Abstract

A catheter for isolating a region in a hollow organ of a mammal, having an elongate body designed to be inserted into a lumen of a mammal hollow organ and equipped with two balloons, the balloons being configured to be inflated to isolate an interior of the hollow organ therebetween; wherein a functional channel extending in the body has a functional opening provided in the body between the balloons; and wherein the functional channel is designed to allow a negative pressure to be produced in the isolated interior to take a biological fluid or biological gaseous medium therefrom or to allow a liquid or gaseous medium to be supplied to the isolated interior; and wherein another channel extending in the body is provided at opposite ends with an inlet and an outlet provided both in the body outside of the body part defined by the balloons.
