Advanced neuroendoscopy with ultrasonic aspiration

When removing intra- and paraventricular lesions, it may be preferable to use a minimally invasive approach. In contrast to open surgical procedures, minimally invasive procedures allow tumors to be resected through a narrow access path. Söring supports this surgical technique by providing the endoscopic Micro instrument ENP, the world‘s only endoscopic ultrasonic aspirator. The exceptionally long sonotrode is guided through the working channel of an endoscope. This enables the simultaneous fragmentation and aspiration of deep-seated tumors of different consistencies, thus opening up new possibilities for minimally invasive surgery 3.

The ENP ultrasonic aspirator can be used with the neuroendoscopic system AESCULAP® MINOP® InVent from BBraun or GAAB from KARL STORZ.

“The endoscopic ultrasonic aspiration with the Micro instrument ENP is a safe and reliable technique for extensive decompression or complete removal of intra- and paraventricular lesions.”

"The ultrasonic aspirator allows a minimally invasive surgical resection of intra-/ paraventricular tumors. Especially in case of limited vascularized tumors, we are able to reduce the operation and anaesthesia time.”

Prof. Dr. med. Ulrich W. Thomale, Head of Pediatric Neurosurgery, Charité Universitaetsmedizin Berlin, Germany


  • resection simply via a neuroendoscopic approach
  • fast resection1 by simultaneous fragmentation and aspiration of tissue
  • clear visibility due to continuous irrigation flow 2
  • also efficient for firmer tumor tissue 3,4
