DETAILED DESCRIPTION The object underlying the invention resides in creating an endocardial electrode arrangement of the type initially cited which achieves good emplacement within the heart and which nevertheless has a comparatively small volume.
In accordance with the invention this object is achieved in that, for the placement of the conductor, or of the electrode head, respectively, a loop or plurality of loops of soft thin material is provided which is mounted on the electrode head or on the electric insulation of the elongated electric conductor in proximity of the electrode head.
Loops of a soft, thin material, upon insertion of the electrode in a vein also having a very small diameter, lie closely against the electrode.
Thus, the insertion hardly meets with resistance.
In addition, the flexibility of the loop material permits local corrections of a random nature without the trabecula being damaged.
Moreover, connective tissue rapidly and readily grows into the loops, so that the electrode becomes well fixed on the heart wall.
An additional advantage of the loops lies in that, upon passage of the electrode through a vein, the loops become filled with blood coagulate.
The blood coagulate acts as an adhesive, so that the loops become securely adhesively attached to the heart wall, which leads to a particularly rapid growing into position of the electrode.
An additional advantage can be seen in that the inventive electrode, on account of its small diameter, can be employed in the case of a subclava punction.
In the case of a subclava punction, without a surgical incision, a catheter of a small diameter is punctured through the subclava.
The electrode is then inserted through the catheter into the vessel to the heart.
An advantageous further development of the invention is that the loops consist of a reabsorbable material.
What is achieved thereby is that the implanted electrode, at a later time, can be very readily removed, since the loops dissolve in time.
