Patent ID: 8377064

Claim:
A device for dissecting the subantral membrane from the floor of the maxillary sinus, the device comprising: a handle; at least one part extending from the handle, the at least one part comprising an elongate support element having an upper distal end and defining a longitudinal axis, wherein the at least one part is rotatably coupled to the handle such that the elongate support element is adapted to be axially rotatable about its longitudinal axis by fingers of a user while the handle remains fixed in space and within a hand of the user; and a thin member realized from a polymeric material that extends from the distal end of the support element, the thin member having first and second peripheral regions disposed opposite each other, the first peripheral region joined to or integrally formed with the distal end of the support element, and the second peripheral region defining a thin blade-like section for dissecting the subantral membrane from the floor of the maxillary sinus, said blade-like section having a lower surface that is angled downward and away from said upper distal end of said support element such that said lower surface of said blade-like section and said longitudinal axis together define an acute angle.
