Dalent Medical was launched in 2017 by ENT surgeon Dr. Agustin Arrieta and engineer Peter Flores who saw the opportunity to develop an innovative, versatile and lower cost instrument to help surgeons treat patients with chronic sinusitis.

The Sinusleeve® Balloon is the world’s first balloon sinus dilation sleeve in the ENT field that offers a unique, universal design that provides surgeons the ability to use the same device on multiple sinuses and to use existing suction instruments and other rigid instruments to access the frontal, maxillary and sphenoid sinuses. The ability to use one device such as the Sinusleeve® balloon with a wide array of surgeon-familiar instruments, while also increasing functionality at a lower cost, is a true breakthrough for ENT doctors and their patients.


The Dalent Medical team is a diverse group of founders, investors and innovators committed to creating better solutions for physicians to help restore health and well-being to patients living with sinus-related conditions.
