Infiltration Device for Computer Assisted Navigation “I-Gun”

The Challenge

Epidural injection of local anaesthetics is one of the most commonly used interventions in managing chronic spinal pain. The transforaminal route to the lumbar epidural space for steroid injection has gained rapid and widespread acceptance for the treatment of lumbar and leg pain. Placing the hollow-needle for the infiltration process can often be challenging. Currently the positioning is provided by flouroscopic imaging and a contrast agent is used to pinpoint the location. The main difficulties in placing the hollow-needle arise while penetrating the surrounding tissue. The neurologic target may be missed if the hollow-needle bends.

Technology
The invention serves as a new hand-held device (“I-Gun”) that improves on the known disadvantages of the established systems. By combining the device with reference arrays, the physician may use the system for online 3D navigation of the hollow-needle during CT-imaging. An additional unique selling point is the reinforced conical bushing to prevent the hollow-needle from bending during the procedure.

The ergonomical shape of the I-Gun provides easy to use, reliable targeting and a safe procedure of the epidural injection, not only for the use with 3D navigation but also for conventional infiltration. Utility costs are minimized by the use of disposable syringes.

Commercial Opportunity
In-licensing or industrial cooperation for further development, CE-certification and commercialization of the technology.

Developmental Status
A prototype of the system has been successfully tested numerously in artificial anatomical models and cadavers at MHH.

Patent Situation
A utility model (20.2007.004.191.8) has been filed in June 2006.
