Instead of a totally artificial heart which replaces the entire heart, an lvad is a much smaller pump that boosts the pumping ability of the left ventricle (the main pumping chamber). This has many technical advantages over a totally artificial heart.

It is a device that assist the lv. It does so by relieving "work" or stress on the lv. The principle is for the blood going to the lv be diverted to a "pump" which then functions as a substitute lv to pump the blood back to circulate. Your natural lv then gets a rest as a substitute pump is doing the "work". The pump can be in or outside your body.

It is a device that propels blood thus taking over the function of the weak and failing left lower heart chamber. It is typically implanted in patients with severe class 4 heart failure who would otherwise have little mobility or not survive due to the failing heart.
