## Abstract

A guiding probe for identifying a location within an anatomical region of a patient. The guiding probe can optionally: a graspable portion, an insertion portion and an emitter. The insertion portion can be coupled to the graspable portion. The insertion portion can have an elongated extent and a longitudinal axis. The insertion portion can include a flexible section and a bending section. The bending section can be positioned distal of the flexible section. The emitter can be coupled to a distal end portion of the insertion portion. The emitter can be configured for use within the anatomical region to emit a signal that can be detectable extracorporeally of the patient whereby the signal enables the location within the anatomical region to be identified extracorporeally for therapy to be applied.

## Claims

### Claim 1

A system for identifying a location within an anatomical region of a patient, the system comprising:
a display;
a guiding probe comprising: a graspable portion;
an insertion portion coupled to the graspable portion, the insertion portion having an elongated extent and a longitudinal axis, wherein the insertion portion includes a flexible section and a bending section, wherein the bending section is positioned distal of the flexible section; and
an emitter coupled to a distal end portion of the insertion portion, the emitter configured for use within the anatomical region to emit an ultrasonic sound signal, wherein the emitter is positioned at a distal tip of the insertion portion and is configured to emit the ultrasonic sound signal along a linear pathway from the distal tip, wherein the linear pathway extends from the distal tip through tissue of the patient including an epidermis; and
an ultrasound device extracorporeal of the patient and configured to detect the ultrasonic sound signal emitted within the anatomical region, whereby the ultrasonic sound signal when detected enables the location within the anatomical region to be identified extracorporeally and the ultrasound device positioned relative to the anatomic region;
an access needle having a shaft and a tip located at a distal end of the shaft, wherein the access needle is configured for a percutaneous access incision;
a processor configured to superimpose the ultrasonic sound signal as a line on an ultrasonic image displayed on the display,
wherein the line is displayed prior to the percutaneous access incision and the access needle is configured to be positioned using the displayed line,
wherein the ultrasound device includes one or more features for guiding the access needle during the percutaneous access incision.

### Claim 2 (depends on 1)

The system of claim 1, further comprising a signal generator configured to produce the ultrasonic sound signal, wherein the signal generator is coupled to the emitter via a pathway through the working channel.

### Claim 3 (depends on 1)

The system of claim 1, wherein the emitter is aligned with the longitudinal axis of the insertion portion and the guiding probe comprises an endoscope or is passed through a working channel of the endoscope.

### Claim 4 (depends on 1)

The system of claim 1, wherein the location within the anatomical region comprises a calyx of a kidney of the patient.

### Claim 5

A method of detecting an emitter within an anatomical region, the method comprising:
emitting an ultrasonic sound signal from a guiding probe that is positioned at a desired location within the anatomical region, wherein the anatomical region is a kidney;
detecting the ultrasonic sound signal extracorporeally;
superimposing the ultrasonic sound signal once detected as a line on an ultrasonic image and displaying the image on a display;
determining an extracorporeal location aligned with the desired location based upon a location of the detected extracorporeal ultrasonic sound signal and based upon a linear pathway for the ultrasonic sound signal from the desired location to the extracorporeal location;
and
accessing the desired location derived from the ultrasonic sound signal by puncturing through tissue from the extracorporeal location with an access needle guided by an ultrasonic probe based on the superimposed line.

### Claim 6 (depends on 5)

The method of claim 5, wherein the extracorporeal location comprises a position on a dermis.
