Nitinol Wire Specifications

Wire Rope / Stranded Wire

Wire Rope / Stranded Wire is a type of wire that is composed of multiple thin wires, twisted together to form a strong and flexible structure. Wire Rope / Stranded Wire is commonly used for orthopedics, endoscopic, where flexibility and strength are critical requirements.

Torque Rope

Torque Rope is made by twisting multiple strands of wire together. Unlike other wires, torque rope allows for the transmission of rotational force with minimal loss. Torque Rope is commonly used for Endoscopic devices and catheter devices. Imagine a miniature driveshaft – you twist one end, and the other end rotates in the same direction. This precise control is crucial for certain endoscopic instruments.

Micro Catheter

Micro catheters are commonly used in procedures such as angiography, endovascular therapy, embolisation, where precision and control are critical requirements. They are inserted into the body through a small incision or puncture and guided to the target site using fluoroscopy or other imaging techniques. We are able to offer state-of-art precision micro catheters.

Torque Coil

Torque coils are made by coiling several strands as thin as a hair and layering them in 2, 3, 6, 8 or 12 layers. Torque coil provides rotational stability and control. Torque coil is a specially designed that is added to the distal end of the device, which allows the device to rotate and maintain its position during procedures. After 8 years of development, our Japanese manufacturer became capable to offer state-of-art precision Torque coils.

Hypotube (Hypodermic tube) with welded wire

Hypotube or Hypodermic tube is a small, thin-walled metal tube used in various medical applications, particularly in Low-Invasive Surgery which requires shape retention and rotational transmission to keep compact and flexible and fit inside a human blood vessel. Hypotubes are commonly made from stainless steel or other materials with some coatings inde such as copper with specific properties suitable for individual medical purposes.

Accuracy of cut (no burr, easy to sterilize) is critical for the hypotube to operate properly during surgery. To satisfy both the material and processing (cutting, coating etc) at the high level of accuracy is very demanding, so that the number of companies that can deliver Hypotubes in the world is limited.

Enserve arranges a combination of high-quality materials and processes from Japan. Enserve is able to offer not only Hypotube itself, but also the whole “Assy (Hypotube + Wire + Welding)”.

Medical Instruments

Enserve also offers medical instruments with distinct advantages.

Japanese Craftmanship

We respect the craftmanship of every single process of manufacturing for our medical instruments. Because medical instruments are mainly hand made, the attention to the details are essential and manufacturing know-how and tips of craft men must be highly appreciated to achieve end users comfort of critical applications.

The end users (doctors) in Japan severely evaluate the usability of medical materials. For our manufacturing, Japanese craftmanship is essential for these end users’ sensitive and demanding requirements.

Suitable for Small Hands

Medical Instruments are often used for more than 2 hours for surgeries. If doctors continue using the wrong size medical instruments, they get more tired and loose concentration during a surgery. Japanese male hand length is 20mm shorter than Caucasian male hand length. Our instruments fit with Non-Caucasian males to use comfortably for long hours. Generally, the average height correlates the average hand size. This reference provides average height data by countries. We are confident that smaller handed doctors feel comfortable and less fatigue with our instruments.

Available Instruments

We mainly introduce forceps and shears for medical use. Besides that, we can also produce stethoscopes, Nasal Speculas, Ear Speculas, Koos Knives, etc. There are many more kinds of products available. We have both multiple use and single use (disposable) products (details about single use instruments). Please feel free to contact us.


Our Medical Instruments are typically used for medical, beauty, veterinary, and dental applications. We are open for other applications such as hobby applications (fish hook removal, plastic modeling).

We can help you with the specifications and types products that are suitable for your use case. 
Please feel free to contact Enserve if you have any issues about QCDs of steel instruments or medical wires.
