Asthmatx Pulls FIling

Asthmatx Inc., a Mountain View, Calif.-based medical device developer that treats asthma, formally withdrew its IPO filing. It had announced last month that it would instead pursue “alternative strategic option,” while the withdrawal filing blames “current market conditions” for its decision. The company has raised venture funding from Boston Scientific Corp., HBM Partners, MedVenture Associates, Menlo Ventures, Montreux Equity Partners, Polaris Venture Partners and Vanguard Ventures.
