Micro Coils & Fine Wires
One of the major challenges facing the designer of invasive medical devices is to fit the physical size of the device within the constraints imposed by the body region for which it is intended. Invasive devices inserted into the body – via catheters, minimally invasive procedures, and permanent or temporary implants – are undergoing a continuous process of miniaturization, with the purpose of reaching otherwise inaccessible regions in the body, minimizing disruption of regular body functioning, minimizing energy consumption, and increasing the lifetime of implanted components.
In response to this challenge, Benatav employs design and production technologies that use ultra-fine insulated wires to manufacture micro coils. These technologies are based on the in-house development of an array of techniques for handling insulated copper wire at any diameter, down to the finest serially manufactured size of 59 AWG (9 microns). Thus for example, by employing dedicated micro machining technologies, the company serially manufactures coils having over 1000 windings, smaller than the head of a pin!
Benatav's long-standing experience in developing and implementing these technologies enables mass serial production while meeting the standards required by medical applications, both of disposable products (such as catheters) and of long term products (such as implants, pacemakers, etc.). Prior to mass production, each component undergoes a careful design process. The chief challenges of this process include meticulously creating design specs based on the component’s technical requirements, and then designing and creating tooling and manufacturing machines accordingly, while meeting stringent standards of quality and reliability.
Benatav's micro coils offer designers of medical devices a vast array of capabilities, and open the door for endless miniaturization applications. These capabilities include:
§ Transferring control, monitoring, and logging data to/from miniature implants
§ Transferring energy to implants requiring battery charging or electrical charge input for activating and operating their systems
§ Radiating energy for RF treatments, heat treatments, or electromagnetic radiation-based treatments
§ In-vivo magnetic navigation, employing a local or external magnetic field
Some of the applications that can use Benatav's micro coils include:
§ Diagnostics: wireless communications with miniature implants serving as sensors, whether physiological (blood pressure, heartbeat), glycemic, or flow (blood, respiratory)
§ Active implants: monitoring/controlling miniature implanted pace-makers, or as deep brain stimulation components in pain management implanted devices
§ Therapeutic applications: as end devices in electrophysiological treatments (cardiac, neural, brain), or in electricity-based ablations (microwave and RF)
§ Navigation and orientation: for accurate navigation of targeted drug delivery, for targeted radiation catheters, for stents positioning, for highly-accurate ablations, for implanted markers, for inter-body tagging, and for endoscopic, gastroscopic, colonoscopic, laproscopic, and other similar procedures
