Overview
Planatome is a private, commercial-stage medical device company based in San Francisco, founded in 2021. It has developed a proprietary nano-polishing technology platform, adapted from semiconductor manufacturing (Chemical Mechanical Planarization), to create surgical blades with a surface roughness 1,000x smoother than conventional blades. Early clinical evidence and surgeon testimonials suggest significant advantages in accelerated wound healing, reduced scarring, and improved blade durability. The company has secured a $6 million capital investment and is expanding manufacturing operations in Arizona to scale its technology across multiple surgical instrument types.
Technology Platform
Semiconductor-inspired nano-polishing (Chemical Mechanical Planarization/CMP) applied to surgical instruments to create atomically smooth cutting edges that reduce tissue trauma.

Competitive Landscape
Planatome's primary competition is the entrenched standard of conventionally manufactured surgical blades from giants like Medtronic, Johnson & Johnson (Ethicon), and B. Braun. Its competitive edge is a demonstrable, physics-based improvement in edge smoothness and clinical outcome data. Niche competitors may exist in coated or diamond-edged blades, but the nano-polishing approach appears novel and defensible.
