Patent abstract
Embodiments of the invention provide a left ventricular assist device (LVAD) cannula that includes multiple independent sensors may help decrease the incidence of ventricular collapse and provide automatic speed control. A cannula may include two or more independent sensors. One sensor may measure ventricular pressure, while another may measure ventricular volume and/or ventricular wall location. With this information an automatic control system may be configured to adjust pump speed to minimize the likelihood of ventricular collapse and maximize LVAD flow in response to physiologic demand. Typically the volume sensors are conductance sensors. Further embodiments provide LVADs that are powered by RF energy.
