Aurora Sensors

NDI manufactures the smallest electromagnetic (EM) tracking sensors at the lowest cost on the market today. These sensors have been designed for integration into third-party instruments where real-time tracking of tip position and instrument orientation is desired, with no line-of-sight restrictions. This capability allows OEMs to give their customers the ability to perform existing procedures more efficiently and with greater confidence.

Aurora sensors available for use include the following 5DOF and 6DOF options.

Five Degree-of-Freedom Sensors

These five degree-of-freedom (DOF) sensors are small, allowing for many integration options. The x-y-z position of the sensor and two of its orientations are reported, allowing surgical instruments to be displayed in the correct anatomical context in real-time.

Aurora 5DOF Sensor, 0.5 mm x 8 mm

Designed for integration into rigid or flexible tools where a small diameter is required. The sensor and lead wires are surrounded by a protective material which facilitates integration (e.g. into needles). The exceptional cost-performance ratio makes this sensor suitable for disposable applications.

Part Number: 610005 (Package of 5)
Dimensions: Sensor - 0.5 mm diameter x 8 mm length

Aurora 5DOF Sensor, 0.8 mm x 11 mm

The mechanical design of this sensor, being mounted to a small PCB, makes it more robust than our standard 5DOF sensor. This sensor is manufactured using mass-market technologies that provide the enhanced robustness of PCB design at an excellent cost-performance ratio, making it ideal for disposable applications.

Part Number: 610006 (Package of 5)
Dimensions: Sensor - 0.8 mm diameter x 11 mm length

Aurora Shielded and Isolated 5DOF Sensor, 0.9 x 12 mm

This sensor is designed for procedures near or inside the heart, in particular for integration into electrophysiology mapping and abalation catheters. The 5DOF sensor is encased in a protective tube, the lead wires are shielded to reduce interference from external electric fields, and the entire assembly is electrically isolated. The design also offers more mechanical robustness than other sensors and can withstand more than 500 bending cycles (at a bending radius of 7.5 mm and ± 180° bending angle).

Part Number: 610057 (Package of 2)
Dimensions: Sensor - 0.9 mm diameter x 12 mm length

Aurora Encapsulated 5DOF Sensor, 0.9 x 6 mm

This sensor is shorter in overall length than other sensors offered by NDI, to support integration into tools that require tighter bending performance. Its accuracy is slightly less than the longer 5DOF sensors. The sensor is encased in a protective tube and the assembly will withstand more than 100 bending cycles (at a bending radius of 7.5 mm and ± 180° bending angle).

Part Number: 610058 (Package of 5)
Dimensions: Sensor - 0.9 mm diameter x 6 mm length

Six Degree-of-Freedom Sensors

For applications that require tracking all six degrees of freedom (6DOF).

Aurora Mini 6DOF Sensor, 1.8 mm x 9 mm

A general purpose 6DOF sensor with a small outer diameter. This sensor is encased in a protective tube whose small diameter and short length allow for many integration possibilities. The exceptional cost-performance ratio makes this sensor suitable for disposable applications.

Part Number: 610029 (Package of 2)
Dimensions: Sensor - 1.8 mm diameter x 9 mm length

Aurora Micro 6DOF Sensor, 0.8 mm x 9 mm

This is the smallest 6DOF sensor offered by NDI and is provided in a user-friendly format. The sensor is supplied pre-soldered to a Redel connector containing a pre-programmed SROM device, making the sensor ready to use out-of-the-box. The sensor is encased in a protective tube and connected to a flexible micro-cable that can withstand more than 10,000 bending cycles (at a bending radius of 7.5 mm and ± 180° bending angle).

Part Number: 610059 (Sold individually)
Dimensions: Sensor - 0.8 mm diameter x 9 mm length

Accessories

Aurora Tool Cable Assembly

This assembly contains everything required to build an Aurora tool from an individual sensor. It comprises a 2.4 m tool cable attached to a Redel connector, with a built-in SROM device. All that is required is to solder the lead wires from one 6DOF sensor (or up to two 5DOF sensors) and program the SROM file. Package includes:

4 wires for sensors (1x6DOF or 2x5DOF)
4 additional wires for 3xGPIO signals (button press and/or LED functionality)
Redel connector with built-in SROM device
Straight-cut loose end

Part Number: 610003 (Sold individually)
Dimensions: 2.4 m in length
Sterilization: Can be sterilized via autoclave - will survive more than 20 cycles.
