Described herein is a fingertip cleaning apparatus comprising a fingertip receiving portion including a conical wall defining a cavity having an open end configured to allow a fingertip of a user to be inserted into the cavity, the conical wall extending along and surrounding a cone axis, the conical wall forming a cone angle with the cone axis, a gripping portion comprising a flap that extends from the conical wall of the e fingertip receiving portion along a grip axis that forms a grip angle with the cone axis; and the grip angle being greater than the once angle.

System and method for modification of fluid environment of an ear. In one embodiment, the system includes an earpiece mountable within an ear canal. The earpiece includes a fluid delivery path for fluid to be delivered to the ear and a fluid removal path for fluid to be removed from the ear. The system also includes an electronics housing. The electronics housing may be directly mounted on the earpiece or positioned outside the ear. The system further includes an electrochemical gas generating device positioned within the electronics housing. In use, oxygen or the like is generated by the electrochemical gas generating device and is conveyed through the fluid delivery path of the earpiece, emerging from the earpiece distal end. The gas released from the earpiece causes fluid in the ear to be swept into the fluid removal path of the earpiece and eventually expelled to the outside of the ear.

An introducer apparatus includes an outer sleeve and an inner cannula received within the lumen of the outer sleeve. The outer sleeve has a profile such that at least a portion of the distal end of the outer sleeve tapers in the distal direction at an angle not exceeding about 2° relative to a longitudinal axis of the apparatus. The distal open end of the outer sleeve has a wall thickness not exceeding about 0.003 inch. The inner cannula includes a tapered distal end portion. The tapered distal portion of the inner cannula extends distal to the distal open end of the outer sleeve, such that a generally smooth diametrical transition is provided between the outer sleeve tapered portion and the open distal end of the inner cannula.

A myringotomy device includes a housing; an elongated tube extending from the housing; and a retractable cutting tool extendable through the elongated tube, the cutting tool comprising a blade. The cutting tool is configured such that when advanced, the blade of the cutting tool extends beyond a distal end of the elongated tube. The cutting tool is also configured such that when retracted, the blade is retracted into the elongated tube and a fluid conduit is created from the distal end of the elongated tube to the housing.

Methods and devices are adapted for implanting into the eye. An incision is formed in the cornea of the eye and a shunt is inserted through the incision into the anterior chamber of the eye. The shunt includes a fluid passageway. The shunt is passed along a pathway from the anterior chamber through the scleral spur of the eye into the suprachoroidal space and positioned in a first position such that a first portion of the fluid passageway communicates with the anterior chamber and a second portion of the fluid passageway communicates with the suprachoroidal space to provide a fluid passageway between the suprachoroidal space and the anterior chamber.

A ventilation device includes a hollow body having a main portion, at least one distal member coupled to a distal end of the main portion and at least one proximal member coupled to a proximal end of the main portion. The at least one distal member is formed of a shape memory material. The hollow body includes a deployed state for maintaining an opening in an anatomical structure and an undeployed state. The shape memory material forms the at least one distal member into a deployed position. The shape memory material is reversibly deformed from the deployed state into the undeployed state such that at least the distal member changes in shape to an undeployed position, while the main portion of the hollow body remains unchanged.

A kit is provided comprising a stent, an introducer and a bender. The stent is constructed for insertion into a Eustachian tube of a human. The stent includes a member having a preinsertion form that includes opposing exterior surfaces, means for immobilizing the stent within the Eustachian tube, and means for providing fluid communication between the opposing surfaces to effect pressure equilibration therebetween. The introducer includes a guide, an engager, and a sliding mechanism. A Eustachian tube method is also provided. The method involves using the above-described kit.

Foreign matters of variable size in the interior of one's auditory canal are removed infallibly.

An image capturing tube 220 adapted to be inserted into one's auditory canal to output an image of an interior of the auditory canal, a suction tube 230 provided along the image capturing tube 220 to suck a foreign matter in the interior of the auditory canal, and a main body unit 200 provided with the image capturing tube 220 and the suction tube 230 are included. The image capturing tube 220 includes a camera 240 adapted to capture the image of the interior of the auditory canal, and to a tip end of the suction tube 230, a dust collecting tube 232 is attached.
