Abstract: Methods and systems for a catheter access port cleaning, disinfection or sterilization device are disclosed. The catheter access port cleaning, disinfection or sterilization device may comprise, a first housing having a power source and control circuit; a second housing shaped to mate with a catheter and having a first ultra-violet light source mounted therein, the first housing wired to the second housing to power the light source. When activated, the ultra-violet light source emits ultra-violet radiation that is transmitted from the second housing to the catheter attached to a patient. In this way, the device provides an efficient system for cleaning, disinfecting or sterilizing an access port in the second housing while reducing patient infections.

Abstract: Methods and systems are provided for sterilization. In one example, a device may include a body with a flexible tether and a receiving aperture having a central axis, the body forming an internal cavity, the cavity housing at least one circular battery with a central axis perpendicular to the central axis of the aperture; and a UV source positioned at an end of the receiving aperture. Various other additional features and alternative configurations are included.

Abstract: Methods and systems are provided for a stem cell organ device including an array of alternating stem cell channels and fluid channels. In one example, a method may include loading a stem cell channel with stem cells and flowing blood through a fluid channel in order to allow an exchange of molecules between the stem cells and the blood.

Abstract: Aspects of the present disclosure include embodiments of a positioning device and a method for using the same. The method may comprise applying pressure during an ultrasound examination. Embodiments of the disclosed positioning device include an arch configuration and an arm configuration to span across a gurney and over a patient on the gurney, the arch including a track that spans at least part of a length the arch, and an instrument attachment attached to the track of the arch, or an arm with multiple joints with an instrument attachment attached to the distal end of the arm, which serves to assist the motions of the user. The instrument attachment is configured to hold an instrument, such as an ultrasound transducer, and may extend the instrument toward the patient, such as to apply pressure to the patient during an ultrasound examination.
