Tetratherix, a medical device company backed by Xero founder Rod Drury, is set to float on the ASX this month, raising $25 million with an ambitious pitch to investors about the potential of its “medical Lego” product that helps the human body heal faster from injuries and surgery.

The company’s product has been in scientific development since 2011, and is built on the work of chief technical officer Ali Fathi, a biomolecular engineer who invented a new material that can be injected into wounds to help tissue and bones heal.
