Percutaneous blood pump and introducer system

A kit, comprising:

• a pump housing with an impeller housed in the pump housing, the impeller being rotatable so as to cause blood to be drawn into and through the pump housing;
• a motor housing housing an electric motor for causing a rotational movement, the motor housing being distinct from the pump housing and spaced apart from the pump housing in a proximal direction;
• at least one flexible sheath extending between the motor housing and the pump housing and at least one flexible cable extending through the flexible sheath so as to transfer a rotational movement from the electric motor to the impeller, wherein the cable elements are coupled to each other via magnetic couplings;
• an inflow cannula extending distally from the pump housing, being fluidly coupled to the pump housing and providing a blood flow inlet at a distal end portion;
• an expandable outflow cannula, wherein a distal end of the outflow cannula is attached to the pump housing, the outflow cannula ex-tending proximally from the pump housing so as to be placed across a heart valve separating its distal end from its proximal end to create a one way fluid flow through the percutaneous blood pump;
• an expandable structure;
• a dilator;
• and
• an insertion sheath, wherein the insertion sheath has a tubular body that is configured to receive the expandable structure in a compressed form and the dilator inside the expandable structure to form a structure that is configured to be inserted as a unity into the patient's vessel, wherein the expandable structure is configured to be advanced out of the insertion sheath to allow the expandable structure to expand from the compressed form to an expanded form with increased diameter compared to the compressed form.
