Neurovascular Intervention

“We recognise that not all neurovascular interventions can be displaced by robotic surgery due to the complexity of vascular and aneurysm anatomies, however this accomplishment does demonstrate promise for procedures to be performed like this in the future. The Contour device is positioned as an easy to use ‘one and done’ solution, which we believe makes this a very realistic application for robotic surgery, as Nitin Dange has clearly demonstrated.”

Study of 12,128 patients over 5 years showed automated AI measurement of visceral fat area on abdominal CT images predicts future heart attack or stroke risk better than overall weight or BMI

Coils have the potential to introduce undesirable point or localised forces on the aneurysm wall which can lead to an IAR. The incidence rate of IAR is low but the mortality rate associated with such complications remains high. Causes of IAR are likely multifactorial and may be related to characteristics of the aneurysm such as wall thickness or integrity as well as properties of the procedure such as catheter tip position. For example, it is possible that a very soft, small coil can perforate an aneurysm if deployed through a catheter tip that is pinned against an aneurysm wall (immediately apposed to the dome). IAR rates as reported in the literature have found no specific correlation related to coil type (framing, filling, finishing) and sequence. IAR rates are somewhat dependent on aneurysm location10, and size.

The UK-based startup Proximie, which has developed an augmented reality tool to save lives by allowing senior surgeons to virtually climb into any operation theatre across the globe, has seen a 430% increase in surgeries this year.
Since being founded by the NHS surgeon Dr Nadine Hachach-Haram in 2016, the startup has managed to attract 2,500 users across 300 hospitals and has had its tool used in over 7,000 surgeries.

Neurovascular intervention is an approach for the treatment of neurological disorders and neurovascular diseases that affects the central nervous system. It is also used for the treatment of associated blood vascular systems using minimally invasive procedures. Neurological medical devices have been broadly classified into Neuro-stimulation Devices, Interventional Devices, Cerebral Spinal Fluid (CSF) Management Devices and Neurosurgery Devices.

Basics of Neurovascular Intervention and Neurointerventional devices

Traditionally, stent-assisted coiling and balloon remodeling have been the primary endovascular treatments for wide-necked intracranial aneurysms with complex morphologies. PulseRider is an aneurysm neck reconstruction device that provides parent vessel protection for aneurysm coiling. The objective of this study was to report early postmarket results with the PulseRider device.

Sphenopalatine ganglion stimulation is safe for patients with acute ischaemic stroke 8–24 h after onset, who are ineligible for thrombolytic therapy. Although not reaching significance, the trial's results support that, among patients with imaging evidence of cortical involvement at presentation, sphenopalatine ganglion stimulation is likely to improve functional outcome.

The ANA™ thrombectomy system is a novel stroke thrombectomy device comprising a self-expanding funnel designed to reduce clot fragmentation by locally restricting flow while becoming as wide as the lodging artery.

Donald Ricci, president and Chief Executive Officer of Evac commented, “We have listened to the experts in the neuro field and developed an improved version that is smaller and easier to use. This will allow treatment for a wider range of aneurysms and shorten delivery times,” he continued, “The previous version showed exceptional outcome due to the eCLIPs implant’s ability to bridge the neck of the aneurysm and to create a flow diversion effect. This new and improved version retains these favourable characteristics and also allows eCLIPs to gain access to smaller and more distant vessels within the cerebral anatomy.”

During this course EMS providers will be introduced to LVO stroke, as well as a sample of stroke severity scales that are intended to accurately predict LVO stroke in the field. This course will also present how EMS providers can improve prehospital stroke screening, documentation, and communication with receiving stroke centers.

HPC is an aneurysm implant and Flow Diverter coating, which shall reduce the risk of thrombosis on the surface of stents. Due to the thrombogenic surface, platelet function-inhibiting drugs are needed to prevent in-stent thrombosis. The current solution of preventing platelet activation is the Dual Anti-Platelet Therapy (DAPT) consisting of Aspirin and Clopidogrel.

Aviceanna.AI has announced that its medical imaging artificial intelligence (AI) tool, CINA Head, has qualified for the new technology add-on payment (NTAP) recently approved by the Centers for Medicare and Medicaid Services (CMS).

A new case study reveals a link between COVID-19 and clotting in blood vessels in the brain that results in an increased risk of ischemic stroke. Five of the six cases included in the study suffered an ischemic stroke within 8-24 days of the onset of coronavirus symptoms. Early use of anticoagulants might help reduce the risk of blood clotting and stroke in patients with COVID-19.

After diabetes, Medtronic is looking to leverage AI through a distribution agreement with Viz.ai, which uses the technology to streamline stroke care.

Synchron has been awarded nearly AUD$1M ($990,000) in funding from the Medical Research Future Fund (MRFF), through MTPConnect, the Australian Government’s BioMedTech Horizons (BMTH) programme, to advance the commercialisation of Synchron’s Stentrode. Stentrode is a minimally-invasive brain-computer interface being designed to restore functional independence, including the ability to text message, for people with paralysis by facilitating control of external personal devices through thought alone, and without the need for open brain surgery.

Cerus Endovascular has announced that it has received CE mark approval for its CerusEndo MC 021 microcatheter, designed to allow physicians to access tortuous neurovasculature and deliver therapeutic devices to intended targets.

A novel tandem stent thrombectomy technique “seems to be a safe and effective” rescue treatment for acute large vessel occlusion (LVO) that is resistant to conventional attempts, concludes a study recently published in the Journal of NeuroInterventional Surgery.
