Abstract

An insertion device that allows gaining access to the left ventricle of the heart, via the tissue forming the wall of the right ventricle and via the ventricular septum, which includes a tubular shaft with a lumen extending there through, the shaft comprising distal, proximal and central sections, whereby the distal and proximal sections are disc-shaped extended thus forming each a double disc and whereby the central section links the distally placed double disc with the proximally placed double disc and whereby pressure valves are fixed inside the shaft preferably on its distal and proximal end.

Claims

1. Device for stimulation and/or defibrillation, comprising:

an insertion unit including a tubular shaft with a lumen extending there through, said shaft having distal, proximal and central sections, whereby the distal and proximal sections of the shaft are disc-shaped when extended, thus forming each a double disc, whereby the central section of the shaft links the distally placed double disc with the proximally placed double disc, and whereby a pressure valve is fixed inside the shaft on both the distal and proximal end sections thereof respectively; and

at least one stimulation electrode connected to a pacemaker, each electrode including a lead provided with a pole at a distal end thereof, whereby the insertion unit is conductive and is connected to an implantable cardiac defibrillator to form one of a defibrillation electrodes or to form an indifferent pole and whereby the lead of the stimulation electrode runs inside the shaft of the insertion unit.

2. Device according to claim 1, wherein the insertion unit consists of braided wires of memory material.

3. Device according to claim 1, wherein the insertion unit consists in part or in total of Silicon, Polyurethane, PTFE, Polyester, biocompatible fibers, Nitinol, Titanium or Stainless Steel.

4. Device according to claim 1, whereby an inner and/or an outer portion of the central section of the tubular shaft of the insertion unit is covered by a biocompatible synthetic material.

5. Device according to claim 1, whereby the central section of the tubular shaft of the insertion unit is coil shaped.

6. Device according to claim 1, whereby the tubular shaft of the insertion unit is longitudinally extended thus forming an extended shaft, the thus extended shaft comprising a further double disc with pressure valve at its proximal end.

7. Device according to claim 1, whereby the distal section of the shaft has only one disc having fixation hooks and whereby the central section of the tubular shaft is elastic.

8. Device according to claim 1, whereby the proximally placed disc of the double disc is connected to a port chamber by a port catheter.
