Pre-Sure®
Our patient-specific Pre-Sure models allow surgeons to plan and rehearse complex procedures on 3D-printed replicas and enter the OR with clarity. Each model is built directly from a patient’s CT or MRI data with materials that realistically mimic soft tissue making it an ideal rehearsal tool for complex, irregular anatomy and high-stakes cases where precision matters most.

The Pre-Sure Advantage
Experience True Realism
Viscoelastic, anatomical models built directly from patient imaging data deliver lifelike tissue response, tactile feedback, and realistic resistance so surgeons can rehearse with confidence before entering the OR.
Limit Costs in the OR
Rehearsing in advance reduces uncertainty, streamlines intraoperative decision-making, and helps optimize operative time and overall resource utilization.
Rehearse without Patient Risk
Cut, suture, and clamp on a fully operable, patient-specific replica — rehearse the complex portion of a surgery without risk to the patient.
Plan for Unique Challenges
Use real instruments on a precise physical model to plan the surgical approach, anticipate irregular anatomy, and refine technique before the case begins.
FDA Cleared
Pre-Sure® models are FDA-cleared Class II diagnostic medical devices for patient-specific preoperative rehearsal, providing confidence in quality, safety, and regulatory compliance.

Testimonials
Dr. Dipen Parekh
UHealth
“The test run showed me what to expect when I conducted the actual surgery. This may be a good simulation tool for patients who have a complex anatomy, such as an enlarged prostate or a median lobe, and require surgery.”

“If you’re going to run in a race, you don’t just do it. You practice. It’s the same concept with this technology.” From an educational standpoint, these models could help bridge the learning gap and boost confidence.”

Dr. Richard Link
BCM
“We have developed a patient-specific pre-surgical simulation protocol for robot-assisted laparoscopic partial nephrectomy (RALPN). We demonstrated construct validity and provided accurate representation of enucleation time and resected tissue volume. This simulation platform can assist in surgical decision-making, provide preoperative rehearsals, and improve surgical training.”
