CENTIPACE Electrode Set is a sterile, single use Electrode set for temporary electrostimulation after open heart surgery, is intended to be implanted temporarily and must not remain in the patient’s body long term.

After most open-heart surgical procedures, it is typical for the surgeon to implant a temporary pacing lead in the epicardium or myocardial tissue of the atria or ventricles of the cardiac patient’s heart. The primary purpose of the temporary cardiac pacing wire / lead is to provide a means of monitoring and pacing the atria and ventricles.

CENTIPACE temporary cardiac pacing wire / lead consist of a conductive wire lead with one end stripped of insulation for some length, and crimped to a curved taper point suture needle for facilitating implantation in the myocardium. The other end of the insulated lead is attached to a straight cutting-edge Keith needle which is pushed through the thoracic cavity wall from the interior to the exterior. The Keith needle is equipped with a special break-off groove. The cutting part of the needle is broken off from the groove, and the stub forms an electrode plug which is connected to conventional pacing and monitoring equipment.

After the patient has stabilized, the pacing lead is withdrawn through the chest wall without opening up the thoracic cavity.

CENTIPACE temporary cardiac pacing wire / lead comprise of the following parts, each of the highest quality :

CONDUCTIVE LEAD :
Forty-nine or nineteen braided strands of 316-L implant grade stainless steel wire in 7X7 or 1×19 construction, insulated with a bio-compatible virgin PTFE/PE polymer. This provides a combination of excellent flexibility, strength, and conductivity and corrosion resistance. The highly flexible construction assists in atraumatic implantation and removal of the lead wire from the patient. The single layer PTFE insulation provides the smoothest coating used among cardiac pacing wires to minimize tissue trauma on insertion and removal.

CURVED SUTURE NEEDLE CRIMPED WITH THE ELECTRODE WIRE :
This is a 3/8 or ½ circle taper point / taper cutting needle crimped to the conductive lead exposed for 50 mm (or whatever length customer may specify) from the end of the curved needle to permit implantation of bare wire in the myocardium. This needle is siliconized to facilitate the insertion into the myocardial tissue.

BREAK-OFF KEITH NEEDLE:
The extra sharp Keith needle is also siliconized to minimize the force required for insertion through the chest wall. The break off groove provided in the shaft permits a clean and easy break, thereby eliminating the need to cut the needle with a wire-cutter.

The CENTIPACE Electrode Set comprises of a stainless steel braided wire ( AISI 316L), coated with a virgin PTFE/PE blue / white / orange polymer. One end of the wire is armed with a 1/2 circle or 3/8 circle round-bodied / Cut Taper atraumatic needle and the other end is armed with a straight needle (break-off). The straight break-off atraumatic needle also serves as the connection to the adapter cable and Electrode Set is sterilized with ethylene oxide.
