Endoluminales expandierbares Implantat mit integrierter Sensorik

摘要

The invention relates to an endoluminal expandable implant with integrated sensor system, especially a stent. The stent base (1) is at least substantially enclosed on its inner or outer diameter by a flexible and extensible film (2). In said film (2), a plurality of electrodes (4), a thinned semiconductor chip (6) with integrated electronics and conductor tracks (5) for linking the integrated electronics (6) with the electrodes (4) are arranged in the form of an array. The integrated electronics (6) is adapted to control the electrodes for registering impedance spectra in order to obtain spatially resolved impedance spectra across the surface of the film (2). Conductor tracks (5) that establish an electrical link at an angle to the longitudinal axis of the implant body (1) on the film (2) are produced from a flexible material and/or have a meandering structure. The inventive implant can be conventionally implanted and expanded and supplies proliferation parameters for the purpose of a reliable risk stratification.
