EVAR (Endovascular Aneurysm Repair) is a minimally invasive procedure used to repair an abdominal aortic aneurysm (AAA) — a dangerous ballooning or weakening of the body's main artery, the aorta.

Instead of making a large abdominal incision like traditional open surgery, EVAR is performed from inside the blood vessel using catheters, guidewires, and a fabric-covered metal stent graft delivered through arteries in the groin.

Cholecystectomy Digital Module

A guided, interactive, patient-to-professional digital experience that explains gallbladder disease, prepares the patient, maps the operation step by step, and connects anatomy, workflow, devices, risks, and recovery into one usable module.

A cholecystectomy is the surgical removal of the gallbladder, most commonly done laparoscopically for symptomatic gallstones, cholecystitis, or related biliary disease. Laparoscopic surgery is the usual approach, while open surgery may be needed in more difficult or converted cases. Safe identification of the cystic duct and cystic artery using the Critical View of Safety is a core principle in modern cholecystectomy.  

  • This module should do four things at once:

    1. Educate the patient in plain language

    2. Support the surgeon and care team with structured workflow logic

    3. Map devices, supplies, and pharma to each phase of the case

    4. Create a reusable LDS digital product for web, app, LMS, and sales enablement.
