Catheter system for the isolation of a segment of blood vessel

DETAILED DESCRIPTION In accordance with one aspect of the present invention, a catheter for isolating a segment of a blood vessel is provided.
It includes a guiding catheter having a proximal end and a distal end.
The guiding catheter has a major lumen and minor lumen arranged in parallel.
A first expandable latex balloon is attached circumferentially to an outside of the guiding catheter at the distal end thereof.
The first expandable latex balloon is connected via the minor lumen to a first inflation port arranged at the proximal end of the guiding catheter.
Fluid injected through the first inflation port expands the first expandable latex balloon.
A proximal assembly is connected to the major lumen at the proximal end of the guiding catheter.
The proximal assembly includes an aspiration port coupled to the major lumen for evacuating material from the major lumen.
A guidewire extends through the major lumen.
The guidewire includes a hollow tube having a proximal end and a distal end.
A solid segment of wire with a shapable core is attached to the distal end of the hollow tube forming a seal therewith.
A plug is selectively inserted into the proximal end of the hollow tube to form a seal therewith.
A second expandable latex balloon is circumferentially attached to the distal end of the hollow tube such that the second expandable latex balloon expands as fluid is received therein from a hole in the hollow tube.
A detachable manifold holds the proximal end of the hollow tube and the plug in alignment with one another when the plug is not inserted into the proximal end of the hollow tube.
The detachable manifold includes a second inflation port through which fluid is injected into the hollow tube thereby expanding the second expandable latex balloon.
In accordance with another aspect of the present invention, a catheter system for isolating a segment of a tubular organ is provided.
It includes a guiding catheter having proximal and distal ends.
The guiding catheter includes a major lumen and a first balloon that is selectively expandable
