Development of an electrolytically-detachable microcoil for intracranial aneurysms / 中国医疗器械杂志

An electrolytically-detachable microcoil is introduced here in the paper. The testing results indicate that, the microcoils have stable mechanical properties, clear radiographic images and fine insulation performance. Their detaching time varies from 30s to 200s when voltage changes from 2V to 5V.

Factors influencing the temperature-sensing accuracy of ablation catheters / 中国医疗器械杂志

Factors influencing the temperature-sensing accuracy of an ablation catheter are analyzed, in this paper, from the two aspects of the thermocouple temperature sensor, which are the TC length and the TC hole's diameter of the ablation electrode. Meanwhile, differences between products from different companies are given too.
