A drug delivery port including a port housing having an inner sidewall defining a fill port cavity and a fill port washer in direct contact with a perimeter edge of the inner sidewall of the port housing such that an intersection between the washer and the perimeter edge define a plurality of filter channels having a cross-sectional flow area of about 0.001 mm.sup.2 to about 0.5 mm.sup.2 that lie within the fluid pathway of the delivery port. The delivery port also includes a port cover coupled and a pierceable septum compressed between the fill port washer and the port cover configured to allow a needle to pierce through the septum to deliver an injectable fluid to the fill port cavity.

A patient interface for use in delivering a flow of breathing gas to an airway of a patient. The patient interface includes a front portion and a rear portion coupled to the front portion. The front portion and the rear portion together define a cavity therebetween which is structured to receive the flow of breathing gas. The rear portion includes a support layer disposed directly adjacent the cavity, the support layer having a region having a plurality of first thru-holes structured to receive the flow of breathing gas from the cavity. The rear portion further includes a patient engaging layer structured to engage the patient at or about the airway of the patient, the patient engaging layer including at least a second thru-hole structured to receive the flow of breathing gas from the plurality of first thru-holes.

The present embodiments provide strain relief members for a medical device delivery system, methods of use thereof, and methods of manufacturing. In one embodiment a strain relief member may include a support having a first end with a first outer diameter, a second end having a second outer diameter, an inner surface facing a support lumen that extends axially through the support along a longitudinal axis, and an outer surface opposite to the inner surface. An embodiment may also include an overlay coupled to a portion of the outer surface of the support, where the overlay comprises a first material and the support comprises a second material, and the first material is more flexible than the second material. A liner may be disposed in a portion of the support lumen and a first connector disposed over a portion of the support.

An example device suitable for collecting and transporting urine away from the body of a person may include a fluid impermeable housing defining an internal volume. The device can include a porous material disposed within the internal volume. The fluid impermeable housing can define an opening in fluid communication with the internal volume. The porous material includes a contact surface and first and second sidewalls. The sidewalls can extend from the contact surface, for example, substantially orthogonal to the contact surface, or laterally and inwardly from the contact surface at an acute angle.

A flushable catheter assembly includes a catheter shaft having proximal and distal end portions. The catheter may include a funnel assembly associated with the distal end portion of the catheter shaft and/or an introducer cap assembly associated with the proximal end portion of the catheter shaft. A groove is defined along at least a portion of an outer perimeter of the funnel assembly or introducer cap assembly, with the groove being configured to receive at least a portion of the catheter shaft for wrapping the catheter shaft around the outer perimeter when disposing of the catheter. Instead of (or in addition to) a groove, one or more channels may pass through the funnel assembly to receive a portion of the catheter shaft for securing the catheter shaft to the funnel assembly for disposal. The catheter assembly and/or its individual components may be formed of a water disintegrable material.

An endotracheal tube apparatus to treat a patient comprising an endotracheal tube and a hub connection fitting; the endotracheal tube insertable into a trachea of the patient; the hub connection fitting connectable to the endotracheal tube; a ventilation passageway extending through the hub connection fitting and a ventilation lumen of the endotracheal tube; a plurality of ports joined with the hub connection fitting, the plurality of ports comprising at least a first port and a second port; a first passageway extending within the hub connection fitting, the first passageway in fluid communication with the first port; a second passageway extending within the hub connection fitting, the second passageway in fluid communication with the second port; a third passageway extending within the hub connection fitting and a secondary lumen of the endotracheal tube.

A package includes a tray having a plurality of openings and a plurality of barrel covers. Each of the plurality of barrel covers extend through one of the plurality of openings. A tub can receive the tray. A plurality of tamper evident devices can be attached to the plurality of barrel covers. Each tamper evident device includes a collar, a tamper evident cap, and a frangible connection between the collar and the tamper evident cap. A method of packaging a plurality of syringe bodies includes inserting the plurality of syringe bodies into a plurality of barrel covers positioned in a tray, and inserting the tray into a tub.

A device for biofilm removal from an endotracheal tube is disclosed. Such a device may include a hollow catheter having a tip, wherein said device is inserted down an endotracheal tube of an orally intubated patient. Said tip may include a cylindrical central portion and a fin configured to dislodge biofilm from the inner lumen of the endotracheal tube as the device is rotated, either manually or mechanically, inside the endotracheal tube. The fin may be configured as a helix and positioned to spiral around said cylindrical central portion of the tip thereby forming a channel, defined by the pitch of said helix, about the circumference of the cylindrical central portion. Biofilm dislodged from the inner surface of the endotracheal tube by the rotational motion of the fin may be retained within the channel until the tip is removed from the endotracheal tube. The device may further comprise a motor for mechanically rotating the catheter and tip. Finally, the device may be configured to interface with a mechanical ventilator such that airflow to an intubated patient is not impeded while said device is used to remove biofilm from the inner surface of the patient's endotracheal tube.
