The invention relates to a non-heated humidification device comprising a wick; a chamber for holding water in contact with the wick; and a gas inlet to the chamber, wherein the chamber and wick are configured to humidify gas passing through or over the wick at ambient conditions. The device may be modular and attachable to a flow generator. The device may comprise dual gas circuits and a control system for controlling the gas flow through the gas circuits in order to control the humidity of the gas output.

Antibacterial coatings and methods of making the antibacterial coatings are described herein. A first branched polyethylenimine (BPEI) layer is formed and a first glyoxal layer is formed on a surface of the BPEI layer. The first BPEI layer and the first glyoxal layer are cured to form a crosslinked BPEI coating. The first BPEI layer can be modified with superhydrophobic moieties, superhydrophilic moieties, or negatively charged moieties to increase the antifouling characteristics of the coating. The first BPEI layer can be modified with contact-killing bactericidal moieties to increase the bactericidal characteristics of the coating.

An apparatus for pressurizing one or more airways of a user, including: a dental arch mold configured to receive a plurality of teeth, a port which may be at a front face of the dental arch mold, a first nasal pillow, a second nasal pillow, a multi-output air regulator, and a plurality of sensors. The multi-output air regulator and sensors allow the airway pressurization device to sense the pressures in as well as be in independent fluid communication with the port of the dental arch, the first nasal pillow, and the second nasal pillow, such that an equalization of pressures, or a determined pressure differential between each may be obtained.

A medical device comprising an implantable subcutaneous access port having a septum penetrable by a needle; the septum having a cavity located between an outer wall and an inner wall, the cavity containing a flowable media comprising a plurality of displaceable particles arranged to move in response to the needle being inserted through the outer wall and into the cavity and reposition around the needle.

A bougie is disclosed with a body, and a first depth indicator and a second depth indicator on the body. The body has a first end, a second end, and at least one surface extending between the first and second ends. The first depth indicator is spaced a first distance from the first end and indicates a first predetermined depth range such that the first end is positioned a first predetermined insertion range past the mouth of the patient when the body is positioned into the mouth of the patient. The second depth indicator is spaced a second distance from the second end and indicates a second predetermined depth range such that the second end is positioned a second predetermined insertion range past the mouth when the body is positioned into the mouth of the patient.

Various embodiments disclosed relate to drug-coated balloon catheters for treating strictures in body lumens and methods of using the same. A drug-coated balloon catheter for delivering a therapeutic agent to a target site of a body lumen stricture includes an elongated balloon having a main diameter. The balloon catheter includes a coating layer overlying an exterior surface of the balloon. The coating layer includes one or more water-soluble additives and an initial drug load of a therapeutic agent.

A coated urinary catheter or urinary stent device includes a urinary catheter or stent which, in a deployed position, includes or defines a protective surface area and a protected surface area and a coating upon at least a portion of the protective surface area. The coating includes a lubricant and an antimicrobial and/or pH buffering material. The device is configured such that, upon application of negative pressure to the catheter or stent, tissue of a urinary tract of a patient conforms or collapses onto the protective surface area and is thereby prevented or inhibited from occluding one or more protected drainage holes, ports or perforations of the catheter or stent.

The disclosure provides a method for preventing infection and microbial ingress in medical device connections between tubing sets and medical devices. The tubing set includes a male connector with a distal tip and a recess at the distal tip configured to trap bacterial, and deliver and confine antimicrobial into solution within a cavity formed by the recess. The surface of the recess includes an antimicrobial composition. In certain implementations a male luer comprises a tapered sealing member further comprising a recess containing chlorhexidine acetate.

The present disclosure is directed to a device for delivering an antimicrobial composition into an infusion device. The disclosure provides a method for preventing infection and microbial ingress in medical device connections. The device includes a male connector with a distal tip and a recess at the distal tip. The surface of the recess includes an antimicrobial composition. In certain implementations a male luer comprises a tapered sealing member further comprising a recess containing chlorhexidine acetate.

In some examples, a catheter assembly includes a catheter including an elongated catheter body defining a lumen, a first cuff and a second cuff. The first cuff includes a first cuff body comprising a material configured to promote epidermal tissue growth around or within the first cuff and an adhesive configured to adhere the first cuff body to an outer surface of the elongated catheter body at a first cuff position selectable by a user. The second cuff includes a second cuff body comprising the material configured to promote epidermal tissue growth around or within the second cuff body and an adhesive configured to adhere the second cuff body to the outer surface of the elongated catheter body at a second cuff position selectable by the user. A distance between the first and second cuff positions is customizable by the user based on a patient.
