Abstract

Surgical devices with removable imaging capability and methods are disclosed. The imaging capability for the surgical devices are provided by a very small microendoscope having processor circuitry at the distal end for providing a video ready signal to a monitor. Because of the small size of the microendoscope, it can be used in conjunction with many surgical instruments which traditionally do not have integral imaging capability. In one application, the microendoscope may be used with Jackson grasping forceps. In another application, the microendoscope may be used with either a stent placement catheter or balloon catheter. In yet another application, the microendoscope may be used with an over-tube tissue separating, dissecting or fulgeration device. The application of the microendoscope with each of the above surgical instruments results in a unique method of performing a surgical task by providing imaging capability throughout all stages of introducing and removing the instruments from within the body of a patient.
