Methods of delivering a vaporized agent to a subject are also provided. The methods include storing a liquid agent in a reservoir of a device and flowing the agent into a flow control chamber to change the agent to a gas. The methods also include mixing the agent in gas form with air and flowing the agent and air mixture out of the device to be delivered to a subject.

Embodiments of the present invention provide a device and a method for treating at least one of hypertension, pulmonary arteries, diabetes, obesity, heart failure, end-stage renal disease, digestive disease, nonalcoholic fatty liver disease, urological disease, cancers, tumors, pain, asthma or chronic obstructive pulmonary disease by delivering an effective amount of a formulation to a tissue. In embodiments of the present invention, the formulation may include at least one of a gas, a vapor, a liquid, a solution, an emulsion, or a suspensions of one or more ingredients. In embodiments of the present invention, amounts of the formulation and/or energy are effective to injure or damage tissue, nerves, and nerve endings in order to relieve disease symptoms.

A vented chest wound seal for a penetrating chest wound including a flexible sheet including a bottom surface, and an adhesive layer covering a portion of the bottom surface of the flexible sheet, the adhesive layer including an inner perimeter and an outer perimeter, the inner perimeter defining a chamber, wherein the chamber includes a vent channel extending radially outward from a central portion of the chamber, wherein the flexible sheet includes a vent hole aligned over the vent channel, and wherein the inner perimeter and the outer perimeter are separated by a minimum hydrogel width.

A wound care system for reduced pressure therapy comprising a covering device that can be fixed to the skin surrounding a wound and serving to produce a closed wound space containing the wound, a valve system, designed on the one hand to suck gases out of the wound space and on the other hand to counter the penetration of gases into the wound space, being assigned to the covering device after fixing the covering device to the skin surrounding the wound, the valve system being able to be coupled detachably to a suction device that can be operated to suck gases out of the wound space.

In accordance with one embodiment of the present disclosure, a surgical method may include making an incision in a patient. The method may also include opening the incision in order to create an open surgical site in the patient. The method may further include receiving a gas from a source. The method may further include humidifying and warming the gas received from the source. The method may further include successively reflecting the humidified and warmed gas off a plurality of non-porous surfaces within a non-porous gas delivery mechanism to create a flow. The method may further include delivering the flow of the humidified and warmed gas adjacent to or into the open surgical site.

Embodiments of the present invention provide a device and a method for treating at least one of hypertension, pulmonary arteries, diabetes, obesity, heart failure, end-stage renal disease, digestive disease, urological disease, cancers, tumors, pain, asthma or chronic obstructive pulmonary disease by delivering an effective amount of a formulation to a tissue. In embodiments of the present invention, the formulation may include at least one of a gas, a vapor, a liquid, a solution, an emulsion, or a suspensions of one or more ingredients. In embodiments of the present invention, amounts of the formulation and/or energy are effective to injure or damage tissue, nerves, and nerve endings in order to relieve disease symptoms.

An ion-exchange membrane electrolysis device includes an ion-exchange membrane electrolytic cell and an integrally formed integrated flow channel device. The ion-exchange membrane electrolytic cell generates a gas comprising hydrogen. The integrated flow channel device has a first setting structure, a water tank structure, a gas flow channel system and a water flow channel system. The water tank structure accommodates water. The first setting structure is configured for removably fixing the ion-exchange membrane electrolytic cell to the integrated flow channel device. The water flow channel system connects the water tank structure and the first setting structure for inputting the water in the water tank structure into the ion-exchange membrane electrolytic cell. The gas flow channel system is connected to the first setting structure for receiving and transporting the gas comprising hydrogen. Therefore, the present invention integrates functionally independent pathways, decreases pipeline connections, reduces volume of device, and improves safety of operation.

A seal anchor member defines a housing defining a longitudinal axis, the housing having leading and trailing ends, and including a plurality of lumens extending between the leading and trailing ends, each lumen being adapted for substantially sealed reception of an object therein and defining a longitudinal axis, wherein at least two of the lumens define longitudinal axes that are intersecting. The seal anchor member may be formed from a compressible material.

Embodiments of the present invention provide a device and a method for treating at least one of hypertension, pulmonary arteries, diabetes, obesity, heart failure, end-stage renal disease, digestive disease, urological disease, cancers, tumors, pain, asthma or chronic obstructive pulmonary disease by delivering an effective amount of a formulation to a tissue. In embodiments of the present invention, the formulation may include at least one of a gas, a vapor, a liquid, a solution, an emulsion, or a suspensions of one or more ingredients. In embodiments of the present invention, amounts of the formulation and/or energy are effective to injure or damage tissue, nerves, and nerve endings in order to relieve disease symptoms.

A filter cartridge for surgical gas delivery systems includes a filter housing configured to be seated in a filter cartridge interface of a surgical gas delivery system, with a plurality of flow paths defined through the filter housing including at least one evacuation/return flow path and at least one insufflation/sensing flow path. A humidity filter element is included in the evacuation/return flow path for removing humidity from an evacuation/return lumen of a tube set. The humidity filter element can include a sintered polymer material configured to provide tortuous flow paths therethrough to condense humidity out of a flow through the humidity filter element.
