AEDTH
Alexandria Endovascular Digital Twin Hub
Fabrication playbook AEDTH-PB-001, revision B, September 2026. Seven families share one digital thread, one connector standard and one hardware cell. The cell serves Smouha first. It does not treat a patient, and it does not own the institute’s patents.
Training and R&D fixtures inside the hospital. Not EDA-registered implants. Not sterile operating-room guides. The photographs are the target class in the playbook. They were not poured at Smouha.
Seven fabrication families
Do not invent a process for every model. Stand the cell up, then open families in the order the playbook sets: vessels first, simulators next, showcase last.
F1
Hollow vascular
Lost-core platinum silicone, CS-001 ports, Plate S, M or L.
F2
Endoscopy
Soft cast on a soluble core, a rigid shell, and a cassette for the lesion.
F3
Solid anatomy
Elastic print for day-one teaching, or a silicone cast when the feel matters.
F4
Hydrogel organs
Recipe H1 PVA cryogel, made that week. Recipe H2 is not a line.
F5
Puncture pads
A pumped vessel under a soft overlay. The vessel is the cheap cartridge.
F6
Flow bench
Buy the 220 V driver. Build the loop, the reservoir and the taps.
F7
Accessories
Acrylic plates and four CS-001 hose sizes. Never a printed Luer.
Family F3 has no pictured SKU in this release. A solid heart for teaching or family explanation stays on the planning lines already in the catalogue. Imaging still starts from a research PACS node, never the diagnostic station.
Months 2–6 · year 1
Vascular cell
The first fixtures the playbook names. Offered inside Smouha as training and R&D, not as devices for sale.
AEDTH-F1-PCIYear 1 offer2-D coronary PCI plate
لوح شرايين تاجية ثنائي البعد
A flat teaching lumen on Plate S: clear cover, white base, two CS-064 ports. The first SKU in the playbook, because it teaches acrylic before any dip-coat.
AEDTH-F1-NVYear 1 offerNeurovascular cassette
كاسيت وعائي عصبي
Circle of Willis plus one aneurysm, lost-core platinum silicone on Plate S. A new aneurysm is a cassette, not a new process.
AEDTH-F1-AOYear 1 offerAortic-arch module
وحدة قوس الأبهر
Type I arch first, then Type II and III, with CS-001 barb ports on Plate S or M. The arch stays with the thoracic module at plane P-ARCH.
- AEDTH-F1-IFYear 1 offer
Iliac–femoral module with stenosis cassette
وحدة حرقفي فخذي مع كاسيت تضيق
Runoff anatomy on the CS-001 grid, with one 40–60 mm stenosis cassette that recasts overnight and snaps in.
No target photograph in the playbook. Still one of the first ten SKUs.
AEDTH-F1-FBYear 1 offerFull-body arterial circuit
دائرة شريانية لكامل الجسم
Neuro, arch and iliac modules clipped together on Plate L and pumped. Four modules become the circuit; nobody glues a vessel to the plate.
AEDTH-CS-001Year 1 offerCS-001 multi-barb coupler family
عائلة وصلات CS-001
Four hose sizes only: CS-032, CS-048, CS-064, CS-095. If a lumen does not match, print a reducer sleeve. Never draw a one-off barb.
Months 6–12 · roadmap
Simulators
Opened only after the vascular cell stands. Not an invoice line yet.
AEDTH-F5-RARoadmap · year 2Radial puncture pad
وسادة بزل كعبري
A pumped CS-032 or CS-048 vessel under an Ecoflex overlay, 2–5 mm deep. The vessel is a cheap cartridge, not the pad.
AEDTH-F2-BRRoadmap · year 2Bronchoscopy trainer
مدرب تنظير القصبات
Airway to generation 5, then 6–7, in an acrylic thorax box. The Smouha scope has to reach the generation written on the label.
AEDTH-F2-URRoadmap · year 2Ureteroscopy trainer and stone kit
مدرب تنظير الحالب وطقم حصوات
Kidney, ureter and bladder with a two-stone kit. Swap-in stones sit in a cassette pocket.
AEDTH-F6Roadmap · year 2Pulsatile loop on a bought driver
حلقة نبضية على مضخة مشتراة
Buy a 0.2–2 L/min driver, 220 V 50 Hz. Build only the reservoir, CS-001 plumbing, compliance cylinder and pressure taps. Do not design a piston pump in month one.
Months 12–18 · roadmap
Showcase
ERCP, the TAVR cassette and the hydrogel liver. Do not start acrylamide, and do not call the root a sizing certificate.
AEDTH-F2-ERRoadmap · year 3ERCP path
مسار تصوير البنكرياس والقنوات
Stomach, duodenum and biliary tree on Plate M. ESD, if it is ever claimed, uses a refrigerated biological cassette. Do not print mucosa.
AEDTH-F1-TVRoadmap · year 3TAVR root cassette
كاسيت جذر لاستبدال الصمام
A replaceable valve in an acrylic box. Two healthy and two calcified leaflets are a phase-2 extra, not the first pour.
AEDTH-F4-LVRoadmap · year 3Hydrogel liver, Recipe H1
كبد هلامي — الوصفة H1
PVA cryogel, 10–12%, three freeze–thaw cycles. Made to order each week. Recipe H2 (acrylamide) is not this SKU.
The rest of the house
47 AEDTH lines run from year 1 to year 10, including patient-specific planning models that are not fixtures in PB-001. A roadmap line is not a clearance. The cell that would make them is drawn as a 25 × 5 m bay, not the deck’s 400–600 m².
