Calyxo hoovers up $32M for vacuum-assisted device to remove kidney stone fragments

A common approach for the removal of large kidney stones has doctors insert a laser-tipped catheter into the organ to break up the stones into smaller pieces that are either plucked out one at a time with a basket or left to pass naturally through the urinary system. But that passage doesn’t always go according to plan, and fragments that don’t leave the kidney of their own accord can ultimately lead to pain, infection and further hospital procedures to remove them.
