Ventaris Surgical is a privately held med-tech firm focused on improving kidney stone surgery through a novel ureteroscopic system that minimizes friction in the procedure and helps surgeons attain consistent, complete stone clearance. The company asserts that current instruments make it difficult to reliably remove all stones because of anatomical variation, stone burden, workflow constraints, and surgeon fatigue. By redesigning the toolset, Ventaris intends to boost surgical outcomes while easing surgeon workload. Headquartered in San Carlos, California, the startup is still in the clinical development stage and has not disclosed commercial revenues or user metrics. It plans to use newly raised capital to advance clinical studies and achieve key regulatory and commercial milestones. Board expansion accompanies the financing, adding Varun Gupta (Longitude Capital) and Justin Klein (Vensana Capital) alongside independent director Amir Abolfathi.
