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: The dressing product comprises a metal alginate fibre core (1) surrounded by a supporting sheath (2) of a structure permeable to biological fluid and biocompatible with the wound. The core (1) and sheath (2) both extend into a continuous layer of alginate fibres and provide drainage slots (7, 8) between each other.

Abstract: A core (1), in the form of a cylindrical pack, of a dressing is surrounded by a sleeve (2, 3) for holding the mechanical structure of the core. The sleeve (2), which may be comprised of threads (2, 3), is permeable to biological fluid of wounds and is biologically compatible with wounds. The dressing is very suitable for deep wounds, from which it can easily be removed.

Abstract: The dressing for a chronic wound with biological liquid, comprises a matrix of calcium alginate associated with at least one alginate of a multivalent metal, with the exception of magnesium. The multivalent metal alginate is produced from sodium alginate which is extruded through a die disposed in a coagulation bath of a soluble salt solution of the multivalent metal. The multivalent metal alginate is associated with the calcium alginate matrix by means of a textile technique.

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.
