Fusion Design engineers have a long-track record of developing innovative solutions to mechanical challenges. Past projects include minimally invasive devices, patient monitoring, surgical tools, orthopedic implants, laboratory analysis, diagnostic equipment, laser eye surgery and wearable devices.
Many of the products we develop have precision mechanical components like optics, lighting, micro-mechanisms, fluid valves, precision motion control, custom UI, shielding, UV sterilizers, thermal forming and custom manufacturing equipment for medical devices. Here are a few examples:
Fiber Optic Camera System and Blade Assembly for Out-patient Treatment for Carpal Tunnel

One of the biggest problems with all endoscopes is getting light where you need it inside the body. We have experience developing camera-based systems and providing light sources while managing the thermal issues of the light source.
Precise Motion Control for Optics
Optics require very precise motion control and stability. Our engineers use minimal part count design and material selection to meet the tightest tolerances found in today’s optical systems. In addition, our designs are reliably manufactured in volume

Fluid Transfer for Bio and Med Tech
Fluid transfer is all about viscosity, pressure, flow rates, temperatures, volumetrics and controlling flow channel sizing. Even in the smallest wearable, getting fluid exactly where you need it can be challenging. Our engineers have developed fluid control systems from small wearable patches to large gluing systems and many devices in between.

Custom Manufacturing Equipment for Medical Devices
We are experienced in designing custom machines that combine multiple functions, such as precision heating, shrinking, cutting, bonding and inspection. This custom machine does precision heating, shrinking, cutting, and bonding to make precision catheters. Precision heating may use methods such as infrared heating, laser heating, or induction heating to achieve precise temperature control for specific materials. Necker machines heat shrinkable materials such as plastics or rubber to a precise temperature which applies radial pressure to create a tight, secure seal. These often use integrated adhesives for bonding materials together.
Joysticks
Joysticks are a great solution when you need precise user control. This eye surgery machine is a good example of both optical design and joysticks. For eye surgery equipment, the doctor needs exact control over the position of the laser target. In this case, the system has X, Y & Z alignment control of laser targeting by moving the patient via a joystick.
