Custom micro coil magnetic core inductor coil for medical application

Feature

Micro coils are essential components of medical devices. One of the major challenges faced by designers of invasive medical devices is to accommodate the physical size of the device within the constraints imposed by the target body region. Invasive devices, whether inserted into the body via catheters, minimally invasive procedures, or through permanent or temporary implants, are continuously being miniaturized. This progress aims to reach otherwise inaccessible regions within the body, minimize disruption of regular body functions, reduce energy consumption, and increase the lifespan of implanted components.

Recognizing the engineering challenges posed by medical device miniaturization, Golden Eagle has developed a unique array of capabilities, both in designing and producing miniature coils, mini coils, and micro/mini sensors, based on ultra-fine wires, and in connecting the wires to adjacent miniature components.

Golden Eagle is specialized in providing custom micro-coils for a variety of applications. We have specialized equipment capable of winding ultra-fine wire as thin as 10 micron and producing coils as small as 0.3mm . Coils can be designed with or without cores in a variety materials including mu-metal, ferrites, plastic and polyimide. Custom micro coils can be developed with lead configurations for manual assembly . Our micro-coils can be wound using copper or other special alloy wires. Multiple coating, over-molding, packaging and testing options are possible.

Leveraging on our custom equipment/automation capabilities, we can develop custom equipment and tooling to integrate winding, assembly and test (electrical and optical measurement) in fully automated and semi-automated processes to produce:

• Micro antenna coils
• Micro air coils
• Micro voice coils
• Micro inductor coils

Application

• Diagnostics: wireless communications with miniature implants serving physiological, glycemic, and flow sensors
• Active implants: monitoring/controlling miniature implanted pace-makers, deep brain stimulation components, etc.
• Therapeutic applications: as end devices in electrophysiological treatments and in electricity-based ablations
• Navigation and orientation: targeted drug delivery, targeted radiation catheters, stents positioning, highly-accurate ablations, implanted markers, inter-body tagging, and endoscopic, gastroscopic, colonoscopic, laproscopic, and other similar procedures
