Still under development, this device provides realistic hemodynamics with patient specific valve models. The user can interactively adjust chordae length while the system is in operation. The valve models can be surgically repaired and repair results can be evaluated both visually and using transesophageal and transthoracic echocardiography.
Based on patient data, the models consist of major arteries and veins with branches in the renal hilum, two tumours, and the ureter. Surface vasculature, fat and a replaceable fascia are optional features. Models can be either tissue-like silicone, or polyvinyl alcohol cryogel. Internal vascular models are also possible: contact us for details.
The NHVS was custom developed for researchers at Western University in London Canada. This system has functioning mitral and aortic valves and realistic left ventricular pressures.
This simulator provides bench top training for cardiac and spinal fluoroscopy applications. It combines a 40 cm C-arm model with wireless accelerometer devices, and sophisticated software for mimicking realistic fluoroscopy images.
Our mitral valve models include chordae tendinae and suturable papillary muscles. The valve material will hold sutures, and procedures like tissue resection, annuloplasty rings or neochordae can be performed. The valves can be loaded into our dynamic valve simulator to validate repair outcomes.
The LV+ was originally designed for simulating beating heart, apical access interventions. It has since evolved as a simulator for patient specific valve analysis, ICE ultrasound validation, and TEE trainer…among other applications.
