摘要： A tympanostomy tube delivery device comprises a body, a cannula extending distally from the body, and a cylindraceous member disposed within the cannula. The cylindraceous member comprises a tubular portion and a plurality of leaves positioned at the distal end of the tubular portion. The leaves are movable between a collapsed position and an expanded position. The cylindraceous member is slidable relative to the cannula to selectively expose the leaves relative to the open distal end of the cannula. A first leaf of the plurality of leaves has a sharp distal point configured to pierce a tympanic membrane and a longitudinally extending sharp edge. The cylindraceous member may be used to create and dilate a myringotomy incision in a tympanic membrane. The tympanostomy tube delivery device may then be used to deploy a tympanostomy tube through the myringotomy incision.

摘要： A tympanostomy tube delivery device comprises a shaft assembly, a pressure equalization tube, and a sensor. The shaft assembly comprises a cannula and a pusher operable to translate relative to the cannula. The pressure equalization tube is positioned within the shaft assembly. The pusher is operable to drive the pressure equalization tube out of the shaft assembly. The sensor is operable to detect a physical parameter associated with engagement between the distal end of the shaft assembly and a tympanic membrane. A controller may activate a feedback device to inform an operator that the distal end of the shaft assembly has achieved suitable apposition with the tympanic membrane, based on information from the sensor.

摘要： The invention is a tympanic membrane pressure equalization tube. The tube has a distal end and a proximal end and a tube lumen. A medial flange is located at the distal end of the tube and has 2 or more retention elements and a space between each retention element. A lateral flange is located at the proximal end of the tube. The outside diameter of the medial flange is greater than the outside diameter of the lateral flange and the diameter of the medial flange is between about 2.0 and 5.0 mm and the diameter of the lateral flange is between about 1.75 mm and 4.0 mm.

摘要： A tympanostomy tube delivery device comprises a drive assembly and a force limiting shaft assembly. The shaft assembly comprises a cannula and a piercer operable to translate relative to the cannula so as to pierce the tympanic membrane of a patient. The piercer is mechanically coupled with the drive assembly such that actuation of the drive assembly causes translation of the piercer relative to the cannula. The piercer is mechanically coupled with the drive assembly by a clutch. The clutch is resiliently biased to couple the piercer with the drive assembly. The clutch is configured to uncouple the piercer from the drive assembly in response to a threshold force being imposed upon the piercer so as to inhibit translation of piercer relative to the cannula.

摘要： An instrument comprises a shaft assembly, a handpiece body, and a drive assembly. The shaft assembly comprises a plurality of coaxially arranged shafts and a tympanostomy tube. The shaft assembly further includes a flexible section. The shaft assembly extends distally from the handpiece body. The drive assembly is operable to drive the shafts of the shaft assembly in a predetermined sequence to deploy the tympanostomy tube. One or more of the shafts are configured to translate along the flexible section of the shaft assembly as a part of the predetermined sequence to deploy the tympanostomy tube.

摘要： An instrument comprises a handpiece, a boss member, a cylindraceous cam body, a linearly movable member, a cam follower, and a braking member. The cam body is rotatably supported in the handpiece and includes an exterior cam feature. The cam follower couples the linearly movable member with the cam feature of the cam body. The cam feature and the cam follower cooperatively drive the linearly movable member linearly in response to rotation of the cam body within the handpiece. The braking member extends about at least a portion of the exterior of the cam body and is positioned to progressively engage the boss member as the cam body rotates within the handpiece. The braking member and the boss member thus cooperate to provide gradual braking of the cam body. The instrument is operable to deploy a pressure equalization tube in the tympanic membrane of a patient.
