Controlled study of inline radiofrequency coagulation-assisted partial nephrectomy in sheep

Background. Primary or secondary tumors of kidney often are managed by partial nephrectomy. Intraoperative blood loss can be significant. Laparoscopic partial nephrectomy may be even more challenging. We developed the Inline radiofrequency coagulation (ILRFA) probe for liver surgery. It uses radiofrequency energy to make a linear coagulative plane and considerably reduces bleeding during parenchymal transection. In this study we tested the efficiency of ILRFA in ovine kidney

Controlled study of inline radiofrequency ablation (ILRFA) assisted transection of ovine liver

Background. Liver resection is now a standard treatment for primary and secondary hepatic tumors around the world. Intra-operative blood loss during liver resection is a major factor associated with morbidity and mortality. We have developed a new instrument using radiofrequency energy (ILRFA), which is intended to achieve coagulative ablation in a plane. This plane can then be cut through with a scalpel, ultrasonic dissector, or diathermy with minimal blood loss
