Carlsbad’s Ra Medical Systems became a public company on Sept. 27, raising $66.3 million.
The company — which makes a laser catheter to treat a disease known to lead to amputations — issued 3.9 million shares at $17 a piece.
The $66.3 million total was higher than Ra Medical’s Sept. 17 paperwork expecting IPO proceeds of $50 million, but below the company indicating $86 million in a July regulatory filing.
Ra Medical is the second life sciences company to go public this year. This summer Crinetics Pharmaceuticals raised $102 million through an IPO, and earlier this week Equillium readied an IPO worth an estimated $86 million.
