Abstract: Such reinforcing medical device for a sutured tissue area, comprising a stapling line and a stapling circle, the device having a ring shape, so as to cover and reinforce the area along the stapling circle, wherein the ring comprises covering and reinforcing side means (4,6) so as to cover and reinforce portions of the stapling line extending beyond the stapling circle.

Abstract: The membrane is made of a polymeric material, characterized in that one (3) of its two faces at least has suppling and resorbability embossments (4).

Abstract: A parts fastener has a body having at one of its ends a flanged head projecting from the body. For that purpose the body evinces a central cavity communicating with the outside and includes at least a wall portion of which the inner side bounds part of the cavity, and which elastically deforms under an external force applied to the wall portion. The wall portion has, on its outer side, a projection which together with the head flange bounds a jaw by means of which the fastener may be inserted into the part to which it must be affixed. The projection opens on account of the deformation of the wall portion and frees the part and the fastener from each other. The device may also include means to cause the deforming force from the outside.

Abstract: A snap-fit device is provided for joining two parts of any shape together by fitting, perpendicularly to their junction surfaces, at least one element projecting from the junction surface of one of the parts, after slight deformation thereof, into a recess in the junction surface of the other part, and engagement of the projection element, by resilient return thereof, on a surface portion of the recess. Inside the device, a separation actuator is operable for separating the engagement projection from the portion on which it is engaged, against the resilient return force of the projection. The separation means is externally activated by a hydraulic or pneumatic pressure or a vacuum source.
