Trandomed Neurovascular Intervention Model: High-Fidelity Simulation for Neurological Interventional Training and Device Testing

Overview and Core Application Scenarios
The high-precision neurovascular intervention model independently developed by Trandomed is professionally engineered for comprehensive performance testing, intuitive functional demonstration, and standardized clinical training of mainstream neurological interventional devices. It fully adapts to all commonly used neurointerventional instruments on the market, including micro guidewires, diagnostic and therapeutic catheters, filter stents, detachable coils, and intracranial vascular stents. As a high-standard, repeatable simulation platform, it effectively meets the diverse demands of medical device manufacturers for pre-market verification, academic promotion and product function display in industry exhibitions and clinical seminars. Meanwhile, it provides a zero-risk, high-fidelity practicing solution for neurologists and interventional physicians at all skill levels to master complex intracranial vascular operations. It greatly compensates for the insufficient standardized training system and the lack of intuitive practice carriers in current neurointerventional clinical practice, helping trainees steadily polish operational skills without endangering patient safety.

Complete and Optimized Vascular Anatomical Structure
This neurovascular model adopts an integrated full-path vascular design, completely reproducing the complete vascular system required for routine and complex neurointerventional surgeries. It precisely restores core intracranial anatomical structures, including the anterior, middle and posterior cerebral arteries with preset aneurysm and stenosis lesions, basilar artery and intact Willis circle, which are critical for intracranial intervention diagnosis and treatment. Furthermore, it covers the entire systemic access pathway, including bilateral vertebral arteries, bilateral common carotid arteries, thoracic aorta, iliac arteries and femoral arteries, truly simulating the full surgical route from peripheral puncture and vascular navigation to precise intracranial lesion intervention.
To enhance clinical simulation authenticity and restore real surgical difficulty, the model features an optimized internal carotid artery siphon segment, equipped with two 180-degree bends and two 360-degree bends that highly restore the complex tortuous characteristics of human intracranial vessels. This unique structural design effectively replicates the real operational resistance, angle limitation and instrument maneuvering difficulties in authentic clinical scenarios, helping trainees greatly improve precise instrument control, angle adjustment and three-dimensional spatial judgment in narrow, curved lumens. In addition, the model supports replaceable middle cerebral artery and vertebral artery components, allowing flexible switching of different lesion modules to achieve iterative training for various complex vascular diseases and lesion conditions.

High-Fidelity Material Configuration and Diversified Selection
The entire model body is crafted from premium 40A high-transparency soft silicone, which perfectly simulates the elasticity, toughness and wall friction of human cerebral vessels and restores real vascular biomechanical feedback during instrument navigation and operation. The superior high light transmittance enables trainers and instructors to clearly observe the whole process of guidewire delivery, catheter advancement, balloon dilation and stent deployment inside the vessels in real time, realizing visualized, traceable and correctable standardized training. To satisfy different application scenarios such as long-term training, instrument testing and exhibition display, the model supports multiple material options such as transparent silicone, transparent resin and acrylic. It is worth noting that individual special materials may cause slight lumen deformation, and customers can consult professional teams for accurate parameter details before selection to match their actual usage demands.

Standardized Design and Personalized Customization Service
The overall design and technical indicators of the model strictly comply with the Guidelines for Registration Review of Intravascular Devices issued by the Medical Device Technical Evaluation Center of the National Medical Products Administration. It can be developed and optimized in full accordance with official regulatory requirements, providing reliable, standard and repeatable test data for the registration, performance evaluation and clinical verification of various intravascular interventional devices. Besides mature standardized products, Trandomed also provides exclusive personalized customization services for enterprises and medical institutions. The model can be tailored with exclusive vascular structures, lesion locations, stenosis degrees and aneurysm features based on customers’ clinical enhanced CT data or customized R&D and training needs, fully adapting to differentiated scenarios of hierarchical clinical skill training, academic research and innovative medical device testing.
