Conduit system for isolation of fluids in biological tissues
First Claim
1. A system for fluid isolation in a biological mass having at least one upstream channel and at least one downstream channel, comprising:
- a delivery conduit for administering a fluid to the biological mass, the delivery conduit having a length dimension suitable to be positioned from a first externally accessible channel of a patient adjacent to or into at least one upstream channel of the biological mass by way of a percutaneous transluminal route; and
a collection conduit for acquiring the administered fluid, the collection conduit having a length dimension suitable to be positioned from a second externally accessible channel of a patient adjacent to or into at least one downstream channel of the biological mass by way of a percutaneous transluminal route and having a collection seal having a dimension, in one configuration, to occlude the at least one downstream channel;
wherein the biological mass is selected from the group consisting of a heart, a portion of a heart, a kidney, a portion of a kidney, a stomach, a liver, and a brain.

Abstract
The invention presents is a fluid isolation system and method for confining fluid is a biological mass having at least one upstream channel and downstream channel. The system includes a delivery conduit for administering fluid to the biological mass and a collection conduit having and external seal and for retrieving the fluid. In the use of the system, the delivery conduit is positioned adjacent to or into the upstream channel and the collection conduit is inserted adjacent to or into the downstream channel. In one manner to confine the fluid, the seal on the collection catheter is activated to occlude outside fluid flow and divert the fluid into the lumen of the catheter.

16. A system comprising:
-
a delivery conduit having a length dimension suitable to be positioned by a percutaneous transluminal route from a first externally accessible channel of a patient adjacent to or into an upstream channel of a biological mass selected from the group consisting of a heart, a portion of a heart, a kidney, a portion of a kidney, a stomach, a liver, and a brain, and where the biological mass comprises at least one upstream channel and at least one downstream channel; a separate collection conduit having a dimension suitable to be positioned by a percutaneous transluminal route from a second externally accessible channel of a patient adjacent to or into a downstream channel of the biological mass, the separate collection conduit comprising a collection seal for occluding fluid flow by the collection seal; and a fluid to be administered to the biological mass through the delivery conduit, and reclaimed by the collection conduit, wherein the system achieves fluid isolation in the biological mass between the upstream channel and the downstream channel has at least one upstream channel and at least one downstream channel. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
