Abstract: The disclosure relates to a hemostatic device (1) comprising: -a hollow shaft (2) extending from a first end (4) to a second end (6), the shaft (2) comprising an inner channel (8) configured to be fluidically connected to a vacuum source, -a plurality of hollow ribs (10), a first end (9) of each rib (10) being fixed to the first end (4) of the shaft (2), each rib (10) comprising an inner channel (11) fluidically connected to the inner channel (8) of the shaft (2) and a plurality of holes (12) leading to the inner channel (11) of the respective rib (10), -a membrane (16) extending between the ribs (10) and configured to be placed so as to face, at least partially, a bleeding area of a natural body cavity, the plurality of holes (12) of each rib (10) being arranged so as to face the bleeding area to induce a negative pressure in the natural body cavity when a negative pressure is applied by the vacuum source, the induced negative pressure being configured so that the wall of the natural cavity is attracted to t

Abstract: The disclosure relates to a hemostatic device (1) comprising at least a first chamber (100) configured to be fluidically connected to a fluid source and a second chamber (200) configured to be fluidically connected to a vacuum source, wherein the hemostatic device comprises a first membrane (201) fluidically isolating the second chamber (200) from the first chamber (100) and a second membrane (202) configured to be placed so as to face, at least partially, a bleeding area of a natural body cavity, the second membrane (202) comprising a plurality of through holes (203) leading into the second chamber (200) and configured to induce a negative pressure in the natural body cavity when a negative pressure is applied in the second chamber (200) by the vacuum source, the induced negative pressure being configured so that the walls of the natural body cavity are attracted to the second membrane (202).

Abstract: This vascular stent graft (1) is formed of a tubular knitted textile structure, integrating within the meshes of said knitted textile structure at least one helical continuous weft yarn (3) extending all along the major dimension of the stent graft. Said at least one stent graft (3) is made of a shape memory alloy having previously been submitted to such an education, and in particular such a thermomechanical treatment that, at the human body temperature, said yarn gives the structure its tubular shape by superelasticity or shape memory effect.
