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.

Smart tip LVAD inlet cannula

A totally implantable artificial heart that utilizes a fluid displaced from the left blood pump to power the right blood pump. The left blood pump is a sac-type pump powered by an electric motor that, when contracting and expanding, displaces a volume of fluid in a fluid chamber within the left pump housing. The fluid is displaced through a fluid line connecting the right blood pump, which is a pneumatically operated sac-type or rotary-type pump. The artificial heart permits spatial separation of the left and right blood pumps within the chest of the patient for ease in implantation.
