An apparatus comprising an elongate probe member having proximal and distal extremities for use with a suction source to treat a portion of a wall forming a cavity in a body having a natural body opening for accessing the cavity. The elongate probe member has a length so that when the distal extremity is in the vicinity of the portion of the wall the proximal extremity is outside of the body. The distal extremity of the elongate probe member has an outer surface and is provided with at least one recess opening onto the outer surface and an internal passageway communicating with the recess. When the suction source is coupled to the apparatus a suction is created in the recess by means of the passageway to draw the portion of the wall into the recess. A hollow needle is slidably disposed in the elongate probe member and has a distal end portion. The needle is actuatable from outside the body for movement from a retracted position in which the distal end portion of the needle is out of the recess and an extended position in which the distal end portion of the needle extends into the recess. The needle can be extended into the portion of the wall drawn into the recess so as to introduce a material into the portion of the wall and form an implant in the portion of the wall.
