Minnesota’s CSI raises $5M for arterial plaque-removing device
Cardiovascular Systems Inc. (CSI), based in New Brighton, Minnesota, has raised $5 million from the sale of debt, according to documents filed with the Securities and Exchange Commission. In 2008, CSI filed an initial public offering (IPO), hoping to raise $86.3 million to help expand sales of its Diamondback 360 device, which removes plaque from peripheral vessels in the pelvis or leg.
