A stent delivery method includes: forming through-holes in an alimentary canal wall and a cyst wall so as to communicate with each other; passing a stent through the through-holes and placing a first expandable part in the alimentary canal and a second expandable part in the cyst; allowing the first expandable part to expand to an expanded state in the alimentary canal; and, after the expansion of the first expandable part, allowing the second expandable part to expand in the cyst while the alimentary canal wall is pressed by the first expandable part in the expanded state.

The present invention provides a catheter and gauze band that includes a catheter and gauze retaining sections along the outer and inner surface of the band with a specially adapted snap in device along the band to receive and retain a catheter tube. This present invention also includes methods of use.

Disclosed is a localized method for treatment of cancer including the steps of providing a drug delivery catheter; navigating the catheter to the bile duct; and delivering a therapeutic agent into the bile duct. According to one aspect of the method, the drug delivery catheter is a multi-occlusion balloon catheter. The multi-occlusion balloon catheter may include at least two balloons. The multi-occlusion balloon catheter may optionally include a pressure transducer between the balloons to optimize delivery technique.

This disclosure relates to a portable oxygen concentrator system. The system includes a case containing a portable oxygen concentrator, a mask, and a button. The case is configured to be worn on a user's back. The mask is configured to deliver oxygen from the portable oxygen concentrator to the user. The button, when activated, is configured to cause the portable oxygen concentrator to deliver an increased flow of oxygen to the user for a period of time.

Aspects of the technology described herein relate to delivery of pressure based on ultrasound data. Certain aspects relate to receiving ultrasound data collected from a subject by a wearable ultrasound device, determining that the ultrasound data indicates apnea (e.g., absence of lung sliding or movement of internal abdominal organs), and based on determining that the first ultrasound data indicates apnea, increase pressure being delivered to the subject. To increase the pressure, a positive airway pressure device may increase the pressure it generates, an adapter may route power to the positive airway pressure device, or a valve may permit air to flow from the positive airway pressure device to the subject. Increasing pressure may be triggered by an activation signal transmitted by the wearable ultrasound device or a processing device. The wearable ultrasound device may be a patch configured to couple to the subject's skin.

A device and method for inducing sleep, improving blood circulation, and correcting autonomous imbalances. The device includes a heat exchange member mounted on top of housing, the heat exchange member can receive a neck of a user and apply alternate hot and cold stimuli to the neck. The hot and cold stimuli improve blood circulation and correct the autonomous imbalances. The device includes a drive module and a heat sink to quickly switch from hot to cold.
