US Patent:

7455523, Nov 25, 2008

Filed:

Apr 15, 2005

Appl. No.:

11/107025

Inventors:

Daniel Lee Hendrickson - Golden CO, US
Raymond Lopez - Denver CO, US
William Younkes - Greenwood Village CO, US

Assignee:

Medical Simulation Corporation - Denver CO

International Classification:

G09B 23/28

US Classification:

434262, 434272

Abstract:

A portable medical simulation system and method employs an artificial patient with a built-in haptic interface device, with up to four carriages for engaging different diameter catheters. A catheter stabilizer between each carriage expands and contracts in an accordion fashion as the carriages move in relation to each other, preventing the catheter from bending and bowing. A contrast display visual effect derived from a particle emitter software tool simulates the release of radiopaque dye within a simulated vasculature system for display on a monitor. A computer software based system is used for generating haptic effects on the catheter through control signals passed to each of the carriage motors controlling translation movement of the catheter and magnetic particle brakes controlling rotational movement of the catheter.

Raymond Lopez - Denver CO, US
Christopher David Lee - Boulder CO, US
Brett Plumadore - Castle Rock CO, US

Assignee:

Medical Simulation Corporation - Denver CO

International Classification:

G09B 23/28

US Classification:

434267, 434262

Abstract:

A method, apparatus and system for simulating the release of radio opaque dye within a vasculature system. The method, apparatus and system include simulating a vessel tree of the vasculature system for display on a display device, activating a particle-based contrast software effect, and injecting a plurality of physics-based particles into a confined vessel space of said vessel tree. The method and apparatus may also include fading down over a period of time an opacity of each of the physics-based particles and opacifying a portion of a vessel wall.
