One of the significant challenges facing designers of invasive medical devices is accommodating the physical size of the device within the constraints imposed by the target body region. Devices inserted into the body – via catheters, minimally invasive procedures, or permanent/temporary implants – are continuously being miniaturized. This process aims to reach otherwise inaccessible areas in the body, minimize disruption to regular bodily functions, reduce energy consumption, and extend the lifetime of implanted components.
In response to this challenge, Benatav employs design and production technologies that utilize ultra-fine insulated wires to manufacture micro coils. These technologies are based on in-house developed techniques for handling insulated copper wire of any diameter, down to the finest serially manufactured size of 59 AWG (9 microns). For instance, the company employs dedicated micro-machining technologies to serially manufacture coils with over 1000 windings, which are smaller than the head of a pin!
Benatav’s extensive experience in developing and implementing these technologies enables mass serial production that meets the standards required by medical applications. These applications range from disposable products such as catheters to long-term products like implants and pacemakers.
Prior to mass production, each component undergoes a thorough design process. The chief challenges of this process include meticulously crafting design specifications based on the component’s technical requirements. Subsequently, tooling and manufacturing machines are designed and created accordingly, all while meeting stringent standards of quality and reliability
