Milestone Scientific was incorporated in the State of Delaware in August 1989. Milestone Scientific has developed a proprietary, computer-controlled anesthetic delivery device, using The Wand ®, a single use disposable handpiece. The device is marketed in dentistry under the trademark CompuDent ® , and STA Single Tooth Anesthesia System ® and in medicine under the trademark CompuMed ® . CompuDent ® is suitable for all dental procedures that require local anesthetic. CompuMed ® is suitable for many medical procedures regularly performed in plastic surgery, hair restoration surgery, podiatry, colorectal surgery, dermatology, orthopedics, and many other disciplines. The dental devices are sold in the United States, Canada and in approximately 60 other countries. Certain medical devices have obtained CE mark approval and can be marketed and sold in most European countries. In June 2017, Milestone Scientific received 510 (k) marketing clearance from the U.S. Food and Drug Administration (FDA) on the CompuFlo ® Epidural Computer Controlled Anesthesia System. Through March 31, 2021 to date there have been twelve medical devices sold in the United States and limited amounts sold internationally. In December 2016, we received notification from the FDA that based upon the 510 (k)-application submitted for intra- articular injections, we did not adequately document that the device met the equivalency standard required for 510 (k) clearances. Following consultation with the FDA Office of Device Evaluation, we intended to file a new 510 (k) application for the device in 2019, however, due to financing constraints, a new 510 (k) application was not filed in 2019 or 2020. As of March 31, 2021, the Company has decided not to proceed with securing the FDA approval for the intra-articular instrument at this time. Milestone Medical's immediate focus is on marketing its epidural device throughout the United States and Europe. In April and June of 2020, the Company completed two Common Stock offerings generating net proceeds of approximately $4.6 million and $13.4 million, respectively (see Note 9 ). As of March 31, 2021, cash on hand was approximately $16.9 million, an increase of $2.7 million from December 31, 2020.
