A method of dissolving an obstruction in a blood vessel by the steps of preventing blood which is in contact with the obstruction from flowing through the vessel to locations downstream of the obstruction while permitting blood to flow through a passage past the obstruction; delivering to the obstruction a dissolution agent which works in conjunction with blood components to effect dissolution of the obstruction; analyzing the composition of fluid in contact with the obstruction; and at least periodically supplying blood to the fluid in contact with the obstruction, based on the result of the analyzing step.
