A therapeutic gas is administered to a patient. A sample gas is drawn from the therapeutic gas supply, and passed through a water-permeable tubular membrane. Concurrently, a section of the water permeable tubular membrane is maintained as a ventilated water permeable tubular membrane, by exposing outer surfaces of the ventilated water permeable tubular membrane to an ambient air flow. The ambient air flow may in some examples be moved over the tubular membrane via forced air such as for example via a fan associated with a housing surrounding the tubular membrane.

A positioning and stabilising structure for a patient interface for delivery of a supply of pressurized air or breathable gas to a patient's airways may include a first fabric layer; a second fabric layer; a central fabric layer between the first fabric layer and the second fabric layer. The central fabric layer, the first fabric and the second fabric may be warp/weft knitted together.

A device includes a basal portion and a plurality of blade portions disposed on the basal portion. The blade portion has a thin shape, and a distal end portion of the blade portion has a convex shape.

An apparatus for transdermal injection includes a sleeve including a proximal end, a distal end, and an inner wall surface extending along the sleeve from a first opening at the proximal end to a second opening at the distal end. The inner wall surface forms a channel in the sleeve, the channel having a first portion with a substantially frustoconical shape. The channel of the sleeve is configured to receive a substantially frustconically shaped injection cartridge, to substantially uniformly support the injection cartridge during a transdermal injection operation, and to prevent movement of the injection cartridge out of the distal end of the sleeve.

A method for the fail-safe termination of in vivo drug delivery from an implantable drug delivery system, the method comprising: providing an implantable drug delivery system comprising: a housing having a reservoir for containing a drug, and a port for dispensing the drug to a patient; and an emergency deactivation unit disposed between the reservoir and the port, the emergency deactivation unit comprising a composite structure comprising a biocompatible ferromagnetic mesh open to fluid flow and a hydrophobic meltable material, the hydrophobic meltable material comprising at least one hole therein for enabling a fluid to pass through the hydrophobic meltable material; implanting the implantable drug delivery system within a patient; enabling the drug to flow from the reservoir, through the at least one hole in the hydrophobic meltable material and out the port; and when drug flow is to be terminated, applying a magnetic field to the composite structure, such that a current is induced in the ferromagnetic mesh which heats the ferromagnetic mesh and melts the hydrophobic meltable material, thereby closing the at least one hole in the hydrophobic meltable material and blocking drug delivery to the patient.

Described herein are systems and methods for attracting and trapping cancer cells at a specific site where focal radiation and/or surgical resection and/or chemotherapeutics can eliminate them.

Embodiments presented provide for a medical apparatus that allows for administration of a fluid, such as oxygen, to a patient, and to allow a medical professional to quickly and precisely administer such oxygen and/or a gaseous sedative with little waste.

An air delivery conduit includes first and second conduit portions that cooperate to form the conduit, each conduit portion including an inner layer of a film laminate that forms an interior surface of the conduit and an outer layer of a textile that forms an exterior surface of the conduit.

A medical device according to the disclosure includes: two members that are made of materials having different flexural moduli and are connected to each other, in which a soft member made of a material having a low flexural modulus of the two members includes a cylindrical portion, a hard member made of a material having a high flexural modulus of the two members includes a cylindrical support portion that supports the cylindrical portion, and the cylindrical support portion includes an inner surface support portion that supports an inner surface of the cylindrical portion, and an outer surface support portion that supports an outer surface of the cylindrical portion.

Formulations containing pharmaceutical active agent, propellant, and water at least partially adsorbed on or absorbed within one or more nylon pellets or nylon components of, for example, an inhaler such as a metered dose inhaler. Canisters, typically sealed canisters, containing such formulations. Inhalers, such as metered dose inhalers, containing such canisters. Methods of making and using the same.
