Abstract:
1. An attachment device for anchoring to tissue of a patient, the attachment device comprising: (a) at least one body element provided with a base surface for overlying and contacting said tissue, the body element comprising an elongated rod defining a rotation axis extending longitudinally through the rod; and (b) an anchoring portion mounted on the rod and comprising a pair of clip bodies being rotatable relative to the rod and one another around the rotation axis, wherein the anchoring portion comprises: wherein the first and second mounting portions are rotatably mounted on the rod such that the first and second clip bodies are rotatable relative to each other around the rotation axis between an open position of the anchoring portion in which the anchoring portion is inoperative and a closed position of the anchoring portion for anchoring the device to the tissue of a patient, wherein the first and second clip bodies are configured such that rotating the first and second operating portions toward each other in opposite directions is effective to move the first and second clip bodies from the open position to the closed position; wherein in the open position of the anchoring portion: the first operating portion provides a first shielding portion which shields at least the pointed end part of the second piercing member against inadvertent contact with another object, and the second operating portion provides a second shielding portion which shields at least the pointed end part of the first piercing member against inadvertent contact with another object; and wherein in the closed position of the anchoring portion in use: the first and second locking portions inter-lock with each other to resist rotation of the first and second clip bodies toward the open position; wherein the first and second clip bodies are configured such that rotating the clip bodies from the open position to the closed position is effective to rotate the first and second piercing members in opposing directions away from the second and first shielding portions, respectively, toward each other until the piercing members are in contact with each other, and to rotate the first and second locking portions in opposing directions toward each other until the locking portions engage and inter-lock with each other.
