Physics-based models for catheter, guidewire and stent simulation.

For over 20 years, interventional methods have improved the outcomes of patients with cardiovascular disease or stroke. However, these procedures require an intricate combination of visual and tactile feedback and extensive training periods. An essential part of this training relates to the manipulation of diagnostic and therapeutic devices such as catheters, guidewires, or stents. In this paper, we propose a physics-based model of wire-like structures that can be used as a core representation for the real-time simulation of various devices. Our approach is computationally efficient, and physically realistic. A catheter/guidewire is simulated using a composite model, which can dynamically adapt its material properties to locally describe a combination of both devices. We also show that other devices, such as stents, can be modeled from the same core representation.
