1. A treatment system in which a fluid is withdrawn and then returned to a living body, the system comprising:
- outgoing and incoming fluid lines connected to the living body for transporting the fluid from the living body, through the treatment system, and back to the living body;
means for altering at least the density of the fluid as it flows through the system; and
a sensing unit within the system and comprising means for sensing at least the density of the fluid as the fluid flows through the sensing unit.

Abstract
A treatment system and method for treating a fluid withdrawn and then returned to a living body. The system includes outgoing and incoming fluid lines connected to the living body for transporting the fluid from the living body, through the treatment system, and back to the living body, a device for altering at least the density of the fluid as it flows through the system, and a sensing unit within the system and comprising a device for sensing the density of the fluid as the fluid flows through the sensing unit. The sensing device may be a micromachined Coriolis-based sensor also capable of sensing mass flow rate.

21. A method of treating a fluid of a living body, the method comprising the steps of:
-
withdrawing the fluid form the living body and into a treatment system;
altering at least the density of the fluid as it flows through the treatment system;
sensing at least the density of the fluid as it flows through the treatment system; and
thenreturning the fluid to the living body. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41)
