A surgical access device comprises a seal assembly (51) having a plurality of part circular sealing members (55) each attached to a common ring (53) which is held within the device about its longitudinal axis. In use, the sealing members are located radially inwards of the ring in a stacked relationship. When not within the device, the sealing members are movable from a position radially outwards of the ring to a position radially inwards of the ring. A seal core comprises the seal assembly and a protective member which, in use, is located on the proximal side of the seal assembly. A method of assembling the surgical access device is also provided.
A surgical access device comprising a seal assembly comprising a plurality of part circular sealing members each attached to a common ring which is held within the device about its longitudinal axis and with the sealing members being located radially inwards of the ring in a stacked relationship, characterised in that the seal assembly comprises a single sheet of flexible material which may be arranged in a single plane with the part circular sealing members in a non-overlapping relationship and in that the sealing members are foldable, when not within the device, from a position radially outwards of the ring to a position radially inwards of the ring.
A device according to claim, wherein the connection is integral with the seal assembly.
A method of assembling a surgical access device having a seal assembly comprising a plurality of part circular sealing members each connected to a common support ring, the support ring being held within the device about its longitudinal axis, the method comprising the step of moving the sealing members from a position radially outwards of the ring to a position radially inwards of the ring, so that said sealing members are in a stacked relationship, characterised in that the seal assembly comprises a single sheet of flexible material which may be arranged in a single plane with the part circular sealing members in a non-overlapping relationship and in that the sealing members are foldable, when not within the device, from a position radially outwards of the ring to a position radially inwards of the ring.
