Ra Medical Systems, Inc. (the “Company”) was formed in September 4, 2002, in the state of California and reincorporated in Delaware on July 14, 2018. The Company is a medical device company commercializing advanced excimer lasers for use in the treatment of dermatological and vascular diseases. The Company develops, manufactures and markets medical devices targeting the dermatology and vascular specialties. The Company’s product development centers around proprietary applications of its advance excimer laser technology for use as a tool in the treatment of psoriasis, vitiligo, atopic dermatitis, leukoderma, and peripheral artery disease (“PAD”).
