Abstract

Device for introduction into a human or animal body, especially into an artery, specifically to be positioned in an aneurysmal sac in an artery between the wall of the artery and the wall of an endoprosthesis, comprising at least a pressure sensor and a transponder for wireless transmitting data available from the pressure sensor.

Claims

1. A method for using a miniaturized pressure sensor and transponder attached thereto, comprising introducing said miniaturized pressure sensor and transponder into an aneurysmal sac of a human or animal.

4. The method of claim 1, further comprising introducing said miniaturized pressure sensor and transponder into said aneurysmal sac with a catheter.

2. A method for measuring pressure in an aneurysmal sac of an artery of a human or animal body, comprising positioning a pressure sensor and a transponder attached to the pressure sensor in said aneurysmal sac, the transponder being arranged for wirelessly transmitting pressure data from the pressure sensor to detecting means outside said human or animal body.

3. The method according to claim 2, wherein said positioning comprises introducing the pressure sensor and transponder into said artery by means of a catheter and further comprising introducing an endoprosthesis into said artery in a position over the pressure sensor and transponder, thus enclosing the pressure sensor and transponder within said aneurysmal sac, between the wall of said artery and said endoprosthesis.
