Robotic catheter for lung biopsy gets clearance

April 9, 2019 0 By FM

The US FDA cleared the Ion endoluminal system to enable minimally invasive biopsy in the peripheral lung, Intuitive Surgical said.

The Ion system uses an ultra-thin articulating robotic catheter that can move 180 degrees in all directions. The outer diameter of the catheter is 3.5 mm, which physicians can navigate through small and tortuous airways to reach nodules in any airway segment within the lung.

The Ion system’s flexible biopsy needle can also pass through very tight bends via Ion’s catheter to collect tissue in the peripheral lung. The catheter’s 2mm working channel can also accommodate other biopsy tools, such as biopsy forceps or cytology brushes, if necessary.

The system’s fibre optic shape sensor technology provides the physician with the precise location and shape information of the catheter throughout the navigation and biopsy process.

The Ion system easily integrate into existing lung nodule biopsy workflows, as well as existing imaging technology, including fluoroscopy, radial-endobronchial ultrasound, and cone-beam CT.
