Abstract

A device for performing minimally invasive procedures in vivo has an endoscope body that carries at least one sensor or actuator and at least one magnetic element allowing the body to be freely navigated in the body of a patient by an extracorporeally applied magnetic field. the body carries at least one biochip sensor with capture molecules for detection of biological molecules in samples. A processing and analyzing unit in the body is connected to the biochip sensor for optical or electrical evaluation of the samples.

Claims

1-17. -17. (canceled)

18. A device for implementing a minimally-invasive procedure in vivo, comprising:

a device body configured to be freely movable inside the body of the patient;

a magnet carried by the device body allowing navigation of the device body inside the body of the patient by interaction with an extracorporeally generated magnetic field; and

at least one biochip sensor carried by said device body, said at least one biochip sensor comprising capture molecules that detect biological molecules in samples, and at least one preparation and analysis unit in said device body, in communication with said at least one biochip sensor, for optical or electrical evaluation of said sample captured by said biochip sensor.

19. A device as claimed in claim 18 comprising a retractable covering element that controls contact of said capture modules with said biological molecules.

20. A device as claimed in claim 19 comprising an external control unit in communication with said covering element that controls covering and uncovering of said capture molecules by said covering element.

21. A device as claimed in claim 19 comprising a magazine containing a plurality of biochip sensors each having capture molecules with identical characteristics, said covering element covering one end of said magazine.

22. A device as claimed in claim 19 comprising a magazine containing a plurality of biochip sensors each having capture molecules with different characteristics, said covering element covering one end of said magazine.

23. A device as claimed in claim 18 comprising a repository in said device body for storing chemical or biological substances.

24. A device as claimed in claim 23 comprising a discharge element in communication with said repository that allows discharge of the substance in said repository into the body of the patient.

25. A device as claimed in claim 24 comprising an external control unit that controls discharge of said substance from said repository into the body of the patient.

31. A device as claimed in claim 18 comprising a tissue extractor carried by said device body for interaction with tissue surrounding said device body in the body of the patient.

32. A device as claimed in claim 18 wherein said biochip sensor comprises capture molecules that allow a tissue analysis to be conducted on tissue in the body of the patient adjacent to the device body.

33. A device as claimed in claim 18 comprising a radiator, selected from the group consisting of laser radiators and thermal radiators, that emits an interventional radiation beam from the device body into the body of the patient.

34. A device as claimed in claim 18 comprising a fastening device that anchors the device body in tissue in the body of the patient.
