Doppler System for Neurosurgery The essential and cost effective intraoperative microvascular instrument that provides you with the sound information you need The VTI 20 MHz Microvascular Doppler System is ideal for intraoperative use in neurosurgical procedures. Combining a miniature probe tip with a high operating frequency, the system emits a tightly focused signal with a shallow depth of signal penetration, imparting a level of precision essential for the neurosurgeon. The sterile - out-of-the-package, single-use probes - optimize patient safety and eliminate probe Neurosurgical applications Determine patency of parent and branching vessels after aneurysm clipping Assess completeness of aneurysm clipping Locate feeder artery in AVMs Locate major venous sinuses Confirm patency of major venous sinuses Confirm patency of microvascular anastamoses Localize vessels noted on angiogram Neurosurgeons appreciate many benefits of the VTI Microsurgical Doppler System ■ Real-time arterial and venous audio feedback immediately confirms results of surgical interventions ■ Always ready-to-use, sterile probes ■ High operating frequency provides tightly focused signal ■ Bayonette style probe facilitates use under microscope ■ Miniature probe tip provides high degree of precision with- out obscuring field of view ■ Reduces the need for intraoperative angiograms - saves During intracranial vascular Doppler resulted Firsching, et al.. Minim Invasive transceiver unit delivers a tightly focused signal, making the unit provides loud and clear portrayals of arterial and venous blood flow during neurosurgical procedures. During intracranial aneurysm vascular Doppler confirms the results of surgical intervention and helps save time and money intraoperative angiograms. VTTs neurosurgical probe is designed It incorporates a bayonette shaped handle and a miniature tip making it ideal for use under a microscope, without obscuring the surgical 12 Murphy Drive, Nashua, NH 03062 Toll Free: 800.550.0856 Outside USA: 603.594.9700 Fax: 603.594.0092 www. vti-online.com E-maii: [email protected]
