A method of dilating a first Eustachian tube (ET) and a second ET of a patient using a dilation catheter includes directing the dilation catheter into the mouth of the patient and advancing the dilation catheter into a first ET on one side of the patient's head while a proximal portion of the dilation catheter is disposed in the mouth of the patient. The method further includes expanding the expandable member to thereby dilate the first ET. The method may further include repositioning the dilation catheter relative to a second ET on another side of the patient's head and advancing the dilation catheter into the second ET while a proximal portion of the dilation catheter is disposed in the mouth of the patient. The method may further include expanding the expandable member to thereby dilate the second ET.

This document discusses, among other things, systems and methods for robotically assisted implantation of an implant in a patient. A system includes an external positioning unit configured to engage an elongate member of the implant, and a control console communicatively coupled to the external positioning unit. The control console may have a user interface that enables a user to input motion control instructions. The control console may generate a motion control signal, according to a specific motion control instruction, to control the external positioning unit to propel the implant into a target implant site. The system may be used to robotically control the delivery and positing of a cochlear implant during a hearing-preservation cochlear implant surgery.

An adjustable, earlobe repair instrument acts as a guide to the surgeon when excising and ensures symmetry. The device fits over and behind the split segment of the earlobe. It is then secured, and holds the tissue firmly, enabling the surgeon to make clear, precise, symmetrical cuts when removing the healed split or cleft segment prior to repair.

A system for dilating a Eustachian tube (ET) of a patient includes a guide member and a dilation catheter. The guide member includes a bent distal portion that is configured to provide access to an opening in the ET. The dilation catheter is slidable relative to the guide member. The dilation catheter includes a shaft, an expandable element, and an actuator. The expandable element is disposed at the distal portion of the shaft. The actuator includes a grasping portion and an actuating member. The expandable element is configured to transition to an expanded configuration in response to actuation of the actuating member. The grasping portion and actuating member are configured to be grasped in a single hand of an operator to enable the operator to advance the dilation catheter relative to the guide member and to transition the expandable element between expanded and unexpanded configurations with the single hand.

A surgical elevator includes an elevator body having an elevator body tip. The surgical elevator body and the elevator body tip are adapted to provide an elevation function during a surgery. A suction tube is integrated with the elevator body. The suction tube has a suction end. A control pad is attached to the suction tube. The control pad is adapted to position the suction end of the suction tube with respect to the elevator body tip of the elevator body so that, when no suction is required, the suction end of the suction tube is retracted behind the elevator body tip of the elevator body. When suction is required, the suction end of the suction tube is positioned in front of the elevator body tip of the elevator body.

A loading device is configured to load a ventilation tube into an inserter device. The loading device includes a main body and at least one protruding member extending from the main body and terminating at a loading tip. An elongated hollow body has a first end, a second end, an inner wall and an outer wall. The elongated hollow body surrounds the at least one protruding member such that at least a portion of an outer facing surface of the protruding member engages with an inner wall of the elongated hollow body. A ventilation tube engages with the loading tip of the protruding member and is at least partially located within the elongated hollow body.

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.

A dilation catheter system comprises a guide member, a dilation catheter, and an image sensor. The guide member includes a shaft comprising a distal end and a proximal end. The shaft further defines a longitudinal axis. The dilation catheter is movable relative to the guide catheter member and comprises an expandable dilator. The expandable dilator is sized to fit within one or both of a Eustachian tube or a passageway associated with a paranasal sinus. The image sensor is configured to provide visualization within anatomy of a patient. The image sensor is integral with the guide member.

Systems and methods for treating target tissues within the ears are disclosed. Systems include a tubular member defining a first lumen configured to deliver a solution containing a therapeutic agent into a space adjacent to a tympanic membrane in an ear canal; a support structure defining a second lumen separate from the first lumen; and an iontophoresis electrode disposed in the second lumen and configured to deliver a current to the solution to apply the therapeutic agent to the tympanic membrane.

A tympanostomy tube delivery device comprises a shaft assembly and a handpiece. All or a portion of the shaft assembly is selectively coupleable and removable from the handpiece. The handpiece includes a housing defining an opening that can receive a portion of the shaft assembly. The shaft assembly comprises a cannula, a piercer/dilator tube, a shield tube, and a pusher tube operable to translate relative to the cannula. The pressure equalization tube is positioned within the shield tube of the shaft assembly. The piercer/dilator tube and the shield tube are operable to pierce the tympanic membrane and dilate an opening formed therein. The pusher tube is operable to drive the pressure equalization tube out of the shield tube of the shaft assembly and into the opening formed in the tympanic membrane. Upon completion of the procedure, all or a portion of the shaft assembly may then be removed and replaced.
