A blood pump comprising:
- an impeller assembly comprising a housing defined by a wall forming an interior and having an outer surface, the housing region comprising an expandable region, inlet apertures distal to the impeller assembly and outflow apertures proximal to the impeller assembly;
- at least one trough defined within the wall of the housing, the at least one trough comprising a shape, a width, a depth and a length, wherein the at least one trough does not extend into the interior of the housing,
- wherein the length of the at least one trough extends at least from the inlet apertures to the outflow apertures,
- wherein the at least one trough traverses the expandable region of the housing, and
- wherein at least one trough is configured to slidably receive and accommodate at least one electrical lead therein, and wherein the at least one electrical lead is adapted to slide within the at least one trough.
