<p>An apparatus (21) comprising a flexible elongate member (31) having proximal and distal extremities (31a, 31b) and having a passageway (51) extending from the proximal extremity to the distal extremity. A handle (33) is coupled to the proximal extremity of the flexible elongate member for introducing the distal extremity of the flexible elongate member into a natural body opening of a body. The flexible elongate member has a length so that when the distal extremity is in the vicinity of a wall forming a cavity accessible from the opening the proximal extremity is outside of the body. A needle (61) is disposed in the passageway and is accessible from the proximal extremity of the flexible elongate member for movement from a retracted position disposed in the passegeway to an extended position disposed out of the passegeway for penetrating the wall. The needle has a distal end portion (61b) provided with at least one opening (71) and a passage (63) extends through the needle to the opening. A supply assembly (27) including at least one reservoir (92) of at least one nonaqueous solution capable of forming a nonbiodegradable solid in the body is coupled to the proximal extremity of the flexible elongate member for introducing the nonaqueous solution through the passage and the at least one opening in the needle into the wall. The nonbiodegradable solid forms from the nonaqueous solution in the wall to treat the wall.</p> |
