Abstract

An introducing device for introduction of a medical device into a body is described which has a distal region with a tip region for generating an opening in the skin, and a segment region which comprises at least two sections which, in a rigid state, are essentially rigidly connected at least to one another and to the distal region and which are movable relative to one another in a flexible state. Furthermore, a system is described in which a sensor is integrated into the device for introduction into a body.

Claims

1. An introducing device for introducing a medical device into a body, comprising:

a distal region which has a tip region for generating an opening in skin; and

,

a segment region having at least two sections, the at least two sections are essentially rigidly connected to at least one another and to the distal region in a rigid state for introducing the device and the at least two sections are movable relative to one another in a flexible state after the device has been introduced.

2. The device according to claim 1, wherein the rigid state is brought about by a forming element.

3. The device according to claim 1, wherein the device is hollow at least in a part of the distal region and/or at least in a part of the at least two sections.

4. The device according to claim 1, wherein the at least two sections are rigidly connected to one another and to the distal region by an immobilizing agent.

5. The device according to claim 4, wherein the immobilizing agent is dissolved or degraded in a body.

6. The device according to claim 1, wherein the at least two sections consist of essentially rigid segments.

7. The device according to claim 6, wherein the at least two segments are held together by a forming element.

8. The device according to claim 7, wherein the forming element is a pull wire.

9. The device according to claim 8, wherein the pull wire contracts when the temperature increases.

10. The device according to claims 8, wherein the pull wire is tightened by a pulling device.

11. The device according to claim 1, wherein the at least two sections are covered with a membrane.

12. The device according to claim 11, wherein the membrane is flexible.

13. The device according to claim 11, wherein the membrane contains an immobilizing agent.

14. A system for introducing a medical device into a body, comprising:

an introducing device comprising,

a distal region which has a tip region for generating an opening in the skin, and

a region which comprises at least two sections which, in a rigid state, are essentially rigidly connected at least to one another and which can be moved relative to one another in a flexible state; and

,

a medical device which is introduced into the body by the introducing device.

15. The system according to claim 14, wherein the medical device is a sensor.

16. The system according to claim 15, wherein the medical device contains at least one contact element for contacting the sensor.

17. The system according to claim 14, wherein a part of the at least two sections or the distal region is hollow at least in the tip region.

18. The system according to claim 15, wherein the sensor is integrated into the at least one hollow section of the at least two sections or of the distal region.

19. An introducing device for introducing a medical device into a body, comprising:

a distal region which has a tip region for generating an opening in the skin;

means for rigid state having a segment region having at least two sections, and the at least two sections are essentially rigidly connected to at least one another and to the distal region in for introducing a medical device; and

,

means for flexible state wherein the at least two sections are movable relative to one another after the medical device has been introduced.

20. A method for introducing a medical device into a body, comprising:

providing a distal region which has a tip region for generating an opening in the skin;

connecting rigidly at least two sections in a segment region, and the at least two sections are essentially rigidly connected to at least one another and to the distal region for introducing a medical device into a body; and

,

connecting flexibly the at least two sections in the segment region, and the at least two sections are movable relative to one another in a flexible state after the medical device has been introduced into the body.
