A device useful in dealing with perforations in blood vessels and heart, including a probe having a distal end, an actuation console to which the proximal end of the probe is connected. The probe includes three coaxial cylindrical tubes each having an even diameter, all being concentric at least in one section of the probe. One of those tubes, having the smallest diameter, is attached firmly to a sleeve at its distal end. Another one of these tubes, referred to as the enveloping tube is the one tube with largest diameter yet reaching distally not as far as the distal end of the intermediate tube. Between those two tubes, a third coaxial one, is an intermediate tube having a diameter size measuring between that of the smallest diameter tube and that of the enveloping tube. A free tubular space exists between the intermediate tube and the enveloping tube, another property of the intermediate tube is that it is always static longitudinally respective of the console. A collapsible balloon, toroidal when inflated, further characterized as being slidable along a distal portion of the intermediate tube, firmly attached to the end of the enveloping tube. A feed tube, not coaxial with the probe, occupies some of the free tubular space, running alongside the intermediate tube externally from the console and reaching the distal end of the enveloping tube to optionally feed the balloon. The sleeve is capable of shape shifting from conical state, basically to such a state that its diameter grows bigger at the expense of its length, upon compression when the inner tube is pulled back towards the console. Two kinetic energy storing elements one for applying a pull on the inner tube towards the console, and another one for pushing the enveloping tube towards the distal tip of the probe, and with it the balloon attached to it, and a device for feeding the balloon with gas or liquid through the feed tube in order to inflate it.Linvention concerne un dispositif servant à traiter des p
