Development of an implantable carotid artery training occluder / 实用口腔医学杂志

ABSTRACT

objective: To develop an accurate, reliable and efficient carotid artery compression training device .Methods:Adopting present technology for production of skin dilators in combination with anatomical characters of human carotid artery, an implantable carotid artery training occluder (ICATO) was designed and manufactured. The mechanical properties were tested and the carotid artery occlude effect was investigated in 12 dogs. Results: The expansion stress of the water cyst and duct of the occluder was 40 kPa, that of the water imput valve 30 kPa,tear stress of the nylon cloth was 5 kg. The carotid artery could be completely blocked at the pressure of 19 kPa produced by the occluder. Conclusion: ICATO can obstruct carotid artery for the purpose of compression training of carotid artery.
