Abstract

A system and method for indicating positioning of an internal anatomical feature is presented, including a display device external to a subject and a marking device positionable within the subject to identify one or more points of interest within a region of interest. The display device displays the one or more points of interest in response to at least one signal received from the marking device. The display device is applied to an outer surface of the subject. The display device may be a physical sheet of reactive material draped over the patient, a solution coated onto the subject or a monitor. The marking device may be a energy source, an ultraviolet source, an infrared source, a laser source or a visible light source inserted through an abdominal wall of the subject.

Claims

1. A system for indicating positioning of an internal anatomical feature, the system comprising:

a display device external to a subject; and

a marking device positionable within the subject to identify one or more points of interest within a first region of interest;

wherein the display device displays the one or more points of interest in response to at least one signal received from the marking device.

2. The system according to claim 1, wherein the display device is applied to an outer surface of the subject.

3. The system according to claim 2, wherein the display device is a physical sheet of reactive material draped over the subject.

4. The system according to claim 2, wherein the display device is a solution coated onto the subject.

5. The system according to claim 2, wherein the display device is a monitor.

6. The system according to claim 2, wherein the marking device is an energy source inserted through an abdominal wall of the subject.

7. The system according to claim 2, wherein the marking device includes at least one of an ultraviolet (UV) source, an infrared (IR) source, a laser source, and a visible light source inserted through an abdominal wall of the subject.

8. The system according to claim 2, wherein the display device is configured to collect the one or more points of interest identified by the marking device.

9. The system according to claim 2, wherein the one or more points of interest are signaled manually by a user.

10. The system according to claim 1, wherein a second display device is integrated into an implant, so as to allow a user to retrace marks on the outer surface of the first region of interest back onto the implant.

11. The system according to claim 1, wherein the marking device and/or display device are reusable.

12. A system for indicating positioning of an internal anatomical feature, the system comprising:

a marking device positionable within a subject to identify one or more points of interest defining a first region of interest, the marking device configured to record coordinates of the one or more points of interest; and

a display device external to the subject configured to display the one or more points of interest in response to at least one signal received from the marking device.

13. The system according to claim 12, wherein the at least one signal received from the marking device corresponds to a number of continuous or non-continuous points used for generating a map of the first region of interest.

14. The system according to claim 13, wherein the display device is a display unit including a monitor for displaying the map of the first region of interest.

15. The system according to claim 13, wherein the display device is a projector configured to project the map of the first region of interest onto an outer surface of the subject.

16. The system according to claim 12, wherein the marking device records one or more points corresponding to a perimeter of an implant, representing a second region of interest, defining a position of the implant relative to the first region of interest.

17. The system according to claim 12, wherein the marking device and/or display device are reusable.

18. A method for indicating positioning of an internal anatomical feature, the method comprising:

placing a first display device external to a subject;

positioning a marking device within the subject to identify one or more points of interest defining a first region of interest;

displaying the one or more points of interest on the first display device in response to at least one signal received from the marking device; and

retracing the one or more points of interest marked on the first display device with an energy source through the abdominal wall to display the first region of interest on a second display device integrated into an implant.

19. The method according to claim 18, wherein the first display device is one of a physical sheet of reactive material draped over the subject, a solution coated onto the subject, and a monitor.

20. The method according to claim 18, wherein the marking device includes at least one of a dual beam laser source, an ultraviolet (UV) source, an infrared (IR) source, a laser source, and a visible light source.
