Single Viva RF Generator

The Single Channel VIVA RF Generator is designed to create the predictable and consistent ablation zone by using the optimized ablation modes for various types of nodules. It also has convenient and useful functions including to the easy operation structure and smart User Interface to provide the exact information related to procedure details which is able to be translated to computer for recording patient treatment data.

Benefits of RFA for liver tumors;
Benefits of RFA for liver tumors;
  • RFA can be an effective treatment for primary liver cancer and for cancers that have spread to the live in select patients whose disease is unsuitable for surgical resection
  • In most studies, more than half of the liver tumors treated by RFA have not recurred.
  • Treatment-related serious compilations are infrequent and discomfort is minimal after RFA.
  • RFA may be used repeatedly to treat recurrent liver tumors is less expensive than other treatment options.
  • The percutaneous method of RFA is minimally invasive and does not require hospital admission.
  • RFA is a relatively quick procedure and recovery is rapid so that chemotherapy may be resumed almost immediately.
  • No surgical incision is needed – only a small nick less than 1 mm in the skin.

The benefits of RFA for thyroid nodules;
The benefits of RFA for thyroid nodules;
  • RFA is minimally invasive therapy to treat thyroid nodules without scars and does not require hospital admission.
  • Treatment-related serious compilations are infrequent and discomfort is minimal after RFA.
  • The patient recovers more quickly by putting them under local anesthesia, not general anesthesia.
  • Hospital admission is not necessary in case of RFA unlike Surgical operation which requires 5 days at least.
RFA electrodes
RFA electrodes
The VIVA RF electrode
The VIVA RF electrode

The VIVA RF electrode is single electrode which is designed to be used in multiple nodules. Traditional single electrodes make the fixed ablation volume, but it is able to make the varisized ablation volume by adjust an active tip.
It has a radio-paque marker which shows the position of electrode clearly on the fluoroscopic image.
Adjustable exposure length provides dynamic treatment options

  • Multiple nodules with different sizes
  • Decreasing pressure during coagulation by stepwise deployment
  • Saving normal tissue by making the varisized ablation volume

The star RF electrode (Fixed type)
The star RF electrode (Fixed type)

The star RF electrodes of fixed type are intended to be used in percutaneous, intraoperative and laparoscopic approaches in radiofrequency ablation procedures. Coolant circulation system of electrode maintains suitable impedance at the surface of electrode. It also prevents tissue adjacent to active tip from charring and helps to make an ideal spherical ablation zone.

The star RF electrode (Bipolar type)
The star RF electrode (Bipolar type)

The current created from RF generator flows only through the tissue which is between the two poles on an electrode. With bipolar delivery, no current flows through the rest of the body, so no grounding or return pad is needed. Hence, Bipolar series of star RF electrode are secure against skin burn.
The star RF electrodes of Bipolar type are effective for thyroid radiofrequency ablation.

Octopus RF electrodes
Octopus RF electrodes

Octopus RF electrodes are designed to activate three active tips with 200 watts simultaneously for creating a large ablation zone.
For radiofrequency ablation of multiple lesions, Octopus RF electrodes are able to be separated to three parts to create ablation zones respectively.
