Working on a complex micro medical device design?
What if your material selection, tooling, molding, and packaging all happened under one roof — so you could move faster, make smarter decisions, and reduce costly iterations?
Our team of engineers collaborates with you early and often to improve your DFM, optimize unit cost, and answer critical questions throughout every step of the process.
Built for the complexity of medical micro devices
As a single-source manufacturer, MTD specializes in minimally invasive medical and healthtech devices—from overmolded electrodes to bioabsorbable implants—delivering tight tolerances and critical features required for validated production.
FDA registered. ISO 13485:2016 certified.
Overmolded Electrodes
The design required 0.004" (0.1016mm) walls around the electrodes. A custom tool was needed to compensate for slight electrode variability.
ENT Implant
This required minimal gate vestige to avoid skin irritation during use. Because EVA is a very soft material, we created a specialized tooling construction to control vestige at the gate location.
PEEK Biopsy Marker
The implant features 0.5mm-diameter holes. High-precision tooling enabled four side actions to converge, resulting in no visible parting lines.
Ablation Catheter Tip
This design features a 0.05mm-diameter hole with +/- 0.02mm ultra-tight tolerance. The custom tool was built primarily from carbide to withstand wear from the Tungsten filler.
Bioabsorbable Spiral Tack
To achieve the dead-sharp tip with no measurable vestige, unconventional tool construction methods.
Link Component
The design features a 0.004″ (0.10 mm) wall thickness surrounding 0.011″ (0.28 mm) diameter through-holes with exceptionally tight tolerances.
Vascular Tip
Diamond-turned inserts were required to achieve optical clarity in one area of the design.
