Abstract: A ventricular assist device includes a pump including a housing having an inlet, an outlet and a moveable element disposed in the housing for urging blood from the inlet to the outlet. An outflow cannula having a proximal end attached to the pump housing, a distal end remote from the pump housing, an interior bore in communication with the outlet of the pump housing, and at least one outlet aperture communicating with the interior bore remote from the pump housing is included. At least one sensor mounted to the outflow cannula and configured to detect a parameter of blood flowing at least one from the group consisting of through the outflow cannula and about an exterior of the outflow cannula is included.

Abstract: A ventricular assist device for intraventricular placement inside a heart of a mammalian subject includes a pump including a housing having an inlet end, an inlet at the inlet end, and an outlet. The pump further includes a moveable element disposed in the pump housing for pumping blood from the inlet to the outlet. A base member is included as well as a spacer member connected to the pump housing and the base member. The base member is positioned a distance from the inlet end of the pump housing to define a gap therebetween. One or more sensor elements are mounted to at least one from the group consisting of the base member and the housing, the one or more sensor elements being configured to measure one or more blood parameters prevailing within the gap during operation of the pump.
