摘要:
An intra-bronchial device provides a medicant intra-bronchially. The medicant may be used for controlling biological interaction of an intra-bronchial obstruction device with the patient, to treat a disease or condition of the lungs such as pneumonia or lung cancer, or to treat a systemic disease or condition. The medicant is provided by associating a medicant with the intra-bronchial device, either before, at the time of placement, or after placement. The medicant may overlie at least a portion of the intra-bronchial device, be absorbed into at least a portion of the intra-bronchial device, or be carried in a chamber. The intra-bronchial device may further include an absorptive member, and the medicant is absorbed by the absorptive member.

The present invention includes an intra-bronchial device, system, and method for providing a therapeutic agent to a patient. A device includes a flow control member for placement in an air passageway communicating with a lung portion, and when deployed in the air passageway inhibits a therapeutic agent distal of the control member from moving proximal of the control member, and includes the therapeutic agent associated with the flow control member. The control member may inhibit movement of the therapeutic agent by limiting airflow, and may include a one-way valve limiting exhalation of air from the lung portion. The control member may include a flexible membrane impervious to air flow, or a separator arranged to inhibit the movement of the therapeutic agent. The control member may include at least one anchor, and the anchor may be releasable from the air passageway for removal of the intra-bronchial device.

A system and method for performing a bronchoscopy. The system may include a bronchoscope, a multi-fluid conduit apparatus, and a switching apparatus. The bronchoscope may include an insertion tube having a distal end, a control section, and a working channel. The multi-fluid conduit apparatus may include a first conduit section operably coupled to a vacuum source, a second conduit section operably coupled to an oxygen source, and a third conduit section operably coupled to the working channel, each of the first and second conduit sections being fluidly coupled to the third conduit section. The switching apparatus may include a valve apparatus operably coupled to each of the first and second conduit sections and an actuator apparatus operably coupled to the valve apparatus. The actuator apparatus may alter the valve apparatus between: (1) a suction supply state; and (2) an oxygen supply state.

A device for introducing a material into a body cavity is shown. The device includes a catheter with a distal tip. A first lumen extends through the catheter. The catheter is configured to form a mist from liquid passed through the first lumen, for example including a misting nozzle in fluid communication with the first lumen and configured to provide a mist from a flow of liquid through the first lumen. An inflatable balloon may be included on the catheter to allow the user to isolate the portion of the body in which the material is introduced. Additional described features can provide for controlled deflection of a distal region of the catheter, guidewire or guide loop tool lumens, first and second misting nozzles on the catheter, and delivery apparatuses including the catheter devices coupled or that can be coupled to endoscopes such as bronchoscopes. Methods of use of the catheter devices and delivery apparatuses are also described.

Systems, devices, and methods for maintaining patency in a bronchus of a patient are presented. A catheter is positioned within the bronchus. A target region of one or more of a bronchial wall, submucosa, media, and adventitia is punctured with an injection needle disposed on a distal end of the catheter. Such puncturing is achieved by expanding a balloon disposed on the distal end of the catheter. The balloon may be comprised of at least two materials of different elastic modulus, which allows for a flexible but relatively non-distensible, unfolding component of the balloon as well as an elastomeric, inflatable component of the balloon. Through the injection needle, an amount of one or more crosslinking agents is delivered to the target region. The delivered amount is effective to provide structural support for the bronchial wall, substituting for the bronchial cartilage thereby treating bronchomalacia.

Disclosed are apparatus and methods for producing and delivering vapour medicament. An exemplary apparatus disclosed comprises: a gas inlet for receiving a gas from a source of pressurized gas; a chamber for receiving a liquid medicament therein, the chamber being in communication with the gas inlet for permitting entrance and expansion of the gas in the chamber in the presence of the liquid medicament to produce the vapour medicament; and a vapour outlet in communication with the chamber for delivering the vapour medicament.

Provided herein are medicament delivery systems for selectively providing radial, distal, or a combination radial and distal delivery spray patterns of a medicament, and a method of their use to treat a patient's airway. Generally, a medicament delivery system comprises an elongate shaft, a medicament source, and a means for controlling the delivery spray pattern of the elongate shaft. In use, the medicament delivery system is inserted into a patient's airway during a laryngoscopy procedure to deliver a topical anesthetic to the airway. The medicament delivery device can be used with both direct and indirect view laryngoscopy procedures.
摘要:
An apparatus comprises a balloon catheter, an inflatable balloon, and a force sensor. The balloon catheter is operable to communicate fluid to the balloon. The balloon is disposed on the distal end of the balloon catheter. The balloon is positionable within an airway or other anatomical passageway of a patient. The force sensor is positioned along the balloon catheter or in the balloon and is able to detect a physical change within the balloon catheter or balloon. A control logic may trigger a response based on readings by the force measuring device. For instance, the control logic may trigger an alert when a force related parameter exceeds a threshold; or when a rate of change in the parameter exceeds a threshold. In addition or in the alternative, the control logic may trigger a feature that is operable to reduce fluid pressure in the balloon in response to such conditions.
摘要:
The volume of a hyperinflated lung compartment is reduced by sealing a distal end of the catheter in an airway feeding the lung compartment. Air passes out of the lung compartment through a passage in the catheter while the patient exhales. A one-way flow element associated with the catheter prevents air from re-entering the lung compartment as the patient inhales. Over time, the pressure of regions surrounding the lung compartment cause it to collapse as the volume of air diminishes. Residual volume reduction effectively results in functional lung volume expansion. Optionally, the lung compartment may be sealed in order to permanently prevent air from re-entering the lung compartment.
