The medical device industry is seeing all kinds of innovations, but people often overlook the myriad medtech outsourcer technologies making innovation possible.

From tiny sensors, magnets and cameras to materials and adhesives that get the job done, contract manufacturers and other suppliers are supporting the medical device industry in myriad ways. They’re enabling everything from connected medical devices going into homes to improved implantable devices — and so much more.

Many medtech outsourcer innovations were on display this month at MD&M West in Anaheim, Calif.; it’s one of the largest medical device manufacturing events in the world. Read on to discover some technologies that especially got our attention.


TE Connectivity - Ultrasonic air-in-liquid detectors

TE Connectivity’s AD-101 is an ultrasonic sensor that can detect bubbles 4 µl and larger in IV lines.

The sensor can be used in infusion pumps, dialysis machines, apheresis, auto-transfusion and 3D printing applications. It features bubble detection from a 1 mm tube, integral electronics, occlusion option, fluid differentiation and 3.3 and 5 V input options.

When an air bubble passes through the sensor, the housing lights up to alert the user.

TT Electronics - Electromagnetics

TT Electronics makes magnetic devices for medical applications. The devices are used for a number of things including, programming implantable devices, wireless charging of implants, surgical navigation and more.

The company’s electromagnetic coils give high reliability for power and communications in implantable and external medical devices. Devices include external defibrillators, implantable defibrillators, kidney dialysis equipment, ablation therapy systems, sleep apnea equipment, RF programming devices, hearing aids and a number of other diagnostic and testing equipment.

TT Electronics’s ultra-fine wire winding can be as small as 58 gauge using gold, silver and platinum and copper wire and its telemetry coils are used as customizable components in pacemakers, defibrillators, neurological implants and cochlear implants to communication with external programming devices.

Other electromagnetic coils include inductive charging coils, which are used in pacemakers, defibrillators, neurological implants and cochlear implants to charge the batteries in the device. Field generation coils are used in surgical navigation, internal diagnostic positioning and transcranial magnetic stimulation systems in bone healing, migraine treatment and drug addiction therapy.

OmniVision - OVM6946 camera module

OmniVision’s OVM6946 CameraCubeChip is a wafer-level camera module that is used in single-use medical devices like endoscopes.

The camera module is built on the company’s OmniBSI+ pixel architecture and has 400 x 400 resolution at 30 fps and a 120º diagonal field of view. It also has a focusing range from 3mm to infinity.

OmniVision’s OVM6946 is 1.05-by-1.05-by-2.27 mm in size and have been used in a number of medical devices that require small cameras. It has lower power consumption with a single 3.3V power supply.

Eastman - Medical polymers

Eastman has a number of medical-grade polymers that are currently being used to make devices and packaging that meet or exceed stringent compliance and market demands.

The polymers are bisphenol A free, halogen-free, not manufactured with ortho-phthalates, easily recyclable in the medical waste stream and have improved durability for harsh environments.

Eastman’s Tritan copolyester is compatible with aggressive cleaners and disinfectants and don’t break down after multiple cleanings. It is able to withstand a chemical attack from Virex Tb, which is a common disinfectant in hospitals and clinics. Typically, the more a plastic is cleaned with a harsh disinfectant, its chances of forming cracks increases.

The company’s polymers have been used in Mindray’s patient monitors. Since the monitors move with the patient throughout their entire stay at a hospital, the system comes into contact with various hospital-acquired infections and needs to be cleaned continuously without breaking down the housing.
