On 16th November 2021, The Aga Khan University received a patent for the “Pumping Heart Simulator". The patent lists Professor Saulat Fatimi, Dr. Mohammed Bin Pervez and Professor Charles Docherty as the inventors.
Most currently available simulators are unable to replicate the true mechanism of the heart, as they do not contain any fluid that would act as blood flowing through the device. The team invented a simulator using magnetic pumps, a fluid reservoir and a timing device that allows a fluid-filled cow's heart to beat and pump “blood" in a regular rhythm, thereby increasing its fidelity compared to other models.
His Highness the Aga Khan was extremely impressed when he was shown a prototype of the simulator in 2017 during CIME Karachi inauguration.
Prof Charles Docherty, Global Director of CIME said “Dr Saulat Fatmi is to be commended for his perseverance in pushing this through over many years. His resilience is admirable. The Pumping Heart Simulator will help teach our residents techniques in heart surgery in completely safe conditions".
