1. A ventricular assist device, comprising:
a cannula defining a lumen and including a first end and a second end, the second end of the cannula including a tip that defines an opening for outflow of blood;
a pump operably coupled to the first end of the cannula and having an inlet in fluid communication with the opening;
a pump anchor operably coupled to the pump, the pump anchor having a retracted position and a deployed position; and
a tip anchor operably coupled to the second end of the cannula proximate the tip;
wherein the pump anchor and the tip anchor each include an attachment portion and a plurality of extensions extending from the attachment portion, and wherein the pump anchor and the tip anchor are coupled to the pump and the second end of the cannula, respectively, at the respective attachment portions;
wherein the plurality of extensions of the pump anchor define an interconnected net disposed around the pump such that the inlet of the pump in use intakes the blood in circulation upstream ahead of the blood passing through apertures of the interconnected net; and
wherein the pump anchor includes a plurality of eyelets and a wire disposed through the plurality of eyelets and configured to be drawn to draw the plurality of eyelets closer to one another.
