Most recently, Rogers led Silk Road Medical from an early-stage start-up to explosive growth and a successful IPO in 2019. Silk Road Medical currently has a market cap of approximately $2.0 billion. "I have been following HistoSonics' progress for years and believe that histotripsy offers a unique non-invasive solution capable of addressing a variety of significant unmet clinical needs. I look forward to being a part of the HistoSonics team, helping to ensure the Edison platform reaches its full potential to treat patients with significant disease across global markets and a broad number of care settings," commented Rogers.
