Not every needle needs it. SonoCoat® earns its place where the procedure is ultrasound-guided and the needle is hard to see, which in practice means steep insertion angles, deep targets, or both. That covers oncology and diagnostic biopsy such as EUS-FNA and prostate, liver and breast procedures; vascular access for central venous catheters, PICC lines and arterial catheters; and regional anesthesia, where a nerve block depends on knowing exactly where the tip is. On a hypodermic needle used without imaging there is nothing for it to do. If your portfolio includes ultrasound-guided needles, that subset is where we would start.

Mechanically textured needles, whether laser-dimpled, etched or corner-cube patterned, are the established approach and they work. A structured surface scatters ultrasound back toward the probe instead of reflecting it away, and for many procedures that is enough. The trade-offs are geometric: the texture is cut into the needle wall, so it belongs to the needle it was designed into, and it changes the surface tissue moves against. SonoCoat® adds the acoustic function as a coating instead. Microspheres embedded in the layer scatter ultrasound in all directions rather than in the directions a pattern was cut for, which is what holds visibility at the steep angles where a smooth surface returns almost nothing to the probe.

That is what LipoCoat® is for on needles. Silicone oil gives a cannula its glide, and it is effective, inexpensive and thoroughly understood, which is why it has been the default for decades. It is also a mobile phase: some of it leaves the needle in use, it can interact with certain drug formulations, and silicone-free is appearing more often in tender specifications and in customer requirements. LipoCoat® is a bound bio-based layer rather than an applied oil, so it lubricates without anything that can migrate off the surface, and it reduces friction by up to 95 percent. It contains no silicone, no PTFE and no PFAS. Unlike SonoCoat®, this applies across the whole needle and cannula portfolio rather than to a subset.

They behave differently, so it is worth separating them. LipoCoat® is applied at 5 nanometers, far below the tolerance of any needle dimension, so outer diameter, wall thickness, bevel geometry and stiffness stay as you specified them. SonoCoat® is a functional layer of 35 to 90 micrometers, because acoustic scattering depends on the microspheres it carries and on the layer that holds them. Where a device sits in that range is set by the acoustic performance the application needs, and it is confirmed against your dimensional tolerances during the feasibility study rather than assumed. Insertion force moves the other way: the LipoCoat® top layer reduces friction by up to 95 percent, which means less tissue displacement on entry.

Yes, and on ultrasound-guided needles that combination is usually why the conversation starts. SonoCoat® goes on as the base layer and carries the acoustic function. LipoCoat® goes over it as a 5 nanometer top layer and carries the lubricity and anti-fouling function, in one development program under one quality system. LipoCoat® is a single-step dip coating at ambient temperature with no curing, no polymerization, no UV and no proprietary equipment, so it can run inside your own line. SonoCoat® carries microspheres and has its own process window, which the feasibility study establishes for your needle and your volumes. Three routes are open: we coat your components in our ISO 13485 facility, we transfer the process into your line, or we develop jointly through to the regulatory package.

LipoCoat® has passed the relevant ISO 10993 biocompatibility tests, covering cytotoxicity, sensitization, intracutaneous reactivity, acute and systemic toxicity, pyrogenicity and hemocompatibility, and the reports are available for your technical file. It is in a coated central venous catheter that received Taiwan FDA approval in May 2025. SonoCoat® is not yet on the market; its performance data is available on request. Both coatings enter your device as a component evaluated under your own conformity assessment, and because neither contains a medicinal or biocidal substance, neither moves your device into the ancillary substance route.
