Welcome! Maguro Surgical Inc., a startup founded by urologists and scientists at Stanford University, has joined Fogarty Innovation’s Company Accelerator Program (CAP). The company is developing a first-of-its-kind magnetic retrieval device for endoscopic kidney stone fragment removal. Its groundbreaking technology—the MagStone System—deploys a magnetic coating to magnetize the individual stone fragments and then retrieves the fragments with a specialized wire with a magnetic tip.
Maguro Surgical is a graduate of Fogarty’s Invention Accelerator Program (IAP). During the program, IAP director John Morriss supported the team in developing a regulatory strategy, identifying suppliers, and testing their value proposition within the medical community. Reflecting on the experience, founder and CEO, Dr. Kunj Sheth, observed, “Our time in IAP helped shift our mindset from an academic endeavor to a commercially viable opportunity that can meaningfully improve patient care.”
At Fogarty, the Maguro team will focus on accelerating their preclinical work to reach first-in-human studies while also completing the close of their $4 million seed round. CAP is a six-month program for early-stage companies designed to help them achieve specific objectives within their broader business plan.
The Maguro Surgical team includes Daniel Massana Roquero, PhD, founder and director of R&D; Eric Johnson, principal engineer; Jon-Michael Knapp, PhD, chief of staff; Jessie Ge, MD, founder and consulting director of regulatory strategy; and Joseph Liao, MD, founder and consulting director of clinical affairs. Thomas Cutro, a masters student at Stanford School of Engineering, is also working with the team.
