Implantable Laser Cut and
Laser Welded Components

Seisa offers laser cutting for implantable medical device components and laser welded metals to meet your needs. For example, we offer laser cutting for neurovascular and coronary devices and large aortic stent grafts and valve components. We also provide laser cutting of nitinol, cobalt-chromium, stainless steel and other biocompatible metals.

Our state-of-the-art laser machining and world class finishing processes rival any in the industry.

Seisa provides a wide range of metal cutting capabilities and specialties in nitinol and novel alloys. We also have advanced art tube cutting precision equipment and decades of laser cutting and welding expertise. Seisa offers implantable devices like forming, shape setting, surface finishing and additional nitinol processing capabilities.

Our nitinol shape setting processing capability includes a wide range of laser-cut and wire-formed devices. We use innovative tooling with unique configurations and a process optimized for mechanical and thermomechanical behavior, rapid heating/cooling cycles and precision temperature control. In addition, our in-house tooling capabilities enable rapid prototyping iteration and development.

Seisa’s world-class surface finishing includes different process capabilities. Some of those include precision deburring, polishing and chemical etching operations, dry and wet honing, tumbling, mechanical surface finishing /micro blasting, electropolishing and chemical processing. We also offer complete removal of HAZ, corrosion and fatigue resistance and biocompatibility tests for medical devices.

medical device manufacturing class 2 and class 3 expertise

We offer nitinol wire-formed devices and specialize in forming and finishing for AAA / TAA stent-grafts and components. With semi-automated forming processes, we obtain tight tension control and consistent part shape and performance for our customers. Seisa offers in-house tooling design and manufacturing. We can make additional tooling sizes for any wire-formed Z stents.
