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

the control unit is programmed to simulate said instrument with respect to an initial set value representing a stiffness of said vessel, a rest expansion diameter of said self expanding tool, an initial inner diameter of said vessel and a 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 double cone attached at two ends to a wire.

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 an interventional procedure simulation system including 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, the method comprising:

providing said at least one instrument as a self expanding tool inserted inside a simulated vessel; and

simulating said at least one instrument with respect to a set value representing a stiffness of said simulated vessel, a rest diameter of said self expanding tool, an initial inner diameter of said simulated vessel and a spring constant for said self expanding tool.

7. An interventional procedure simulation system, comprising:

a control unit communicating with said interface unit to simulate handling of at least one instrument interfaced by said interface unit, wherein said at least one instrument is a self-expanding tool inserted inside a simulated vessel, and the control unit is programmed to simulate said instrument with respect to an initial set value representing an stiffness of said simulated vessel, a rest expanding diameter of said self-expanding tool, an initial inner diameter of said simulated vessel, and a spring constant for said self-expanding tool; and

an interface unit, said interface unit including a detecting member adapted to detect a thickness of said at least one instrument, and an optical sensor adapted to detect the presence of said at least one instrument in the interface unit,

wherein said control unit is further programmed to measure a longitudinal movement and a movement of rotation of said at least one instrument and providing a force-feedback in a longitudinal direction and in a direction of rotation of said at least one instrument according to a received force and torque.
