Patient-specific digital twin

A patient-specific digital twin is a digital replica of a patient’s organ, extracted from pre-operative imaging. It has not only the same shape, but also similar biomechanical properties as the actual organ.

This digital twin is used to simulate accurately devices implantation, taking into account how devices interact with the anatomy.​

PlanOp™ Vascular

Thanks to PrediSurge unique digital twin technology, design your custom made stent-graft* with even more accuracy for short intervention time.

PlanOpᵀᴹ Vascular takes into consideration the interactions between the endograft and the patient’s anatomy, assisting physicians in evaluating the risk of complications and adapting their intervention strategy accordingly*.

An Endoleaks Risk Index (ERI) for standard EVAR*

Endoleak risk Index
Preliminary results suggest digital twin technology could help physician to determine risk of type IA endoleak

For standard EVAR, digital twin technology may help the physician to evaluate potential risk of complications*.

In particular, the proximal apposition of the endograft can be analyzed on the intervention simulation. An Endoleak Risk Index has been developed to characterize the quality of this apposition.

EnduSim I¹ study shows strong correlation between high ERI and type IA endoleaks.

A right fenestration – ostium alignment for complex EVAR*

Growing scientific evidence shows that digital twin technology is both safe and accurate for custom-made endograft designs

For complex EVAR, check with PlanOp that the custom endograft design is a perfect fit for your patient. Adjust fenestration position according to simulation and avoid misalignment issue on the day of the procedure*.

Why PlanOp™ Vascular?

Accurate simulation

Accurate simulations for short interventions times*

Right fenestration – Ostium alignment
  • In tortuous anatomies, not taking into account the interaction between the custom made endograft and the aorta can lead to significant fenestrations malposition.
  • As the interactions between the custom made endograft and the aorta are taken into account, PlanOp ® anticipates fenestration misalignment.
  • PlanOp® computes fenestrations positions iteratively, until the right alignment with the corresponding ostia is obtained;
  • Prospective use of PlanOp for fenestration positioning in custom made endograft results in median catheterization time as low as 60 sec​³.

Accurate simulation

Digital twin technology could help physician to assess the risk of complications*

Digital rehearsal of the intervention
  • Virtual tests of different devices designs & landing zones
  • Oversizing: Interactions between devices taken into account
  • Assessment of the stent-graft apposition on the simulation could help the physician to avoid type Ia endoleak
