Entrepix Medical

Entrepix Medical is a Phoenix, Arizona medical device company that spun out from semiconductor equipment company Entrepix to apply nano-polishing technology from chip manufacturing to surgical cutting instruments. The business has since rebranded around the Planatome name and commercializes ultra-smooth, low-trauma surgical blades and related instrument-surface modification services. Its core technology is a patented surface-modification process based on chemical mechanical planarization, designed to reduce tissue trauma, improve healing, and lower scarring relative to conventional blades. The company appears focused on commercial deployment rather than drug development and is expanding manufacturing and OEM partner activity in surgical instruments.
