Custom made sewing/suturing machines!
for class 3
medical devices:
Sew Fine is a
company specializing in hand crafted sewing equipment for unique applications.
Many products
are designed and prototyped by hand stitching. When the product goes into
production often there is no sewing technology capable of producing the
correct stitch in the required location. We develop sewing equipment for the
products that can not be sewn by conventional technology's. Our experience
started with designing sewing factories and the related specialty equipment (trade
secrets) in industries ranging from
Haute
couture,
furniture, golf bags, cold air inflatable, class 1 medical and class 3 medical
devices. Our primary focus in in the medical industries but we are open to
working with other custom sewing projects.
For many
years class 3 medical device manufacturing has been a combination of new
technologies and highly skilled hand sewing operations. This combination of
talent and technology is used to produce finished implantable devices. Many
medical devices manufacturers have replaced much of the hand sewing with
automated sewing equipment (vision guided robotics). This offers a large
reduction in manufacturing time, reduced labor related injuries, and a more
precise sewn product. Numerous types of class 3 medical devices have been
approved by the FDA using Sew Fine's sewing technologies.
We have
developed several clean room sewing/ suturing workstations used in the
production of coronary care devices. Our expertise range from biological
prosthetic to angioplasty products . We work directly with our customers to
develop custom made sewing equipment to replace many hand sewing presses, one
seam line at a time. We offer medical device consulting for sewing/ suturing,
design and modeling, prototyping and production sewing/ suturing equipment. We
have a complete machine shop including 4 axes CNC machine center.
Sew Fine
specializes in sewing small and very small tubular medical device. We are
interested in working on extremely challenging sewing applications. If you
have a sewing project that can not be sewn with conventional sewing technology
we would be happy to work with your team to develop a automated solution to
your sewing challenges.

devices, and biological sewing.
The
contact components of the sewing device can be cleaned or replaced between
lots to prevent cross-contamination. Reusable parts can be autoclaved.
Disposable parts can be sterilized.
