Founded in Philadelphia in 2022 as a spin-out of the Penn Center for Innovation, Ventru makes the DIVE Guide, a device designed to help neurosurgeons place external ventricular drains more safely and accurately. The company was founded by neurosurgeons Rachel Blue and Michael Spadola after their early training exposed the limitations of freehand intraventricular access, alongside medical-device commercial veteran Bryan Humbarger. In a 50-patient IRB-approved study, Ventru reports a 100% drain-placement rate with an average of one catheter pass.
