Pulse Medical Imaging Technology (Shanghai) Co. Ltd. has raised more than $100 million in a series C funding round to accelerate the R&D, clinical trials and commercialization of its products. “Pulse plans to use the funds to accelerate the commercialization of its fractional flow reserve (FFR) estimating systems,” Xiaojie Lin, marketing director of Pulse, told BioWorld. FFR is a method to measure blood pressure and flow within a coronary artery to check on the possibility that the stenosis impedes oxygen delivery to the heart muscle.
