Cardiovascular components frequently incorporate fine slots, narrow struts, thin sections, and closely spaced geometries that directly influence mechanical response and flow behavior. In devices exposed to pulsatile loading and continuous fluid contact, edge integrity and surface continuity are not secondary considerations; they influence fatigue performance, expansion symmetry, and long-term structural stability.
 

Conventional machining approaches rely on physical tool contact, which can introduce localized deformation or require secondary deburring in small-scale features. At miniature dimensions, even minor burr formation or edge rollover can alter effective geometry. Additional finishing steps introduce handling variability and increase process complexity in already regulated production workflows.
 

PECM removes material through controlled electrochemical dissolution rather than mechanical shear. Because the cathode does not contact the workpiece, delicate geometries can be formed with reduced risk of distortion. Fine features and internal transitions can be generated with controlled edge definition, supporting dimensional stability across complex parts.
 

As cardiovascular device designs trend toward smaller profiles and more intricate architectures, tolerance windows narrow and variability becomes less forgiving. Feature-to-feature consistency within a single device is essential, but part-to-part repeatability across validated production volumes is equally critical. Controlled cathode design and pulse parameter management allow PECM to support predictable material removal across cycles, enabling replication stability from development through scale-up.
 

In highly regulated manufacturing environments, process control and documentation are as important as geometry itself. PECM offers a stable and repeatable approach for producing miniaturized conductive components where precision, consistency, and production scalability must coexist.
