Cautery Tips

PTFE Coatings That Reduce Tissue Buildup and Surgical time

Our medical coating systems are infused and fortified with PTFE to greatly reduce tissue sticking or buildup on cautery tips known as “eschar”. Eschar buildup is the most common issue associated with the intraoperative use of electrocautery and can be problematic for the end user. This buildup will also directly affect the dispersion of electrical energy and prevent proper sealing of small and large vessels and also promotes longer surgical time. This is where utilizing our 850g-1040 coating can greatly reduce the coefficeint of friction and assist with easy clean ability, minimizing any sticking or charring on the electrode.

Coating Application & Recommendations

All Miller-Stephenson’s Fluoropolymer coatings can be applied via spray, dip or spool-to-spool methods. Proper post-application curing equipment is critical to guarantee performance and durability. Acceptable curing equipment includes high-temperature ovens which can safely maintain temperatures of 246 °C  (475 °F) or utilize IR ovens. This is to ensure proper sintering of the coatings onto the wire and promote the best surface characteristics that can be achieved.
