Stents
What is a stent?
It is a nickel-titanium metal component implanted in tubular areas of the body, such as blood vessels and the colon. The stent is used to physically widen passages and address constrictions or blockages.
Braiding Wires, Cutting Laser Tubings
Domestic stents (manufactured in-house) are also supplied on a made-to-order basis. Please contact us for materials other than nickel-titanium.
Braided Stents
Nickel-titanium wires are braided in-house to your specified size and design requirements.
X-Ray Opaque Marker Coils
We can also manufacture and assemble X-ray opaque marker coils using our spring processing technology.
Laser Cut Stents
Nickel-titanium tubing is laser cut and expanded to your specifications. Through our overseas subsidiaries, we can also procure specialty alloy tubing which can be difficult to obtain locally.
Finish process (Electro Polishing)
What is Electropolishing?
Electropolishing smooths metal surfaces and edges by electrolysis. This results in the reduction of surface irregularities.
Before Electropolishing
After Electropolishing
Effects of Electropolishing
The beneficial effects of electropolishing for medical devices include:
- Removal of small burrs
Makes micron-level deburring possible. - Formation of passive film
Improves corrosion resistance. - Removal of oxidized film
Contributes to electrical conductivity - Prevention of metal fatigue
Improves durability.
Electro Polishing Applicable Metals
- Nitinol example : Laser Cut Stents
- Stainless Steel
- CoCr
- Titanium
Laser Processing
What is laser Processing?
Laser processing uses laser energy for precision cutting, welding, marking, and many other manufacturing-related process.
Laser Processing Examples
Laser Cutting; Thin Sheet, Tubing
Fine cuts in straight tubing introduces flexibility.
Laser Welding, Spherical Surface Process
Laser Welding
Spherical Surface Process
Marking
Advantages of Laser Process
- Thin sheet metal processing is possible.
- Beautiful cut cross-sections
- Fine machining is possible.
- Not dependent on the hardness of the metal
