This is the first extremely smooth, surgically implantable, seam-free pulsatile blood pump to receive widespread clinical use. In its use in more than 250 patients, it has been responsible for saving numerous lives. When used as a bridge to transplant, the pump has a success rate greater than 90 percent. There has never been a device-failure-related fatality of any of these patients. A successful heart-assist pump could save an estimated fifteen thousand individuals annually.

This, the first Curtis vertical turbine built, was constructed by the General Electric Co. for the Newport & Fall River Street Railway Co. It operated in the Newport, R.I., generating station until June 1927. It was transferred to the Harding Street Station of the Indianapolis Power & Light Co. for display and later moved to the company's E.W. Stout Station.
