  • Then an extension catheter is passed under the skin from the spine, around your torso to the abdomen and here the pump will be implanted.
  • The surgeon creates a pocket for the pump between the skin and muscle layers.
  • The extension catheter is attached to the pump.
  • Pump is correctly positioned under the skin and sutured to the thick fascia layer overlying the stomach muscles.
