At Demax we continually refine the science of intervention. Our latest advancement, the Coil Reinforced Catheter, combines the tensile strength of precision-braided alloys with the gentle touch of next-generation polymers. In this article we share the engineering logic, the clinical impact, and the partnership opportunities that help physicians deliver safer, faster, and more predictable care.
Engineering Strength with Surgical Sensitivity
A catheter must steer through tortuous anatomy, withstand repeated torque, and still protect delicate tissue. The Coil Reinforced Catheter solves this challenge by marrying a three-layer design with micro-engineered reinforcement.
1) Tri-Layer Construction
•Outer Layer – TPU, Pebax, or PA provides a low-friction, kink-resistant skin that slides smoothly through introducers and valves.
•Middle Layer – SUS304 stainless steel, nickel-titanium, or flat-wire braid delivers radial strength while a helical spring core absorbs sudden bends.
•Inner Layer – PTFE or Pebax ensures a glassy lumen for seamless fluid flow and device delivery.
2) Key Performance Benefits
✅High torque transmission for precise tip placement
✅Consistent pushability that resists buckling in long lesions
✅Proven anti-explosion rating for sudden pressure spikes
✅>30 % reduction in bending fatigue versus non-reinforced tubes
Because every procedure is different, Demax offers custom weaving densities (8 – 72 spindles) and patterns (1 x 1, 1 x 2, 2 x 2). Inner diameters range from 0.5 mm to 15 mm with tolerances as tight as ±0.0125 mm, while wall thickness can be tuned from 0.07 mm for neuro work to 3 mm for large-bore access.
3) Why Materials Matter
Nickel-titanium memory wire adds gentle elasticity. Flat stainless wire maintains a low profile without sacrificing hoop strength. By combining these alloys inside a Pebax jacket we create a catheter that flexes where you need it to – and nowhere else. Clinicians feel less “whip,” gain accurate haptic feedback, and navigate complex vessels in fewer fluoroscopy shots. That translates into shorter procedure times and reduced radiation for everyone in the room.
Real-World Clinical Benefits Across Specialties
Strong engineering means little without tangible outcomes. Since its launch, the Coil Reinforced Catheter has shown measurable gains in angiography, neuro-intervention, and minimally invasive surgery.
• Vascular Interventions
Interventional cardiologists demand fast contrast injection, tight curve control, and zero compromise during stent delivery. The catheter’s high burst resistance allows full 8 bar injections without ballooning, while its smooth PTFE lumen keeps pressure gradients low. Operators report a clearer angiographic roadmap and sharper device response during balloon inflation.
• Neurovascular Access
Navigating cranial vessels tests every millimeter of a catheter. Our braid-spring hybrid maintains column strength through the carotid siphon and seats microcatheters with confidence. Fewer exchanges mean lower embolic risk, and the lubricious inner wall preserves coating integrity on fragile neuro coils.
• Endoscopy and Urology
✅Stable suction during gastroscopy even when sharply flexed
✅Reliable irrigation in ureteroscopy without lumen collapse
✅Smooth passage through tight scopes thanks to thin-wall Pebax
In a multicenter study, clinicians recorded a decline in overall procedure time and a drop in accessory exchanges when switching from a standard polymer catheter to the Demax Coil Reinforced Catheter.
• Wider Applications at a Glance
- Angiography Catheter – rapid, high-volume infusion
- Guiding Catheter – robust backup support for device delivery
- Microcatheter – neuro and peripheral embolization
- Distal Access Sheath – deep vessel navigation with stable tip control
- Diagnostic Imaging – consistent contrast bolus in CT, MRI, and ultrasound
Every gain – whether shorter fluoroscopy time, fewer passes, or lower contrast dose – adds up to better patient outcomes and leaner hospital workflows. That is why procurement managers see the catheter not as a cost but as a strategic asset that unlocks efficiency across service lines.
Partnering with Demax for the Next Leap Forward
Innovation thrives when engineers and clinicians share real-world feedback. Demax welcomes joint development, private-label production, and rapid prototyping partnerships.
●Select lumen size, wall thickness, and working length
●Choose braid density, wire profile, and alloy mix
●Tailor tip softness, radiopaque markers, and hub design
We analyze field data, bench top studies, and voice-of-customer interviews. Iterative updates – such as enhanced flat-wire geometry for even higher kink resistance – arrive in regular product refreshes without disrupting supply. This agile cycle keeps clinicians at the forefront of care and safeguards long-term purchasing value for distributors.
Looking Ahead
By 2027, analysts predict a double-digit CAGR for coil-reinforced devices in minimally invasive therapy. Demax intends to lead that wave with solutions that balance power and finesse. When physicians grip a Demax Coil Reinforced Catheter, they feel a tool engineered for today’s complex anatomy – and tomorrow’s.
