Heat Shrinkable Tubing
Manufactured from a variety of polymers, heat shrink tubings are used for product and manufacturing applications including electrical insulation, mechanical reinforcement, encapsulation, marking and identification. They are available in standard or long continuous lengths and in precision cut pieces.

Needles, Instruments & Hypo-tubing
DSA focuses on OEM surgical entry devices, sampling needles and probes for medical devices and analytical chemistry. These capabilities have also found wide industrial use for fluid transfer and filling. We specialize in the FDA registered contract manufacture and assembly of laparoscopic instruments and sub-assemblies.

Tubing, Needles and Cannulae
DSA's principals fabricate many types of needles and instruments from stainless steels, exotic metals and plastics. We carry a large inventory of hypodermic tubing, hubs, fittings, wire and other components to assure rapid turnaround on your requirements. Close tolerance run-out, dimensional and surface finish specifications are welcomed.

A wide variety of technologies are available in-house, including:

  • CNC turning and milling
  • CNC EDM and precision mechanical drilling
  • CNC Laser welding and plasma arc welding
  • CNC Grinding (surface and centerless)
  • Swaging, honing and tumbling
  • Brazing and soldering
  • Chemical and Laser Marking
  • Ultrasonic cleaning and passivation
  • Precision bead / abrasive blasting
  • Proprietary finishing and polishing processes
  • Thermal induction for plastic-to metal bonding

Design assistance from experienced biomedical and manufacturing engineers is available.

Here are some standard sizes of tubing available for Immediate Shipment and an overview of some standard point styles for needles and cannula.

Trocars, Pins & Coils

Trocars, Tunnelers and Pins
These solid instruments are made from stainless steels, aluminum and nitinol wire or bar, and range in size from 0.008" (200 microns) to over 0.500" (12.7 mm) in diameter. They often feature a cutting point or blade on the distal end of many configurations, and a variety of designs such as a handle, finger button, barb, or threaded fitting on the back or proximal end. DSA's principals achieve the sharpest cutting edges and points on these devices with a tight focus on the surface finish of the body.

Springs and Coils
Capabilities include high volume and R&D production of the following:

  • Consistent OD Coils +/- 0.0002"
  • Coil ODs from 0....
