A system for delivering a fluid to a Eustachian tube (ET) of a patient includes a guide member and a tubular member. The guide member includes a shaft having a proximal portion, a distal portion, and a bend at the distal portion. The bend is configured to provide access to an opening in the ET. The system further includes a tubular member comprising a proximal end, a distal end, and a lumen extending therebetween. The tubular member is sized to fit within the ET. One or both of the tubular member and the guide member comprises a first stop member configured to engage the other of the tubular member or the guide member. The first stop member is configured to restrict a distal advancement of the tubular member relative to the guide member.

The spray application device with angled tip may comprise an applicator and an activator, where the applicator has a nozzle for delivery of a sprayable material. The spray application device may store a medication and may dispense the medication as an aerosol mist. The medication applicator may be adapted to dispense the medication through a nostril of a user directed at the posterior nasal cavity. The spray application device may be operable to release the medication in multiple doses of predetermined volume. The spray application device may be adapted for the user to self-administer the medication while positioned in any preferred physical position. A nozzle with a compliant nozzle shroud, an angled tip, and anatomically optimized nozzle geometry may direct the medication to a precise location within the posterior nasal cavity of a user.

To reduce the suffering of the patient and enable easier removal of excess fluid such as pleural effusion fluid from the chest space, the disclosure provides a catheter for chest drainage intended for removal of excess fluid from a chest space of a living body and to be placed in the living body in such a manner as to extend from an inside of the chest space to an outside of the living body. The catheter includes a passage member formed of a flexible sheet and having a passage through which the excess fluid is to be drained, and an indwelling member formed of an elastic body and provided at a proximal end of the passage member. The indwelling member has an inlet that allows the excess fluid to flow through. The indwelling member includes a retaining portion spreading in a flange shape and being retainable at a chest wall.

A system including tubing and a filter configured to be fluidly coupled to a vacuum source and to a heater/cooler unit by the tubing. The filter includes a filter container having negative air pressure in the filter container provided by the vacuum source to pull aerosol from the heater/cooler unit into the filter container and eliminate and/or reduce the aerosol emitted from the heater/cooler unit.

Systems, instruments, and methods for minimally invasive procedures including one or more of fractional resection, fractional lipectomy, fractional skin grafting, fractional scar revision, and/or fractional tattoo removal are described. Embodiments include instrumentation comprising a scalpet assembly coupled to a carrier, and the scalpet assembly includes a scalpet array. The scalpet array includes one or more scalpets configured for fractional resection, fractional lipectomy, fractional skin grafting, fractional scar revision, and/or fractional tattoo removal. The system includes a vacuum component coupled to the scalpet assembly and configured to evacuate tissue from the a site. The carrier is configured to control application of a rotational force and/or a vacuum force to the scalpet assembly.
