Designing new infusion catheters is a complex process…

Designs must be made around strength as an underlying quality, consistency of production and quality. Bonded junctions must meet pull-test strength requirements; formed tips must be smooth and flash-free; tubing must be flexible yet rigid enough to avoid kinking; and flow rates through the lumen must meet exacting requirements. catheters incorporate a coiled wire that forms the lumen and guarantees these qualities.

Hole position, size and quality are critical aspects to the form and function of the catheter design…

Evidence shows that the proximal holes in a catheter are the primary sites of blockage and unlike blockages at distal holes, occlusion of proximal holes results in complete catheter failure. Our catheters with varying hole diameters, spread in a helix along the catheter’s fenestrated segment allow fluid to enter the catheter more uniformly along its length, thereby reducing the probability of it becoming blocked.  Even flow means better pain management. catheters are precision drilled by laser beam to guarantee these qualities.
