  • Patent number: 10660647
    Abstract: A device for closing the left atrial appendage. The device has a flexible and elongate pulling element fixed to a flexible material layer connected fixed to a self-expanding stent. The closure implant can be drawn back into the lumen of a catheter by the pulling element, and in so doing the stent framework can be transferred into a compressed state. The device enables a monitored and controllable release of the closure implant.

  • Publication number: 20170020669
    Abstract: A catheter system comprising at least one catheter shaft 3, an anisotropic implant, in particular an implantable heart valve prosthesis 6, a control device for controlling and manipulating the catheter, and at least three electrodes 4, 5 and 11 in the distal region of the catheter, which are each conductively connected to an analysis unit by their own electrode lead. The catheter system can change between an insertion state and an orientation state, wherein this change is triggered by a manipulation of the control device. In the orientation state the three electrodes of the catheter system span a spatial angle that is different from that spanned in the insertion state.

  • Patent number: 9538942
    Abstract: The invention relates to a medical sensor system (10a/10c) for detecting a feature (12a/12c) in a human or animal body (14a/14c), including a signal pick-up unit (16a/16c), which can be implanted in the animal and/or human body (14a/14c), and a signal processing unit (18a/18c), which is spatially separated from the signal pick-up unit (16a/16c) and which includes a transmitter (20a/20c) and a receiver (22a/22c). The transmitter (20a/20c) emits an alternating magnetic field (24a/24c) to act on the signal pick-up unit (16a/16c), and the receiver (22a/22c) receives a response signal (26a/26c) of the signal pick-up unit (16a/16c), which is generated by the magnetic interaction of the alternating magnetic field (24a/24c) with the signal pick-up unit (16a/16c).
