Abstract : After reviewing the bibliography concerning CAMI in general, CAMI and guidance systems applied to soft tissues, we will present three projects developed in our laboratory. Computer-assisted-pericardiocentesis (CASPER) is a guidance system based on a modeling of the pericardial effusion, thanks to preoperative 3-D data recording. The procedure requires an ultrasonic device and a needle, both connected to a 3-D localizer, and a computer. Validation on an experimental model, on an animal model, and the first clinical results are described in the second part. To keep the trajectory strictly aligned with the planned one during the puncture, we suggested using a semi-active system, a passive arm with dynamic constraint (PADyC). The development of a 6 DOF prototype in our laboratory and the pre-clinical experiment are described in the third part. The last part describes the methodology of a preoperative planning in minimally invasive cardiac surgery along with the first feasibility experiments.
