Calyxo raises $40M Series F as CVAC kidney stone system treats 40,000 patients

Calyxo, a medical device company focused on kidney stone treatment, has closed a $40 million Series F financing round led by Ally Bridge Group and Janus Henderson Investors. Questa Capital, Avidity Partners and CRG also participated. The funding follows a milestone of 40,000 patients treated with Calyxo's CVAC System, an aspiration-based stone removal device. The system uses irrigation and vacuum aspiration to continuously clear stone fragments during procedures, enabling more complete stone clearance. Proceeds will support commercial expansion, clinical evidence generation through ongoing studies evaluating long-term outcomes, and continued innovation in kidney stone care. The CVAC System received FDA clearance in 2024 and is positioned as an all-in-one solution for minimally invasive kidney stone removal.

Study Presented At Aua Shows Superior Kidney Stone Clearance Rates For Sure Procedure Using Calyxo’S Cvac System Vs Standard Urs

PLEASANTON, Calif.--(BUSINESS WIRE)--Calyxo, Inc., a medical device company developing innovative solutions for patients with kidney stones, has announced that positive study results for its CVAC System were presented last week at the American Urological Association (AUA) Annual Meeting in San Antonio. The CVAC System, a revolutionary technology that is designed for complete kidney stone removal, was the focus of the prospective, randomized, multi-center ASPIRE study, which compared the safety and efficacy of steerable ureteroscopic renal evacuation (SURE) vs ureteroscopy (URS) with basketing. The 30-day results of the ASPIRE study were presented at the AUA Meeting by urologist Thomas Chi, MD of the University of California, San Francisco. In 101 patients, SURE demonstrated statistically superior stone clearance and significantly lower residual stone volume compared to standard URS. Unlike standard URS, the CVAC System achieved these results independent of baseline stone burden. Safety was comparable between groups

Calyxo Announces Fda Clearance For New, Redesigned Cvac System

PLEASANTON, Calif.--(BUSINESS WIRE)--Calyxo, Inc., a medical device company developing innovative solutions for patients with kidney stones, announced that it has received FDA clearance for its new, redesigned CVAC System, which enables a minimally invasive approach to kidney stone treatment. More than 50 procedures have already been completed by 12 urologists with the new CVAC System, yielding strong patient outcomes and consistently positive physician feedback. Clinical studies have shown that residual stone fragments are associated with a 20%-44% incidence of post-procedure problems, including pain, infection, emergency department visits, hospitalization and need for retreatment. Steerable ureteroscopic renal evacuation (SURE) using the original CVAC Aspiration System has been used to successfully treat more than 1,500 patients in the U.S., demonstrating that vacuum aspiration of stone fragments improves clinical outcomes, with 97% volumetric stone clearance and a high likelihood of avoiding the need for a secondary or more invasive procedure (according to clinical study data collected in patients treated with the device)
