Special Issue Information

Dear Colleagues,

Medical Catheters are well established and ubiquitous in modern clinical practice. Optical Fibre Sensor (OFS) technology for medical sensors is a rapidly-growing field of research, which lends itself well for use within catheters for making a wide range of medical and/or biomedical pressure. OFS have many attractive features which allow them to be effectively deployed as sensors within existing and purpose designed novel medical catheters. These include miniaturization, immunity to external electromagnetic radiation, e.g., in the case of Magnetic Resonance Imaging and other imaging/scanning systems, their ability to be functionalised, and specific performance advantages such as capability for rapid response, high sensitivity coupled with specificity, especially as chemical and/or physical sensors in biological sensing.

The concept of the ‘Smart Catheter’ approach is designed to transform conventional catheters and optical fibre sensors into a robust technology which is ideally suited for undertaking a wide range of in vivo real time medical measurements. The Optical Fibre Sensing approach means that the light signal interaction with its environment can take place at the tip of the fibre or along an extended surface in the sensor location e.g. by evanescent wave interaction. The broad approach to sensing means that several different parameters can be measured covering a wide range of clinical applications.

Specifically, Smart Catheter technology platforms can be subdivided in three main classes:

– Single point sensor within catheter;

– Quasi-Distributed or multi-point sensor within a catheter;

– Modified catheter coupled with the sensor. In this case, the catheter itself has been modified or designed from scratch to play an important role in coupling the measurand signal to the sensor.

This Special Issue is proposed to collect invited manuscripts written by the leading authorities in the field. Specifically, with special focus on chemical and biological sensing applications, this Issue will include both research and review papers dealing with:

- successful development and/or demonstration of novel Smart Catheter based sensing systems;

- integration of Smart Catheter with existing medical systems;

- Advancements in materials for use in Smart Catheters e.g. coatings for improved performance;

- emerging methodologies for fabrication methods feature placement on Smart Catheters, e.g., using femto-second laser based systems.

Double Assurance of Epidural Space Detection Using Fiberoptics-Based Needle Design and Autofluorescence Technologies for Epidural Blockade in Painless Labor

Purpose: Technology of reflectance spectroscopy incorporated with auto-fluorescence spectroscopy were employed to increase the safety of epidural placement in regional anesthesia which is generally used for surgery, epidural anesthesia, post-operative pain control and painless childbirth. Method: Ex vivo study of auto-fluorescence spectroscopy was performed for the para-vertebral tissues contained fat, interspinous ligament, supraspinous ligament and ligamentumflavum by multimode microplate reader at wavelength 405 nm for the purpose of tissue differentiation. A specially designed optic-fiber-embedded needle was employed to incorporate with both reflectance and autofluorescence spectroscopies in order to probe the epidural space as double assurance demands. In vivo study was carried out in a Chinese native swine weighted about 30 kg under intubated general anesthesia with ventilation support. The reflective (405 nm) and autofluorescence signals (λ and λ*) were recorded at 5 different sites by an oscilloscope during the needle puncture procedure from skin to epidural space in the back of the swine. Results: Study of either autofluorescence spectroscopy for tissue samples or ex vivo needle puncture in porcine trunk tissues indicates that ligmentumflavum has at least 10-fold higher fluorescence intensity than the other tissues. In the in vivo study, ligamentumflavum shows a double-peak character for both reflectance and autofluorescence signals. The epidural space is located right after the drop from the double-peak. Both peaks of reflectance and fluorescence are coincident which ensures that the epidural space is correctly detected. Conclusions: The fiber-optical technologies of double-assurance demands for tissue discrimination during epidural needle puncture can not only provide an objective visual information in a real-time fashion but also it can help the operator to achieve much higher success rate in this anesthesia procedure.

Placing the needle inside the epidural space for locoregional anesthesia is a challenging procedure, which even today is left to the expertise of the operator. Recently, we have demonstrated that the use of optically sensorized needles significantly improves the effectiveness of this procedure. Here, we propose an optimized configuration, where the optical fiber strain sensor is directly integrated inside the epidural catheter. The new design allows the solving of the biocompatibility issues and increases the versatility of the former configuration. Through an in vivo study carried out on a porcine model, we confirm the reliability of our approach, which also opens the way to catheter monitoring during insertion inside biological spaces.
