The 3M universal electrosurgical pad 9100 Series with proprietary safety ring is a breakthrough in electrosurgical pad technology. This pad is smaller in size - a mere 15 sq.in. so it's very easy to place, while maintaining the safety of traditional pads up to 33% larger in conductive surface area. The universal pad demonstrates a maximum temperature rise similar to traditional pads up to 33% larger and meets the performance criteria set forth by the Association for the Advancement of Medical Instrumentation (AAMI) for maximum safe temperature rise (AAMI Standard HF-18, 2001 Revision, Section 4.2.3.1).
