Embodiment Construction

[0046] figure 1 Schematic cross-sectional view showing a double-walled pericardium with: the pericardium Pk forming the outer valve of the pericardium; the epicardium Ek forming the inner valve of the Mk); and the fine gap formed between the epicardium Ek and the pericardium Pk, i.e. the pericardial cavity or pericardial space Pkh, which serves as a fluid for the sliding membrane to fill.

[0047] figure 2 Shown in enlarged view according to figure 1 Region II of the pericardium Pk, epicardium Ek, and the pericardial space Pkh formed between the pericardium Pk and epicardium Ek and the myocardium Mk of the heart connected to the epicardium Ek. In order to implant the epicardial pacemaker electrode 4, the implantation catheter 1 is introduced percutaneously or transthoracically into the pericardium space Pkh after puncturing the pericardium Pk and moves along the pericardium space Pkh until it reaches the threshold for implantation. Optimal implantation site for epicardial...

Abstract

The invention relates to a device for the transcutaneous implantation of an epicardial pacemaker electrode (5), which is guided in a tubular, flexible external catheter (2) of an implantation catheter (1) that can be inserted into the gap of the pericardium (Pkh). According to the invention, the distal end portion of the electrode (4) is connected to a shape-variable element (6) for aligning, in particular for adjusting the implantation angle, and for stabilizing, in particular for laterally stabilizing the electrode (5).

Description

technical field [0001] The invention relates to a device for the percutaneous implantation of an epicardial pacemaker electrode in a tubular, flexible implant that can be introduced into the pericardial space. into the conduit. Background technique [0002] This implant catheter is introduced after piercing the pericardium (pericardium) into the narrow closed cavity formed between the lobes and the epicardium of the wall of the pericardium, the pericardial cavity or pericardial space in and forward to the site of implantation. At the implantation site, the epicardial pacemaker electrode is anchored in the epicardium-myocardium by means of a movable fixation mechanism (such as a screw), and the epicardial pacemaker electrode is made of an electrically insulating, with one or The electrode tubing consists of multiple non-insulated distal contacts. Electrical impulses output by a pacemaker connected to the proximal end of the electrode can be transmitted via the electrode fi...
