The present invention relates to an endoluminal expandable implant with integrated sensors, in particular a stent. The stent body is at least largely enclosed on its inner or outer circumference by a flexible and stretchable film. A large number of electrodes, a thinned semiconductor chip with integrated electronics and conductor tracks for connecting the integrated electronics to the electrodes are arranged in the form of an array. The integrated electronics are designed to control the electrodes for recording impedance spectra in order to obtain spatially resolved impedance spectra over the surface of the film. Conductor tracks, which produce an electrical connection transverse to the longitudinal axis of the implant body on the film, are formed from an expandable material and / or run in a meandering shape. DOLLAR A The implant can be implanted and expanded in conventional form and provides proliferation parameters for safe risk stratification. |
