Implantable medical device

摘要

An implantable medical device includes an actuator and/or sensor portion to be fixed to bodily tissue by means of a fixation mechanism, to act on the tissue and/or to detect a signal from the tissue, wherein at least one detector element, preferably a plurality of detector elements, adapted for detecting the close proximity of bodily tissue, is arranged on the actuator and/or sensor portion of the device, and an output of the or each detector element being connected or connectable to a detection signal evaluation unit for deriving a fixation state verification from detection signals provided by the or each detector element.

1. An implantable medical device comprising:
an actuator and/or sensor portion to be fixed to bodily tissue by means of a fixation mechanism, to act on the tissue and/or to detect a signal from the tissue; and a plurality of detector elements arranged on a distal end face and/or a distal circumferential portion of the actuator and/or sensor portion with predetermined spacings between each other, wherein at least one detector element is adapted for detecting close proximity of bodily tissue, wherein the at least one detector element generates detection signals transmitted to a detection signal evaluation unit for deriving a fixation state verification therefrom, and wherein the fixation state verification comprises a quantitative assessment of tissue contact or fixation quality.
