Abstract: The invention relates to an implantable surgical ring (1) designed to be closed on itself to form a closed loop (2) having an extension medium axis (XX?) for tightening a biological organ (3), wherein said ring (1) includes at least a first and a second ring tightening chamber (12, 13) attached to each other designed to contain a filling fluid for tightening said biological organ (3), said first and second tightening chambers being stepped along the extension medium axis (XX?), said ring being characterized in that the first and second tightening chambers (12, 13) include between them a material-free clearance area (20), in which the wall of the biological organ (3) may move without contacting the ring (1), in order to tighten said biological organ (3) at the level of at least two axially-separated contact areas (14A, 14B).

Abstract: The invention relates to an implantable medical device for injecting and/or collecting fluid substance into and/or from a human or animal organism, said device comprising a casing (6) whose wall (3) delimits a chamber and is pierced with at least a first access orifice (7) designed to allow a needle to pass through said wall (3), said device being characterized in that the first access orifice has a staged structure comprising: a guide portion designed to limit the angular clearance of the needle when said needle is engaged therein, and a flared intake portion that forms a continuation of the guide portion, so as to be able to cause the trajectory of the incoming needle to converge on the guide portion. Implantable medical devices.

Abstract: The invention relates to an implantable medical device (1) for injecting and/or collecting fluid substance into and/or from an organism and comprising a chamber (2) delimited by a wall (3) which has at least one pierceable portion (4) in the area of which said wall (3) can be pierced through in the direction of its thickness (e) by a needle (5), said device comprising means (10) for transverse compression of the pierceable portion (4), and also retention means (20) designed to oppose the buckling, towards the outside of the device, experienced by the pierceable portion (4) under the effect of the compression (F1).

Abstract: The invention relates to an implantable surgical ring (1) to be placed around a biological organ while winding around a mean extension axis (X-X?), said ring comprising at least one first bearing part (5) designed to bear against the biological organ and capable of extending inside the ring (1) along a substantially radial first direction (D1), said ring being characterized in that said first bearing part (5) is defined by a first membrane (10) provided with an asymmetrical bendable structure designed, when the first bearing part (5) expands along the first direction (D1), to cause an accompanying shift of at least part of the first membrane (10) from one side to the other of a plane (P1) medial to the first bearing part (5) and normal to the extension axis (X-X?). The invention can be used in gastroplastic rings.

Abstract: The invention relates to an implantable surgical ring (1) intended to close on itself around a mean extension axis in order to enable adjustment of the section through which a biological organ passes, said ring being characterized in that the same comprises at least one first and one second gripping bag (10, 11) that are tiered along the mean extension axis, are designed to be filled with filling fluid, and respectively have a first peak portion (12) and a second peak portion (13), and in that said first and second peak portions (12, 13) are separated by a separation area (14) including a retaining means (20) receding away from said first and second peak portions (12, 13) to limit the depth (P) to which the gripped biological organ can enter between said first and second peak portion.
