Precise Dissection

FMwand produces a precise, surface-only thermal effect with tactile control and minimal tissue drag, even through dense adhesions and tumors. The clean dissection results in clear margins for reliable pathology specimens.

Dissection Loops

Each FMwand handpiece incorporates a non-stick dissection loop, which is available in several shapes and sizes. Heat is  created uniformly around the circumference of the loop. Each loop activates instantly, cools in seconds, and can be rotated 180°.

Comparative incisions were made in pig liver at equal depth using both monopolar electrosurgery (left) and FMwand (right). Histology data were analyzed to measure the exact depth of incision (thick black line), and the area of collateral thermal injury (orange area). FMwand resulted in as little as 1/10th the amount of total thermal injury when compared to monopolar electrosurgery.

Minimal Thermal Injury

Imparts as little as 1/10th the thermal injury compared to monopolar electrosurgery, with as few as 80 microns (0.08 mm) of thermal spread in some tissue types.

The upper chart shows electromagnetic interference caused when using monopolar electrosurgery, and the lower chart shows no interference when using the FMwand during the same surgery

Electrical Silence

No electrical current passes through tissue. No grounding pad is used, and no spark, arcing, or stray current is produced. Surgeons using the FMwand report no generation of cardiac dysrhythmia, and no interference with electrophysiological monitoring, ultrasound imaging, cochlear implants, or CIEDs.
