Claim 0:
1. A catheter pump system comprising:
a catheter for insertion into a patient into a position extending through an aorta of the patient such that a distal end portion of the catheter can be located near or extend through an aortic valve of the patient, the catheter having an inlet port at or near a distal end and an outlet port proximally of the inlet port and communicating with the inlet port via a blood flow channel;
a pump having a fluid displacement member in the blood flow channel that provides communication between the inlet port and the outlet port;
a motor coupled to the pump for driving the pump;
a motor controller for controlling motor speed, the motor controller having a pressure sensing port for connection to a control pressure source, the motor controller being arranged for causing motor speed to be increased in response to a reduction of pressure applied to the pressure sensing port and for causing motor speed to be reduced in response to an increase of pressure applied to the pressure sensing port.
