A start-up operating out of MIT in Cambridge, Mass., called Portal Instruments has developed a needleless injection system.
The device, called PRIME, delivers medication into the bloodstream in a high-pressure stream that travels at Mach 0.7 – the speed of a jet. The makers signed a commercial deal in December 2017, and the device is expected to be available soon.
