## Abstract

A method includes providing a lithotripsic device configured to break a stone into one or more fragments in a body lumen and an endoscope which is configured to obtain a captured image in the body lumen. The method further includes processing the captured image and creating a processed image for display on a monitor, and processing and displaying a track of a movement of at least one of the stone or the one or more fragments.

## Claims

### Claim 1

A method, comprising:
providing a lithotripsic device comprising a laser configured to break a stone into one or more fragments in a body lumen;
configuring an endoscope to obtain a captured image in the body lumen;
processing the captured image and creating a processed image for display on a monitor; and
processing and displaying a track of a movement of at least one of the stone or the one or more fragments.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the processed image comprises an image of a final location of the one or more fragments, the method further comprising providing an indication of the final location on the processed image.

### Claim 3 (depends on 1)

The method according to claim 1, wherein a final location of the at least one of the stone or the one or more fragments is outside a field of view of the endoscope, the method further comprising providing an indication of a direction of the final location.

### Claim 4 (depends on 1)

The method according to claim 1, and comprising measuring a dimension of the stone and a corresponding dimension of the one or more fragments, and providing a comparison of the corresponding dimension to the dimension.

### Claim 5 (depends on 1)

The method according to claim 1, and comprising evaluating a cardinality of the fragments.

### Claim 6 (depends on 1)

The method according to claim 1, and comprising providing a comparison of a total size of the fragments to a size of the stone.

### Claim 7 (depends on 1)

The method according to claim 1, and comprising capturing the image at a frame rate, and increasing the frame at least during activation of the lithotripsic device.

### Claim 8 (depends on 7)

The method according to claim 7, and comprising displaying the captured image at a lower frame rate than the increased frame rate on the monitor.

### Claim 9 (depends on 1)

The method according to claim 1, and comprising determining a location of one of the one or more fragments from the captured image, and changing a direction of view of the endoscope in response to the location so as to track the one of the one or more fragments.
