Methods and systems one or more for performing intra-luminal ultraviolet therapy for treating and/or ameliorating a gastrointestinal tract inflammation and/or infection are provided. In one example, a light delivery catheter may include a light emitting portion and non-illuminating portion, wherein the light emitting portion may include one or more UV transparent balloons. In some examples, the UV light source is configured to emit narrow-band light having wavelengths in a range between 335 nm and 349 nm.

Internal ultraviolet therapy

Described herein are methods of detecting levels hydrogen sulfide (HS) to diagnose HS positive disease or conditions. Examples of HS positive diseases and conditions include small intestinal bacterial overgrowth, diarrhea, fatigue, bowel urgency and abdominal pain. The HS level can guide treatments for subjects who have high levels of HS.

Measurement of hydrogen sulfide during breath testing

The disclosed technology relates to a system for delivering UV-A/B light with a catheter to treat infectious or inflammatory disorders in a patient. While UV light in the UV-C range has traditionally been used to treat skin disorders and for focused ablation of plaques in the arteries and other targeted internal uses, it has not been developed for broader infection, inflammation or neoplasia treatment inside the human body. Here, the inventor(s) developed a system for emission of therapeutic doses of UV light via a catheter, capsule, endoscope, tube or port that can be used to manage internal infections and inflammatory conditions inside a patient.

Systems and methods have been developed for implementation of a breath testing system for convenient sampling of intestinal gases exhaled from a patient's breath. This may include a system with a manifold that includes thermal regulation components, for instance thermistors and resistive heating elements, which maintain the temperature of the gases above the body temperature of the patient. In some examples, the system will determine an indication of whether a patient has SIBO by adjusting a change in exhaled hydrogen concentration by a methane level exhaled by a patient.

Breath gas analysis

A UV light delivery device for performing intra-corporeal ultraviolet therapy is provided. The device includes an elongated body separated by a proximal end and a distal end. The device also includes a UV light source configured to be received at the receiving space. In some examples, the UV light source is configured to emit light with wavelengths with significant intensity between 320 nm and 410 nm and is utilized in conjunction with an endotracheal tube or a nasopharyngeal airway.

Systems and methods have been developed for implementation of a portable SIBO testing system for convenient sampling of intestinal gases exhaled from a patient's breath. These devices may be in the form of a hand held meter that would integrate with a smartphone or other device with an application that can record data relating to food consumed by a user. Various technologies may be utilized to measure the levels of gases exhaled by a user, which may include (1) sorbent based technology and (2) membrane based technology. In some examples, the system will determine an indication of whether a patient has SIBO by adjusting a change in exhaled hydrogen concentration by a methane level exhaled by a patient.
