AEDTH

What the models look like

Segmentation first, then a lumen you can hold. The clear plates are catalogue examples of silicone vascular simulators. AEDTH’s own batches will carry a deviation note and a leak check. These photographs do not.

• 

  A demonstration segmentation, not a Smouha patient. The coronaries, sinuses of Valsalva, leaflets, aorta, ventricles, atrium and myocardium are separated before anyone prints a model. That is how a clinician sees the anatomy, checks whether a device can fit, and meets the difficult part of the case before the operating room.

• 

  The instrument meets the model, not the patient. This is an example of a silicone rehearsal model. It was not photographed at Smouha, and MEDRA does not sell a spine line.

• 

  A full-body arterial phantom: a lumen a device can track. Photograph from a silicone-simulator catalogue (Ningbo Trando). It shows the class of model AEDTH is building toward. It was not made at Smouha, and it is not a supplier selected for purchase.

• 

  Circle of Willis on a small pump. The bench is for rehearsal and for seeing flow. It is not a clinical measurement. Photograph from a silicone-simulator catalogue (Ningbo Trando). It shows the class of model AEDTH is building toward. It was not made at Smouha, and it is not a supplier selected for purchase.

• 

  A tortuous carotid path in a flat plate. This is the insert idea: one carrier, a lumen you can change. Photograph from a silicone-simulator catalogue (Ningbo Trando). It shows the class of model AEDTH is building toward. It was not made at Smouha, and it is not a supplier selected for purchase.

• 

  Coronary tree with a pump, and room for radial or femoral access. The lesion you swap is the consumable. Photograph from a silicone-simulator catalogue (Ningbo Trando). It shows the class of model AEDTH is building toward. It was not made at Smouha, and it is not a supplier selected for purchase.

• 

  A four-chamber heart in a clear tank, with arteries and veins. This is the shape of a structural planning model. Photograph from a silicone-simulator catalogue (Ningbo Trando). It shows the class of model AEDTH is building toward. It was not made at Smouha, and it is not a supplier selected for purchase.

• A custom splint is drawn on the scan before anything is printed. A jig follows the same order: design on the anatomy, then make the part. This clip is a public design example. It is not a MEDRA device and it is not for sale.

Ten sections

1. S1

   Imaging to design

   DICOM in, a watertight mesh and a deviation note out. Patient data stays here.

2. S2

   Silicone cast

   Lost-core phantoms. The casting cell is the product, not a printed elastomer.

3. S3

   Neurovascular

   Circle of Willis, aneurysm and stenosis inserts, clear lumens.

4. S4

   Coronary and structural

   Root, landing zone, detachable coronary lesions.

5. S5

   Paediatric and congenital

   One-to-one hearts for planning and for family explanation.

6. S6

   Aorta to periphery

   Large constructs. The route — build, modular, or outsource — is still open.

7. S7

   Haemodynamics

   Flow loop and datasets. Bench, not a clinical measurement.

8. S8

   Training theatre

   Booked days and competency sheets. Inserts are the consumable.

9. S9

   Quality system

   Records, holds, and the honesty rule: a roadmap is not a clearance.

10. S10

    Metrology

    Calipers, leak test, and later imaging overlay. The room stays at 22–26 °C.

34 catalogue lines sit in this house, from year 1 through year 10.
