Abstract:
1. An apparatus for inserting an electrode into a myocardium of the heart, the apparatus comprising: an anchor including a tip portion configured to penetrate the myocardium in a first orientation and at least one rod-shaped portion configured to anchor against an outside surface of the heart in a second orientation; a tension element having a proximal end and a distal end, the distal end fastened to the anchor; and an electrode having an inner guide channel to accommodate the tension element and having a pole at an end adapted for stimulating the myocardium, the electrode and the tension element configured such that the electrode can be threaded over the proximal end of the tension element and slideably advanced over the tension element towards the anchor during implantation, the guide channel disposed at a connection point such that the tension element is attachable to the electrode and having a proximal opening adapted to allow the proximal end of the tension element to exit therethrough, the proximal opening being closed by a medical adhesive; wherein the anchor and the tension element are configured to couple to the electrode, thereby chronically retaining the distal end of the electrode in the heart after implantation.
