It’s a no-brainer…image guidance is better than no guidance in neurosurgery.
Image-guided surgery is standard of care in neurosurgical operating rooms, but in the ICU and at bedside, we are still performing brain procedures with free hand techniques using only surface landmarks. As an educator of neurosurgical residents, I often tell my residents that good enough is not good enough. And when it comes to placing external ventricular drains, it is not even good enough.
It’s with this knowledge, that I became involved with Intravent to bring to market, technology that can help improve accuracy and decrease complications for these invasive bedside procedures. I am certain that by introducing neuronavigation into the ICU, we will expand the scope and breadth of neuro-critical care and provide our patients with better and earlier life-saving interventions.

Primum Non Nocere
First do no harm
The Hippocratic Oath, taken by thousands of incoming medical students each year, is one of many ethical codes adopted by national medical associations. Iatrogenic complications are, at times, an unfortunate consequence of invasive procedures. Those associated with External Ventricular Drain placement are not only common, they are at times devastating. Multiple technologies have been developed and adopted throughout different fields of medicine to improve patient safety but nothing designed specifically to combat this recognized problem. In the operating room there are multiple devices that allow for visualization and navigation and they are rapidly becoming pervasive throughout a majority of surgical specialties. In the ICU we are left with a methodology for External Ventricular Drain placement that is nearly identical to those practiced over a hundred years ago. I am excited to be a part of a company dedicated to bringing navigation and visualization to the bedside while providing the safety and precision that critically ill patients deserve.

inTRAvent is a real tipping point for economic, ergonomic, and easily accessible navigation for external ventricular catheter systems placement. The product has streamlined and simplified the workflow to allow state of the art ultrasound technology to be available in a ubiquitous manner, improving the neurosurgeon's performance. inTRAvent's SOLOPASS system will be the new standard of care in the future. It is an unparalleled resource with a high level of accuracy. I can't imagine going back!

Healthcare has entered an age of precision medicine, patient-specific treatment algorithms alongside robust national and international quality assurance initiatives. Now more than ever we have the knowledge and technology to deliver exceptional care while mitigating risk of patient harm.
inTRAvent is at the forefront of such efforts in the neurocritical care space. Placement of an external ventricular drain (EVD) is one of the foundational treatments offered in brain injury of any etiology. However, until SOLOPASS, it had limitations and carried risk. inTRAvent has created a remarkably intuitive and user-friendly device allowing accurate placement of EVD’s in a single attempt. Gone are the days of misplaced catheters and multiple attempts to place the catheter. The mitigation of risk by eliminating multiple passes and inaccurate targeting cannot be overstated. inTRAent’s SOLOPASS will revolutionize bedside brain instrumentation. The choice is clear: the time has come where practitioners insist on the same accuracy used in the operating room be brought to the bedside. inTRAvent makes that possible with SOLOPASS.
