Devices, systems and methods for treating tissue regions of the body
First Claim
1. A catheter assembly comprising a catheter tube, an operative element carried at one end of the catheter tube, the operative element including at least two fluid-conveying ports, a manifold body carried within the catheter tube, the manifold body including a single main fluid junction coupled to a fluid source or a fluid destination external to the catheter tube, multiple branch fluid junctions each individually coupled to one of the fluid-conveying ports on the operative element, and a fluid circuit formed within the manifold body to channel fluid between the single main fluid junction and the multiple branch fluid junctions.

6. A method of handling fluid flow to or from an operative element carried by a catheter tube comprising the steps of
providing a manifold body sized to fit within the catheter tube, the manifold body including a single main fluid junction, multiple branch fluid junctions, and a fluid circuit formed within the manifold body to channel fluid flow between the single main fluid junction and the multiple branch fluid junctions, coupling the single main fluid junction to a fluid source or a fluid destination external to the catheter tube, coupling each of the multiple branch fluid junctions individually to a fluid-conveying port on the operative element, and mounting the manifold within the catheter tube.
