Methods, devices, and systems are described for an acne extractor for treating superficial acne. The acne extractor includes a curved elongated handle having a distal end. A head is coupled to the distal end of the curved elongated handle. The head extends from curved elongated handle at an angle and has a loop with an inner diameter. The inner diameter is configured to encircle a skin irritation. The loop is configured to apply an inward pressure to the skin irritation in response to pressing the loop against skin surrounding the skin irritation using the curved elongated handle.

A refrigerant dispenser for tick removal can include a main body, an actuator structure, and a cage. A main body can include a proximal end, a distal end, and a cavity that extends from the proximate end to the distal end, with the proximate end having an intake opening in communication with the cavity and being configured to receive a refrigerant canister therein. An actuator structure can be connected to the distal end and can be in communication with the cavity. A cage can include an upper portion connected to the actuator structure and in communication with the cavity, and a lower portion terminating at an exhaust opening. The lower portion can be configured to at least partially surround a tick, and the exhaust opening can be in communication with the cavity.

A constraining structure for use with a balloon catheter can include multiple longitudinal struts and multiple, sinusoidal shaped radial rings. The constraining structure can expand to form a pattern of channels including substantially square windows. The constraining structure can modify, restrict, and control a shape and/or size of the balloon when inflated. Inflating the balloon catheter within the constraining structure can provide nonuniform pressure on a vessel wall adjacent the balloon.

Endoscopic tools or instruments having one or more side-deployable snare loop tools are provided. Loop wire tools connected by cables to proximal controlling handles are introduced though side openings in the tools which are located proximal to the distal end of the tools which may also include a soft, blunt tip designed to rest against a body cavity wall for stability. Side introduction of the wire loop tools into a human cavity allows for angulation and positioning favorable to perform endoscopic intervention, particularly when dealing with elongated foreign bodies or impacted food in the esophagus.

Viruses around the uterine orifice and in the vagina are reliably and safely removed with a simple configuration. A virus removal device includes a drive source that generates power, a contact part that comes into contact with an affected part around the uterine orifice or in the vagina, a power transmission part that transmits the power generated by the drive source to the contact part, and an operation part that operates a position of the contact part, in which the contact part is operated by the operation part while being driven by the drive source, thereby scraping tissue of the affected part. The contact part scrapes the tissue of the affected part in squamo-columnar junction, which is a common site of cervical cancer, thereby physically removing the virus contained in the tissue of the affected part to prevent and treat cervical cancer.

An apparatus for treating skin has a console with a user input device and a handpiece assembly. The handpiece assembly is configured to treat skin. A fluid line provides fluid communication between the console and the handpiece assembly. A manifold system is coupled to the console and controlled by the user input device. The manifold system is configured to hold releasably a plurality of fluid sources and deliver fluid from at least one of the plurality of fluid sources to the handpiece assembly.
