Abstract

A tissue manipulation system includes Programmable Markers configured to be implanted on opposite sides of one or more portions of tissue within a patient's body, Markers communicating with one another to enable a determination of their relative positions and External Device receiving and transmitting signals to Markers containing information as to Marker's positions. Device is configured to: capture an image of the tissue portions with Markers; manipulate the image of the tissue portions in a virtual environment or a simulated environment to a desired restored orientation; determine desired positions Markers will have when the tissue portions are in the desired restored orientation; program implanted Markers with the desired orientations. Device generates an indicator signal upon Markers being manipulated into the desired orientations; and manipulate the tissue portions after Markers have been programmed, until an indicator signal is generated indicating that the desired restored orientation has been substantially achieved.

First claim

What is claimed is:

1. A system for performing tissue manipulation, comprising:
programmable markers configured to be implanted on opposite sides of one or more portions of tissue within a patient's body, the markers configured to communicate with one another to enable a determination of their relative positions; and
an external device configured to receive and transmit signals to the markers containing information as to the marker's positions, the external device further configured to:
capture an image of the tissue portions with the markers attached thereto;
manipulate the image of the tissue portions in one of a virtual environment and a simulated environment to a desired restored orientation;
determine desired positions the markers will have when the tissue portions are in the desired restored orientation;
program the implanted markers with the desired orientations; and
generate an indicator signal upon the markers being manipulated into the desired orientations.

2. The system according to claim 1 wherein the markers are passive markers.

3. The system according to claim 1 , wherein the communication during the procedure between the markers is continuously performed.

4. The system according to claim 1 , wherein the external device further includes a detection device configured to monitor the position of the markers.

5. The system according to claim 4 , wherein the detection device is configured to determine when the markers have arrived at the desired restored orientation.

6. The system according to claim 4 , wherein the detection device is configured to transmit the indicator signal.

7. The system according to claim 1 , wherein the tissue portions are fragments of bone, the system further comprising a fracture fixation device configured to be implanted to the bone fragments after the desired restored orientation has been achieved to maintain the desired restored orientation.

8. The system according to claim 1 , wherein the indicator signal is auditory.

9. The system according to claim 1 , wherein the image is captured using a method selected from the group consisting of x-ray, three dimensional x-ray, computed tomography, magnetic resonance imaging and ultrasound.

10. A system for performing bone fragment manipulation, comprising:
first and second programmable markers configured to be implanted on first and second fragments of bone, respectively, the first and second markers configured to communicate with one another to determine their position relative to one another; and
an external device configured to receive and transmit signals to the first and second markers containing information as to the positions of the first and second markers, the external device further configured to:
capture an image of the first and second bone fragments with the first and second markers attached thereto;
manipulate the image of the bone fragments in one of a virtual environment and a simulated environment to a desired restored orientation;
determine desired positions the first and second markers will have when the bone fragments are in the desired restored configuration; and
provide an indicator signal when the bone fragments have been manipulated such that the positions of the first and second markers corresponds to the desired positions of the first and second markers.

11. A system for performing bone fragment manipulation, comprising:
first and second programmable markers configured to be implanted and associated on opposite sides of a fragment of bone, wherein the markers are configured to communicate with one another to determine their positions relative to one another; and
an external device configured to receive from and transmit signals to the first and second markers, the signals containing information as to the positions of the first and second markers, the external device further configured to:
acquire an image of the bone fragments;
manipulate the image of the bone fragments in one of a virtual environment and a simulated environment until the bone fragments have achieved a desired restored configuration;
determine desired positions the first and second markers will have when the bone fragments are in the desired restored configuration;
program the external device with the desired positions of the first and second markers; and
generate an indicator signal when it is determined that the orientation of the first and second markers substantially corresponds with the desired positions of the first and second markers.
