Abstract: The invention relates to a device (10) for closing a perforation (21) in a wall (2), the closing device (10) having closing means (11) comprising: a central portion (14), a first end (12) having a first hooking means (12?) and a second end (13) having a second hooking means (13?), the two ends (12,13) being arranged on either side of the central portion (14), the closing means (11) being made of a shape memory material and having a structure allowing a variation in the relative position of the hooking means (12?, 13?) with respect to one another, depending on the state of compression of the central portion (14).

Abstract: A cannula for the circulation of a fluid in an artery, includes a main lumen conveying a volume of fluid towards a first distal end; an accessory lumen including at least one inner portion arranged inside the main lumen, including: a proximal end situated downstream from the proximal end of the main lumen so as to capture a fraction of the flow of fluid entering the main lumen; a bent portion modifying the direction of flow of the fluid flow captured by the accessory lumen with respect to the direction of flow of the fluid emerging from the first end; a second distal end situated upstream from the first distal end of the main lumen, emerging on a side opening of the cannula so as to direct the captured fraction of liquid in the modified direction of flow.

Abstract: The invention relates to a cannula (1) for injecting a fluid (F1) into a body cavity (5), comprising: a main lumen (LP) for the fluid to flow in a first direction; an accessory reperfusion lumen (LA) comprising an outlet (20?) for discharging the fluid in a second direction; and a device for positioning the cannula in the cavity, the device comprising a stop (41) which can move along an auxiliary lumen (LX) and be deployed in the cavity in order to lock the cannula in position in the cavity, the outlet (30?) of the auxiliary lumen being arranged at a distance (d) from the outlet (20?) of the accessory reperfusion lumen such that when the cannula is locked in position in the cavity, the outlet (20?) of the accessory reperfusion lumen (LA) is oriented in the cavity such that the collected fluid is discharged in the second direction.
