Our mission is driving tissue-identifying bio-impedance needles to
1) Start the transformation of lumbar puncture towards impedance augmented
2) Introduce tissue-identifying biopsy tools for tumors including cancerHow It Works
Injeq has developed bioimpedance based tissue identifying products for medical use.
Tissue identifying Injeq IQ-Needle feels like a high quality spinal needle. Injeq IQ-Needle includes a unique electrode that allows bioimpedance measurement of the tissue in contact with the tip of the needle.
A proprietary low energy measurement signal allows Injeq BZ-301 to analyze the changes in signal caused by the tissue contact, and calculate the impedance in multiple frequency points. The calculation is compared against a statistical tissue model in real-time and a simple text for tissue type is shown to user or an audio alert is made. The measurement is continuous and repeated hundreds of times every second.
In practice the user will enjoy real-time tissue identification in his/her application.Key attributes of Injeq technology portfolio:
Real-Time Bio-Impedance Spectroscopy
- Medical grade real-time impedance measurement conforming to IEC 60601 and IEC 62304
- Proven real-time tissue identification (in vivo clinical studies)
- Bi-polar electrode design for space constrained needle tips
- Statistical tissue models based on proprietary tissue database
- Parametric configuration of analyzer which allows developing new applications in rapid manner
This image illustrates impedance frequency dependency over time in a continuous measurement session during a spinal puncture. Blue tissue in the end of the time series has been identified as fat and magenta as cerebrospinal fluid. Data source is clinical study.
Injeq has patents issued and pending. The products have been used in two clinical studies and third study is currently in planning phase.Clinical Research
Clinical research has been on-going since 2014. A Study on spine structures and use of bio-impedance tissue sensing in adult population is currently ongoing. This investigation is performance study by nature and first results have already been published.
Following the research success in adult population a study about Injeq IQ-Needle use among pediatric patients prescribed for a diagnostic spinal fluid sample was started in August 2016.
A clinical study is about identification of liver tumors using bio-impedance core biopsy needle is another parallel research activity. The study was started in June 2016.
According to best practices of the industry also Injeq registers all studies in clinicaltrials.gov.
