Cutting-edge medical device software


highest validated accuracy in device deployment simulation


Import patient scans

Import patient imaging files into the PreSize® Neurovascular software. PreSize® automatically creates an accurate 3D model of the patient’s vessel tree and centerline to explore.


Select optimal positioning

PreSize® calculates and visualises a best-fit virtual device size for the optimal selected position in the specific anatomy, based on the instructions for use of the physical devices.  


Rehearse alternative scenarios

Compare different device makes and sizes, interacting with the 3D model in real-time. Virtual rehearsal is complete when satisfied with the dimensions and placement of the implant. The actual procedure can then begin. 


PreSize's® segmentation has worked very well. There's a branch coming out from the aneurysm sac that at first glance you could have thought was over incorporated, but was in fact the true anatomy. PreSize® can cope with complex cases and is very straightforward to use.

PreSize® immediately attracted my attention; I realised how this groundbreaking technology could reduce risk and provide benefits for patients like me. The technology allows me to ‘visualise’ the proposed intervention and participate in the decisions and choices about what matters most to me.  It personalises my care by offering a visual tool to facilitate discussion about the risks, benefits and options with my clinician.
