“…In endovascular catheterisation procedures, friction against the luminal surface of a blood vessel along which the catheter passes is integral to the insertion, manipulation and removal of the catheter by the operator. A hydrophilic coating on the catheter can replace or supplement the lubricating action of the endothelial surface layer [6], facilitating catheterisation [7]. Existing hydrophilic coatings are formed by polymers with functional groups able to absorb water molecules, such as amino, hydroxyl or carboxyl groups.…”

The friction behaviour of new chitosan derivative coatings obtained by chemical modification of chitosan with fatty acids (linoleic and dilinoleic acid) has been investigated in order to explore their potential as endovascular catheter coatings and to benchmark them against commercially available coatings used in endovascular catheter applications. An in vitro tribological system was developed that was intended to represent to a limited extent the in vivo tribological conditions of a typical endovascular catheterization procedure. Continuous reciprocating sliding tests were carried out with uncoated and coated polymer specimens. The results showed that all of the coatings tested decreased the coefficient of friction compared to the uncoated polymer. Compared to a neat chitosan coating, the chitosan derivative coatings showed a clear reduction in the coefficient of friction to levels similar to those of the commercially-available coatings. A comparison between the friction results and contact angle measurements carried out on the coatings indicated that a range of contact angle values exists for which the friction coefficient is at a minimum. The reason for this is unclear and further studies are required in order to confirm and investigate the trend, especially within the context of hydrophilic lubricious coating development.

“…Polyamide 12 is currently one of the polymers most frequently employed to fabricate ABCs, but hydrophilic coatings need to be applied on its surface to enhance its biocompatibility and reduce the risk of complications during PTA. The use of coatings in medical devices has seen a massive evolution since the first described implementation in the late 1970s . At that time, polymeric coatings were essentially temporary, unbounded lubricants such as glycerin, silicone oil, and even olive oil with quick degradation through use and decrease of lubricity.…”

Polyamide 12 (PA12) is used in a variety of applications when low moisture absorption, good dimensional stability, and toughness are required. Polyamide 12 is one of the polymers most frequently employed to fabricate angioplasty balloon catheters; however, its high hydrophobicity and chemical inertness require the application of coatings to make its surface more hydrophilic and biocompatible. In this work, an alternative method, based on the photochemical reaction of PA12 with a hydrophilic aromatic azide, was developed. Static and dynamic contact angle measurements evidenced that the surface modification process was able to improve PA12 wettability and that the effects were retained even after 12 months from surface treatment. Polyamide 12 modification resulted in an increase of its surface free energy, as evaluated by the van Oss, Good, and Chaudhury method. X‐ray photoelectron spectroscopy confirmed the presence of the aromatic azide on PA12 surface. Finally, compliance tests showed that the modification process did not reduce the mechanical performance of balloons.

“…Damage to the extracellular matrix (ECM) will require a wound healing response and if it goes wrong this can lead to fibrosis [6]. Thus manoeuvrability represents a critical design feature for these catheters [7]. This feature is highly dependent on minimising the coefficient of friction between the catheter and the blood vessels.…”
