Described are methods for providing a pulsed dose of a gaseous drug over a portion of total inspiratory time, where the dose of the gaseous drug is delivered at a concentration of nL of gaseous drug per mL tidal volume.

Devices and methods for delivering oxygen and other therapeutic gases to a target, such as a tissue, a tissue-engineered construct, and a wound, in a controlled and sustained manner are disclosed.

The present invention provides for systems and methods for inhaled CO therapy to prevent, attenuate, or delay processes that accelerate the loss of organ or tissue function, thereby increasing the lifespan of transplanted organs or tissues, or slowing the decline of native organs or tissues, or delaying the need for replacement of diseased native organs with organ transplants. Such biological processes that are prevented, attenuated, or delayed include chronic persistent inflammation, fibrosis, scarring, as well as immunologic or autoimmune attack.

Described herein are introducer devices and methods for using an introducer device to facilitate passing an endoluminal instrument to a target region of a body cavity. An introducer device may include a tubular member having an inner wall that defines a channel configured to receive the endoluminal instrument and a plurality of projections disposed in the channel at perimetrically spaced apart locations around the inner wall, where the projections extend inward and are configured to offset the endoluminal instrument from the inner wall, thereby creating a space between the endoluminal instrument and the inner wall. A method for using an introducer device may include passing the endoluminal instrument to a first instrument insertion depth within the introducer device, advancing the introducer device in the body cavity, and advancing the endoluminal instrument to a second instrument insertion depth within the introducer device.

A valve assembly comprising a housing and a valve, the valve being disposed within the housing, a first indexed member integral to the housing, the first indexed member adapted to be complementary to a second indexed member, and a radio frequency identification device adapted to communicate with a radio frequency receiver, the valve being configured to align with a canister, seal the canister and open in a single movement. A drug containment device having said valve assembly is also disclosed.

A method and apparatus that provides a continuous source of medical grade air. A substantially tubular housing includes a first end, an aperture extending through the housing, and a second end, opposite the first end. A valve extends from the first end of the housing for dispensing medical grade air to a patient.

A load control system may control an electrical load in a space of a building based on one or more parameters regarding the physical condition of an occupant. The parameters may be gathered by one or more sensing devices. The sensing devices may be included in a mobile device. A system controller may receive the parameters and may automatically control the electrical loads in response to the parameters. The system controller may control the electrical load to attempt to adjust the physical condition of the occupant in response to the sensed parameters. The system controller may control the electrical load to provide an alert, an alarm, and/or a warning in response to the sensed parameters.

A gas-evolving composition delivery system is disclosed, which comprises a pressurized container having a dispenser, and a liquid gas-evolving composition, such as an acidified nitrite solution, within the pressurized container, wherein the pressurized container has an internal pressure sufficient to minimize gas production from the gas-evolving composition while within the container. Also disclosed is a method of stabilizing an acidified nitrite solution comprising loading the solution into a container and sealing the container to be airtight.
