Occlusion perfusion catheter

A catheter comprising:

• a) a catheter shaft having a longitudinal axis, a distal end having a shaft distal tip, and a proximal end;
• b) a first balloon positioned on the shaft proximal to the shaft distal tip, a second balloon positioned on the shaft proximal to the first balloon, and a third balloon positioned on the shaft proximal to the second balloon, wherein said second balloon is constructed of a non-compliant material;
• c) a first inflation lumen in communication with the first and third balloons, wherein said first inflation lumen is further in communication with a first balloon inflation port formed on the proximal end of the catheter shaft;
• d) a second inflation lumen in communication with the second balloon, wherein said second inflation lumen is further in communication with a second balloon inflation port formed on the proximal end of the catheter shaft;
• e) an agent delivery lumen, and an agent delivery segment positioned on the shaft between the second and third balloons and having one agent delivery segment orifice formed therein, wherein the agent delivery lumen is in communication with the agent delivery segment orifice and an agent delivery port formed on the proximal end of the catheter shaft;
• f) an aspiration lumen, and an aspiration segment positioned on the shaft between the first and second balloons and having one aspiration segment orifice formed therein, wherein the aspiration lumen is in communication with the aspiration segment orifice and an aspiration port formed on the proximal end of the catheter shaft, said aspiration port optionally further comprising a valve in communication with the aspiration port;
• g) a guidewire lumen formed within the shaft and in communication with an opening formed in a proximal end of the catheter and an opening formed in a distal end of the catheter;
• h) a first pressure-sensing means having proximal and distal ends and a length therebetween extending through said agent delivery lumen, wherein said first pressure-sensing means proximal end is in communication with a connector formed on the proximal end of the catheter shaft and said first pressure-sensing means distal end is at the agent delivery segment orifice or within the agent delivery lumen;
• and
• i) a second pressure-sensing means having proximal and distal ends and a length therebetween, wherein said second pressure-sensing means proximal end is in communication with the connector formed on the proximal end of the catheter shaft and said second pressure-sensing means distal end is located within the agent delivery lumen,
• wherein said agent delivery segment orifice and said aspiration segment orifice lie on opposite sides of said longitudinal axis.

• e) an aspiration segment positioned on the shaft between the first and second balloons and having one aspiration segment orifice formed therein;
• f) a visualization means lumen in communication with a visualization means slot;
• g) a visualization means extending through said visualization means lumen at least to said visualization means slot, wherein said visualization means may turn about the longitudinal axis via torque applied to said visualization means;
• and
• h) a guidewire lumen formed within the shaft and in communication with:
• an opening formed in a proximal end of the catheter;
• and an opening formed in a distal end of the catheter,
• wherein said agent delivery segment orifice and said aspiration segment orifice lie on opposite sides of said longitudinal axis.
