The practicality and expense of maintaining patients on total artificial hearts (TAH) may be significantly impacted with the introduction of a new, investigational portable driver unit. The 13pound unit driver is intended to replace the previous 418pound driver, which will allow eligible patients to be discharged to wait for a transplant heart at home, rather than in a hospital.
