| 摘要 |
<p>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.</p> |
