An antimicrobial light dressing device, system and method for a percutaneous treatment that bathes a treatment region around the percutaneous insertion with an antibacterial illumination source for preventing pathogens around the insertion from entering via the dermal puncture created by the insertion. The antimicrobial light dressing device combines a circumferential body centered around the insertion, and an arrangement of LEDs around the body that focus the light around the insertion and onto a therapeutic region of the insertion. An opening in the circumferential body has an articulated protrusion for offsetting a medicinal vessel such as an IV tube off the skin surface to avoid blocking light to an area under the vessel.

Systems and methods of disinfection of catheter connections are provided. A transfer catheter connector can include a UV-transparent window at its distal end and a sealing plunger proximal to the UV-transparent window. A solution set connector can be inserted inside a portion of the transfer catheter connector to connect a solution set and transfer catheter. The solution set connector comprises a lumen covered by a leading membrane surface; a sealing surface configured to sealingly engage the window surface, and a piercing member configured to pierce the membrane surface. The sealing plunger, membrane surface, and window define a disinfection zone. The connectors can be connected in a disinfection position configuration in which flow is not permitted between the catheters and the connectors are irradiated with UV light. After disinfection, the connectors are advanced to a flow position in which the piercing member pierces the membrane surface, enabling flow between the catheters.

Disclosed herein is a blue light phototherapy system and methods of using the system to prevent and treat driveline bacterial infections, and particularly ventricular assist device driveline bacterial infections (Right Ventricular Assist Devices (RVAD) and Left Ventricular Assist Devices (LVAD)). The blue light phototherapy systems provide for both repeated and/or periodic antimicrobial treatment of soft tissue surrounding a driveline exit site on an individual. In many embodiments, the system includes one or more arrays of light emitting diodes (LED) of predominantly blue wavelengths in combination with a single or multi-piece biocompatible structure that captures the arrays and provides for a fixed distance from the arrays to the exit site tissue surface.

A driveline for an implantable blood pump including a percutaneous outer tube configured to connect with the blood pump when the blood pump is implanted within a body of a patient and an external controller outside of the body of the patient and at least one ultra-violet light emitter coupled to the outer tube.

Devices, methods, and systems for a luer connector treatment device are described herein. The luer connector treatment device may include one or multiple sources of UV radiation configured to emit UV radiation capable of sterilizing the contents of a treatment chamber while a first medical device (e.g., catheter) is connected to a secondary medical device, and while the first medical device is separate from a secondary medical device. Sources of UV radiation may be located along both a cap and body of the luer connector treatment device.

This invention is for a catheter apparatus that greatly reduces microbial infections resulting from catheterization of dialysis, semi-mobile, or hospitalized patients. The apparatus applies light in the ultraviolet and near ultraviolet band to multiple catheter lumens for both detection and inactivation of biofilm microorganisms. It uses real-time automated techniques for the selection of wavelength, power level and exposure time regimes that are used for irradiating the biofilm in vivo. Artificial intelligence is incorporated to adjust the UV irradiation regimes to maximize the microorganism inactivation efficacy while minimizing the destruction of keratinocytes. The biofilm inactivation efficacy of this infection resistant catheter apparatus is at least 99%. The apparatus allows for minimal deviation from conventional catheter insertion procedures and can remain in vivo for long periods of time without the risk of microorganism contamination.

Methods and apparatus for cleaning a central venous catheter port are disclosed. An apparatus includes a body, a coupling configured to connect the body to the hub, a cleaning cap coupled to the body, and an actuator disposed within the body for rotating and translating the cap relative to the hub. The cleaning cap includes a cap body defining a cavity and a cleaning member disposed within the cavity, the cleaning member having threads that engage with the threads on the hub.

A cap configured to disinfect a medical device or portion thereof, the cap comprising a power source that provides electric power, an electromagnetic radiation source that uses the electric power received from the power source to emit photons for disinfection and a switch that is configured to be operated by user action, wherein upon activation of the switch, the electric power from the power source is applied to the electromagnetic radiation source to radiate photons onto the medical device or portion thereof.

A gas delivery system (50) for delivering a flow of breathing gas to a patient (54) includes a blower assembly (100) structured to generate the flow of breathing gas. The blower assembly includes a gas flow path including an inlet manifold, an assembly (130) structured to adjust a pressure and/or flow rate of the flow of breathing gas, and an outlet manifold structured to be coupled to a patient circuit. The gas delivery system additionally includes a light system structured to generate sanitizing light and deliver the sanitizing light to one or more internal surfaces of at least one of the inlet manifold, the assembly and the outlet manifold for sanitizing the one or more internal surfaces.

A fluid delivery system includes a first container configured for storing a first fluid therein and a second container configured for storing a second fluid therein, wherein the second fluid is different from the first fluid. The fluid delivery system further includes at least one pump configured for delivering under pressure one or both of the first and second fluids. At least one valve is provided for selectively delivering one or both of the first and second fluids to the pump. The first and second containers, the pump, and the valve are contained within a cartridge that is removably insertable into a cartridge carrier of the fluid delivery system.
