Implantable Leads

Implantable Leads

The VNS Therapy® System uses a silicone-insulated lead to deliver the electrical signal from the pulse generator to the left vagus nerve. The latest generation of implantable lead is the PerenniaFLEX®.

  • The PerenniaFLEX®, Model 304 lead combines the flexible handling characteristics of earlier device models with 3.5-times greater durability.

The lead is bifurcated at one end, with two helical electrodes and an anchor tether, which are coiled around the vagus nerve. The other end has a single connector pin, which is tunneled subcutaneously to the chest pocket and inserted into the pulse generator. The lead is available in two sizes (2.0 mm and 3.0 mm) to accommodate different nerve sizes and ensure optimal fit.

Tunneler

Tunneler

The LivaNova® Tunneler, Model 402 is a single-use surgical tool used to subcutaneously tunnel the lead connector and body from the neck incision site to the generator in the chest pocket. It is compatible with all VNS Therapy Leads.

The Tunneler package contains four basic components: a stainless steel shaft, two fluorocarbon polymer sleeves (one small-diameter, one large-diameter), and a stainless steel bullet tip. If necessary, the Tunneler can be manually shaped (≤25 degrees) to help direct it through the body. 

Accessory Pack

Accessory Pack

The VNS Therapy Accessory Pack, Model 502 contains replacements for components of the lead and generator that may become unusable during routine surgery.

Each pack includes:

  • Hex screwdriver: used to adjust the generator setscrew(s) and to allow the escape of back pressure created by lead insertion. A hex screwdriver is also provided with the pulse generator.
  • Resistor assemblies (single and dual pin): used to perform the optional Generator Diagnostics (Pre-Implant Test) in cases of troubleshooting to verify that the generator is functioning properly, independent of the lead.
  • Four tie-downs: used to secure the lead to fascia during implantation and to help form the strain-relief bend and loop. Tie-downs are also supplied with the leads.
Patient Essentials Kit

Patient Essentials Kit

The Patient Essentials Kit is provided to the patient or caregiver after the VNS Therapy implant procedure. The kit contains:

  • Two VNS Therapy Magnets: can be used to provide on-demand stimulation as an attempt to abort or deintensify a seizure, temporarily inhibit stimulation, verify generator functioning, or reset the generator (in combination with the programming system).
  • Magnet accessories: one belt clip to wear the magnet pager-style and one wristband to wear the magnet watch-style
  • Patient Information cards: contains information about the VNS Therapy System that patients should carry with them at all times
  • Epilepsy Patient Manual
