Abstract

The present invention relates to an interventional procedure simulation system, comprising a control unit and an interface unit, said control unit communication with said interface unit to simulate handling of at least one instrument interfaced by said interface unit. The instrument is a self expanding tool inserted inside a simulated vessel and simulated with respect to a set value representing a stiffness of said vessel, a rest diameter of said self expanding tool, a vessel initial inner diameter and spring constant for said tool.

Claims

1. An interventional procedure simulation system, comprising a control unit and an interface unit, said control unit communicating with said interface unit to simulate handling of at least one instrument interfaced by said interface unit, wherein said instrument is a self expanding tool inserted inside a simulated vessel and simulated with respect to a set value representing an stiffness of said vessel, a rest diameter of said self expanding tool, a vessel initial inner diameter and spring constant for said tool.

2. The system of claim 1, wherein said instrument is a stent.

3. The system of claim 1, wherein said instrument is a distal protection device.

4. The system of claim 3, wherein said distal protection device comprises a substantially double cone attached at two ends to a wire, and covered by a sheath.

5. The system of claim 4, wherein a distal part of one cone is a net for simulating catching particles that can be set free during an intervention simulation.

6. A method of simulating in an interventional procedure simulation system, comprising a control unit and an interface unit, said control unit communicating with said interfaceunit to simulate handling of at least one instrument interfaced by said interface unit, the method comprising:

providing a said instrument as a self expanding tool inserted inside a simulated vessel, and

simulating said instrument with respect to a set value representing an stiffiess of

said vessel, a rest diameter of said self expanding tool, a vessel initial inner diameter and spring constant for said tool.
