Abstract

A clinical intravital microscope with a heavy base; a motorized, mechanized or manual cantilever arm; and a microscope and camera portion at the distal end of the cantilever arm is provided. A method for observing and/or recording conditions such as blood flow, vessel characteristics, such as vessel density, tumor structure, tumor size and dimensions, is provided such that a physician is permitted to observe such information and characteristics in real-time.

First claim

What is claimed is:

1. An intravital microscope system for observing tissues of a human patient in real-time during a medical procedure, the system comprising:
a heavy base having one or more wheels for moving the base on a support surface;
an arm having a proximal and a distal end, the proximal end of the arm supported by the base, the arm extending horizontally from the base;
an intravital microscope having an eyepiece and an objective, the intravital microscope mounted on the arm, wherein the intravital microscope has a magnification between about 100× and 200×;
a video camera operatively associated with the intravital microscope;
a surface for supporting the human patient underneath the intravital microscope;
a processor for receiving and storing video images from the camera and for minimizing motion artifact; and,
wherein the base and the processor for minimizing motion artifact are configured and arranged to provide visualization of tumors in situ in the human patient in real time to generate dynamic data.

2. The system of claim 1 , wherein the microscope is configured and arranged for adjustment in an X and Y-axis.

3. The system of claim 1 , wherein the microscope is configured and arranged for vertical adjustment in a Z-axis.

4. The system of claim 1 , wherein the base further comprises a stabilizing element.

5. The system of claim 1 , wherein the patient supporting surface is disposed on a cart having a plurality of casters disposed thereon.

6. The system of claim 1 , further comprising a fluorescent illumination source.

7. The system of claim 6 , wherein the illumination source is epifluorescent.

8. The system of claim 1 , wherein the microscope is configured and arranged to be adjusted in a Z-axis relative to the arm.

9. The system of claim 1 , wherein a position of the arm is adjusted by a motorized system.

10. The system of claim 1 , wherein the arm is a cantilever.

11. The system of claim 1 , wherein the processor is disposed inside the base.

12. The system of claim 6 , wherein the illumination source is disposed inside the base.

13. The system of claim 1 , wherein the intravital microscope is mounted on a rotating turret.

14. A method for observing tissues of a human patient, the method comprising:
providing a heavy base having one or more wheels for moving the base on a support surface;
providing a stabilized arm such that motion artifact in the system is minimized;
providing an intravital microscope having an eyepiece and an objective, the intravital microscope mounted on the arm, the intravital microscope has a magnification between about 100× and 200×;
providing a video camera operatively associated with the intravital microscope;
providing a surface for supporting the human patient underneath the intravital microscope; and, using the intravital microscope to observe the tissues in real-time.

15. The method of claim 14 , further comprising providing visualization of human tumors in situ in real-time.

16. The method of claim 15 , further comprising observing and/or recording conditions selected from the group consisting of blood flow, vessel density, tumor structure, tumor size and tumor shape.

17. The method of claim 14 , further comprising a processor provided with software for minimizing motion artifact.
