Method and system for intrabody imaging

1. A device for imaging an anatomical site, the device comprising:

a first channel configured for traversing therethrough:

at least a portion of an ultrasound catheter, said ultrasound catheter having an ultrasound imager at an opened distal end thereof; and

a conduit, wherein a distal terminus of the conduit extends beyond the opened distal end;

a sheath having a second channel, said second channel configured for traversing of an optic imager therethrough and having a window at a distal end;

an adjustable chamber in communication with said ultrasound catheter, the adjustable chamber attached perpendicular to the first channel via a circumference of the adjustable chamber and at a distal most tip of the opened distal end of said device, the adjustable chamber covering at least the opened distal end of the device and configured for enclosing said ultrasound imager, said adjustable chamber being configured for being adjusted by a wave conductive medium introduced thereto via said conduit; and

a third channel mounted on an outer surface of the device and configured for traversing of an endoscopic tool therethrough.

2. The device of claim 1 , wherein the optic imager is an optic fiber.

3. The device of claim 1 , wherein the window is constructed of a clear, rigid material through which the optic imager is able to capture video images.

4. The device of claim 3 , wherein the clear, rigid material is selected from glass, plexiglass, and polyester.

5. The device of claim 1 , further comprising:

a deflector mounted at said opened distal end and configured to deflect said third channel in a fixed direction from a longitudinal axis of said first channel by an angle that causes said endoscopic tool to divert toward a targeted anatomical site without changing an orientation of said ultrasound catheter and said ultrasound imager in said adjustable chamber of said device when said endoscopic tool is extended out of said opened distal end beyond a range of said adjustable chamber towards the targeted anatomical site.

6. The device of claim 1 , wherein said device is configured for insertion into a body lumen in proximity to a targeted anatomical site, and said adjustable chamber is configured for being stretched to increase wave conductivity in a space between said targeted anatomical site and said ultrasound imager.

7. The device of claim 6 , wherein said wave conductivity is increased by reducing the space between an outer surface of said adjustable chamber and at least one inner wall of said body lumen.

8. The device of claim 6 , wherein said ultrasound imager comprises at least one ultrasound transducer and said wave conductivity is an ultrasonic conductivity.

9. The device of claim 1 , wherein said adjustable chamber and said device are integrally formed.

10. The device of claim 1 , further comprising a mechanism configured for reducing an amount of gas in said adjustable chamber.

11. The device of claim 1 , wherein the first channel is defined by a wall having a constant width at said opened distal end.
