon to create balloon-stent assembly. The assembly is then constrained by covering tube and shrink wrap which act together prevent expansion when pressurized. Next, In this configuration, heated permanently deform embedding into surface. result system in protrusions that are formed on surface inserted openings wall enhance retention forces acting between stent.
