Second Sight Medical Products Inc. completed a reverse merger with Nano Precision Medical Inc. which leaves the controversial visual prosthetics company holding 23% of the new company, now called Vivani Medical Inc. The deal brings together two unlikely partners, with Nano Precision targeting development of miniaturized, subdermal drug implants for chronic diseases such as diabetes, while Second Sight has focused on bringing its Orion visual prosthetic device to market. The company now trades on the Nasdaq under the symbol VANI.
