InVision System™

The FDA-approved InVision System provides needle guidance for open, percutaneous and laparoscopic biopsies and tumor ablations. IVS provides the surgeon or interventional radiologist with intuitive, real-time feedback on how to accurately place the needle before burning the tumor.

InVision System provides needle guidance for a
liver tumor ablation surgery.

A scientific study, presented at two surgical conferences (AHPBA and SAGES), has verified that surgeons improve their needle placement accuracy from 66% to 92% and reduce the time to “hit” a tumor by over 70% when using IVS. The Invision System includes the following components: The IVS Mobile Cart; The IVS Tracking Tracking Mounts; and The IVS Visualization Software.

InVision System enchances needle-based interventions

As shown in the first video below, InVision System improves needle-placement accuracy by rendering needle trajectory markers, the needle-ultrasound intersection point (purple square), and the ablation volume (red and orange "cage"). The ablation volume visual indicator shows the physician what tissue may be ablated, before the ablation takes place. This provides the physician with the confidence that the tumor is ablated, while minimizing damage to healthy tissue.

IVS also supports "out of plane" needle insertions, giving the surgeon or radiologist the flexibility to accurately place the biopsy/ablation probe at any angle relative to the ultrasound image.

The InVision System also displays an ablation volume guide (red and orange "cage" in the video below). The ablation volume visual guide shows the physician what tissue may be ablated, before the ablation takes place. This provides the physician with the confidence that the ablation needle/antenna is properly positioned, maximizing the destruction to the tumor while minimizing the damage to healthy tissue. As shown below, The ablation field is identified by the InVision system as the tumor is visualized with the use of Color Flow Doppler Imaging.

The Ablation Volume Guide provides a visual indication of the tissue to be
ablated. After ablation, the predicted ablation volume can be confirmed with
Doppler imagering. (Click "Right Arrow" button to play video clip).
