Development of US based device for intracranial ventriculostomy

The aim of this project is to create an ultrasound-guided drainage tube that is designed specifically for the procedure. Exploratory work has already been carried out in a very short research project and in two MEng projects which provide background and a starting point for the PhD.The envisaged device will not only make the procedure much easier but might facilitate it being done bedside, to make it much more time and economically efficient and easier for the patient. Other usage ideas are in place which can reduce the need for further imaging for those patients with an EVD in place in case the tube is obstructed, which is not uncommon.The ventriculostomy procedure is part of daily neurosurgical practice. According to a UK study, there were nearly 500 EVDs inserted in a specific six-month period. This does not include permanent shunt (drain) insertion, totalling a further 3000 shunts per year, approximately, according to the UK shunt registry. The global EVD market size was valued at USD 5.3 billion in 2019 and is expected to expand at a compound annual growth rate (CAGR) of 7.6% between 2020 and 2027.There is evidence supporting the use of image guidance during tube insertion to improve accuracy and avoid misplaced catheters. However, neurosurgeons might be reluctant to use image guidance to avoid time delays or because of their lack of experience with using ultrasound. Designing an easy-to-use, specific and efficient ultrasound imaging tool with a seamless user experience would therefore be of added value to the neurosurgical practice.Current activity can be divided into image-guided solution providers and tube (shunt) manufacturers. Neuro-navigation manufacturers includes Stealth and Brainlab and ultrasound manufacturers such as BK Medical. Shunt manufacturers are also relevant, if the new design is configures as an ultrasound imaging device integrated with the drainage tube. There are many relevant manufacturers including but not limited to Medtronic and Stryker.
