THE CONSTRAINT

Interventional devices keep getting smaller, and the distal assembly absorbs the difficulty. Machined micro-components typically need secondary deburring and edge finishing. Geometry a cutter can't reach becomes several parts plus a joining step. Each extra operation and each extra part adds a supplier, a tolerance, and a failure mode.

WHAT RIPL CHANGES

Single net-shape parts with internal geometry machining can't reach — burr-free as printed, 25 µm features, Ra 32 µin surfaces. The prototype process IS the production process: 1 to 100,000+ without requalification.

THE PROOF

Trio parts are being produced with repeatable quality at production scale for thrombectomy, delivery-system, and catheter-based cardiovascular programs — in 316L and 17-4PH.

Part classes

What we build for these platforms

Part class Why it's hard
Electrode components & sub-assemblies Electrode geometry at endovascular scale, where surfaces and edges are functional and there is little room for post-machining.
Guide & catheter tips Atraumatic external form with functional internal lumens — two geometries in one part machining does in two setups plus joining — plus texturing for reflowing and bonding polymer liners and jackets.
Articulating steerable assemblies Links and steering features for articulating distal sections — geometry that otherwise means laser-cut tube plus secondary joining.
Delivery-system components Sheath tips, capsule features, and structural micro-parts for TAVR/TMVR delivery — deployment systems increasingly depend on complex micro-mechanisms, each one a small part with functional features.
