Calyxo (formerly Kalera Medical) has developed an innovative vacuum-assisted kidney stone retrieval device that enables rapid and complete removal of stone fragments. The device allows procedures that are faster and easier compared to the current standard of care.
Presently, stone removal is the most unpredictable, difficult part of ureteroscopy because current tools, i.e. baskets, have serious limitations.
Kidney stones affect about 10% of the population in industrialized countries and the number is growing. There is a 50% recurrence rate within five years. Calyxo’s instrument addresses a clear unmet medical need in a rapidly growing market segment.
