Jhpiego and Momoscientific have developed a device called CryoPop, a 3-D printinted solution that uses dry ice to treat cervical pre-cancerous lesions.Out of Johns Hopkins Bioengineering and partnered with Maryland-based company Potomac Photonics for high resolution 3-D Printing. The medical device uses carbon dioxide tanks (the same kind used in by soda manufacturers). The dry ice is used for "cryoablation" of the lesions.
The CryoPop is in testing stage right now. They hope to create supply chains to distribute it throughout India and Africa.
