Miniaturized Sensors for IntraBody Navigation and Localization
Locating medical instruments in 3D space is a key requirement for image-guided procedures.
With that knowledge, clinicians can display an overlay of instrument coordinates onto pre-operative scans or real-time images. They also can guide tools to anatomical targets for intervention and delivery of therapeutic agents. Combined with imaging modalities, the tracker lets clinicians "see" through the patient for internal guidance and navigation.
Because targeting devices must function within the human body and be metal tolerant, there is an emerging need for new tracking technology. It must be accurate, unobtrusive and unaffected by line-of-sight or environmental issues.
microBIRD™ is a new Ascension tracker that meets these requirements.
Features include 6 DOF DC magnetic tracker with a sensor diameter of just 1.8 mm - small enough for insertion into 7 French catheters. It also offers conductive metal immunity. microBIRD provides precise, instantaneous tip localization of biomedical instruments.
Designed primarily for medical device manufacturers, microBIRD may not be incorporated into a customer's medical systems until all pertinent FDA and other regulatory approvals are attained.
