An apparatus includes a rigid body, a flexible sealing element, a nozzle assembly, and an electrode. The rigid body defines a channel, a reservoir, and a vent path. The reservoir is in fluid communication with the channel. The vent path is in fluid communication with the reservoir. The reservoir is configured to provide spacing between the channel and the vent path. The sealing element is positioned distal to the rigid body. The nozzle assembly includes a nozzle head and a post. The post extends distally through the channel of the rigid body. The nozzle head projects distally from a distal end of the post. The electrode is disposed within the channel of the rigid body. The reservoir extends laterally from a longitudinal axis defined by the electrode.

Earplug assembly for iontophoresis system

Systems and methods are provided for sealing an ear canal for retaining a solution in the ear canal. Adhesive earplugs are provided through which the solution can be delivered, and which, following delivery, retain the fluid in the ear canal. The systems and methods may also be useful for delivering an anesthetizing solution to the ear canal of a human patient and for maintaining the solution therein for use with an iontophoresis system for anesthetizing the tympanic membrane.

Adhesive earplugs useful for sealing the ear canal

Systems and methods are provided for anesthetizing a tympanic membrane of an ear. The systems are personalizable to ensure proper anesthetizing solution administration. The systems and methods may also be useful for administering a solution to the ear canal of a human patient and for maintaining the solution therein.

Personalizable system and method for anesthetizing the tympanic membrane

Devices, instruments and tools for minimally invasive surgical procedures. Port devices and methods for hemostatically sealing and providing a port through a tissue wall that interfaces with a fluid containing chamber, by minimally invasive techniques. Assemblies, instruments and methods for minimally invasive access to and through a tissue wall that interfaces with a fluid containing chamber, and for visualizing same. Instruments, assemblies and methods for minimally invasive surgical procedures, including ablation.

Devices and methods for minimally-invasive surgical procedures

An instrument for treating a sinus cavity includes a cutter member, a rotatable member, and a fluid passage. The cutter member has a lumen extending therealong, and the rotatable member is received within the lumen. The rotatable member has a helical blade projecting from a distal end portion. The cutter member is configured to translate relative to the rotatable member. Thereby, the cutter member and the rotatable blade are configured to form an opening into the sinus cavity. The fluid passage extends through the cutter member from an inlet to an outlet. The outlet is positioned proximal to the helical blade such that the outlet is configured to fluidly communicate with the sinus cavity. The inlet is configured to receive at least one of a fluid and a vacuum in order to communicate the respective fluid or vacuum to the outlet for irrigating or suctioning the sinus cavity.

Apparatus to form opening in ethmoid bulla and irrigate ethmoid sinus cavity

Systems and methods are described for administering a solution to a tympanic membrane of an ear canal of a subject. In some embodiments, the system includes a fluid delivery channel with a proximal end, a distal end, and a lumen defined therebetween. The proximal end can include at least one of a valve and Luer connector for selectively establishing fluid communication between a solution source and the lumen of the fluid delivery channel. The distal end can include an atraumatic tip defining a plurality of spray holes for providing fluid communication between the lumen and the ear canal. The atraumatic tip can be capable of being inserted into the ear canal and positioned near the tympanic membrane with the plurality of spray holes substantially facing the tympanic membrane to fill the ear canal with the solution from a portion near the tympanic membrane out toward an outer ear portion.

A surgical blower for providing a directed stream to clear a surgical site, that can be used in multiple different use modes. In one use mode, the surgical blower is handheld by a user during operation. In another mode, a distal end portion of the blower is fixed to a foot of a stabilizer instrument and the handle of the blower is handheld. In another mode, a distal end portion of the blower is fixed to a foot of a stabilizer instrument and the handle of the blower is fixed to a stationary object such as a sternal retractor. In another mode, the distal end of the blower is free and the handle of the blower is fixed to a stationary object. An apparatus including a blower and a stabilizer is provided. Methods of using the blower as well as the apparatus are also provided.

Blower instrument, apparatus and methods of using

Methods and delivery devices for maximizing injectate dispersion in lesioned tissue using needle-based injection devices are herein disclosed. The delivery devices include injection devices with various needle arrays and/or modified needle tip configurations. The needle tip configurations can include linear, hooked or corkscrew tips and/or multiple circumferential openings.
