Radio Frequency Ablation (RFA) is a new technique for treating tumors localized to certain organs such as the liver, kidney and lungs. With this technique, relatively small probes are placed into the tumor and radio frequency (RF) energy deposited. The RF energy causes the tissue around the tip of the probe to heat up to a temperature where cells break apart and die. Since RF kills both tumor and non-tumor cells, the goal is to place the probes so that they destroy all of the tumor plus an adequate "rim" of non-tumorous tissue around it.
During a
Radio Frequency Ablation procedure, the doctor places a slender probe directly
into the tumor. Arrays of several small, curved electrodes are deployed from
the end of the probe into the tissue. The generator is turned on and target
temperatures are entered. The radio frequency energy flows through the
electrodes, causing ionic agitation, and therefore friction, in the nearby
tissue. This friction creates heat which kills and destroys the tumor.
There are several different ways that a RFA procedure may be performed
which your doctor will help you decide depending on the type and size of
tumors, their number and location, the severity of the disease, and your
general health. One option is a percutaneous approach. With this approach, a
needle-sized electrode is passed directly through the skin and guided into
place. This requires only light sedation and you
can go home
the same day. Another option is a laparoscopic approach. With this approach,
several tiny incisions are made, allowing the insertion of the RFA and imaging
probes. This requires general anesthesia and you can usually go home the next
day. A third option is open surgery. With this approach the RFA can be used
during open surgery, allowing the doctor to view the tumor before and during
treatment. This requires general anesthesia and a slightly longer recovery.
- Reduction of the size or elimination of tumors
- In an out patient setting it requires only local anesthesia
- Minimally invasive - usually done on an out-patient basis
- Highly effective - can be used on tumors up to 7 cm in size.
- Can be used repeatedly for recurring or new tumors
- Few complications or side effects
Risks:
- Low-grade fevers for a few days following the procedure
- Very low risk of skin burns, bleeding, fluid accumulation, injury to adjacent structures and infection
RFA -Vantage Mobile- and
the RITA System
A Minimally Invasive Treatment Option
for Liver and Bone Lesions
Our patented electrosurgical delivery method, known as The RITA System uses
deployable radiofrequency (RFA) electrode arrays to raise the temperature of
cells above 45 to 50°C and cause cellular death.
More Options. More Control.
Used by surgical oncologists, hepatobiliary surgeons, liver transplant
surgeons, laparoscopists and interventional radiologists, the RITA System
offers patients with unresectable liver lesions an effective treatment option
with few side effects or complications. The RITA System is also cleared for
use as a pain relief method for patients with metastatic bone lesions.
StarBurst Electrosurgical Devices
Our disposable
devices are monopolar electrodes capable of monitoring direct tissue
temperatures and impedance from the ablation site. Using automatic temperature
control, the devices are able to effectively destroy the entire targeted area.
