Abstract

It is provided a device for the transcutaneous implantation of an epicardial pacemaker electrode, which is arranged in a tubular, flexible implantation catheter insertable into the pericardial space. The distal end area of the electrode is connected to a shape-variable element for aligning the electrode, in particular for adjusting the implantation angle thereof, and for stabilizing, in particular laterally stabilizing, the electrode.

Claims

1. A device for transcutaneous implantation of an epicardial pacemaker electrode, which is arranged in a tubular, flexible implantation catheter insertable into a pericardial space, wherein a distal end area of the electrode is connected to a shape-variable element for aligning the electrode, in particular for adjusting an implantation angle thereof, and for stabilizing, in particular laterally stabilizing, the electrode;

and wherein the shape-variable element includes an aligning and stabilizing element, which receives the electrode and which has open or closed end-side rings and struts connecting the end-side rings, which struts, during advance of the implantation catheter from a puncture site to an implantation site, are disposed within an outer catheter and, after release of the aligning and stabilizing element, deploy to an implantation position.

2. The device as claimed in claim 1, wherein, in the implantation position, at least one central aligning strut aligns the electrode, and at least two support struts stabilize the alignment and position of the electrode.

3. The device as claimed in claim 1, wherein at least the struts of the aligning and stabilizing element that connect the end-side rings are made from a shape-memory material, in particular from nitinol, a spring material, in particular spring steel or plastic, or a pseudo-elastic material, in particular from nitinol.

4. The device as claimed in claim 1, wherein at least the struts of the aligning and stabilizing element that connect the end-side rings are made from a material with elastic restoring force.

5. The device as claimed in claim 1, wherein the electrode is arranged in a tubular, flexible inner catheter of the implantation catheter guided inside an outer catheter.

6. The device as claimed in claim 5, wherein an aligning and stabilizing element is arranged between the inner catheter and the outer catheter and is connected to the distal end of the inner catheter.

7. The device as claimed in claim 5, wherein the proximal end of the implantation catheter is connected to a device for sucking the distal end of the implantation catheter onto the epicardium.

8. The device as claimed in claim 5, wherein the open or closed end-side rings are open on at least one side and are configured to guide the aligning and stabilizing element past a mechanism for longitudinally slitting open the inner catheter and/or outer catheter.

9. The device as claimed in claim 1, wherein the shape-variable element arranged at the distal end of the electrode includes an inflatable balloon, which is connected via a supply line to the proximal end of the implantation catheter.
