Definitions
- Aneurysms are usually treated before rupture occurs. Two surgical operations can be performed:
- the probes are divided into one or more groups of probes, the probes of each group being fixed at regular intervals around the stent on the same respective section of the stent; the sensor of each of the plurality of probes is a sensor; directional, its sensitivity being maximum for the pressures exerted perpendicular to its measuring surface,
- each probe comprising: a sensor for making a pressure measurement, and
- the aneurysm 12 as shown comprises a soft blood clot, or thrombus 16, extending from the arterial wall 14 to the center of the aneurysm 12.
- the portion of the thrombus 16 in contact with circulating blood (represented by the arrow 17) often forms a film, or intemna 18.
- the stent 20 shown in FIG. 2 is for excluding the aneurysm 12 from the circulating blood 17.
- the stent 20 comprises a tubular mesh 22 embedded in a biocompatible blood-tight extensible fabric or film 24 such as an elastomer .
- the assembly of the mesh 22 and the film 24 therefore forms a tubular envelope 22, 24 of the stent 20.
- the mesh 22 is made of stainless steel or an alloy having spring properties, so that the stent 20 is self-expanding. Such a stent is commonly referred to as "stent".
- the stent 20 is capable of spontaneously deforming from a compressed state, in this case a small diameter, to an expanded state, in which it has a larger diameter, this expanded state constituting its state of rest. Due to its elasticity, the stent 20 is intended, once laid, to be applied against the inner surface of the artery 10 on each side of the aneurysm 12, thereby forming an inner sheath.
- the voltage delivered by the sensor 28 is introduced into a low noise amplifier 30 in order to shape the analog signal.
- the low noise amplifier 30 comprises an instrumentation amplifier (not shown) having a higher common mode rejection ratio of preferably 80, and a low pass filter (also not shown) whose cutoff frequency is selected to to be able to recover the fundamental frequency of the signal but also enough harmonics to recover the systolic pressure. Indeed, it has been noticed that a lower rejection rate causes the presence of noise.
- step 160 of locating local maxima consists in determining the position along the flow direction XX 'of a slice at risk of the aneurysm perpendicular to this direction X-X '.
- the inventors have noticed that the weakened zones of the arterial wall 14 depended on the spatial geometry of the latter and were generally concentrated in rings around the flow direction X-X '. This is because, in particular, the endoleaks generate an overpressure not only at the point where they appear, but also, to a lesser extent, all around the flow direction X-X '.
- each wafer corresponds to a weakened zone of the aneurysm 12.
- two wafers have been determined, referenced A and B.
- the height of these wafers corresponds substantially to the size of the wafer. that each probe 26 presents along the stent, when the probe is fixed.
- the effectiveness of the stent once placed is not sensitive to the angular orientation of the stent around the direction of flow X-X ', since the probes 26 are evenly distributed around this direction. This greatly facilitates the placement of the stent which may have any angular orientation.
