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.

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.

Substance delivering spacer devices may comprise expandable reservoirs that are implantable in paranasal sinuses and other cavities, openings and passageways of the body to maintain patency and to provide sustained local delivery of a therapeutic or diagnostic substance. Delivery apparatus including elongate tubular members as well as shapeable distal portions and atraumatic tips are provided. Also provided are sinus penetrator devices and systems for performing ethmoidotomy procedures or for creating other openings in the walls of paranasal sinuses or other anatomical structures.

A method for treating ethmoid disease in human or non-human animal subjects includes inserting a sheath containing an implantable device having an expandable member. The sheath is removed from the implantable device causing the expandable member to expand, allowing for stability of the implantable device in the subject. Stenting, spacing, draining, ventilating and/or delivering drugs and other therapeutic or diagnostic substances to desired locations within the bodies of human or non-human animal subjects may also be involved.
