Devices, systems and methods for treating bronchial constriction related to asthma, anaphylaxis or chronic obstructive pulmonary disease wherein the treatment includes stimulating selected nerve fibers responsible for smooth muscle dilation at a selected region within a patient's neck, thereby reducing the magnitude of constriction of bronchial smooth muscle.

A method for treating Chronic Obstructive Pulmonary Disease (COPD) or chronic bronchitis to alleviate the discomforts of breathing by using non-thermal electroporation energy to ablate diseased portions of the lung including the bronchus, airways and alveoli which, in effect, opens the restrictive diseased portions thereby maximizing the overall surface area thereof causing improved airflow and uninhibited breathing.

Medical devices, systems, and methods are provided for providing respiratory therapy by electrically stimulating the phrenic nerves and / or the thoracic diaphragm. In one embodiment, at least one electrode is deployed to a position within the patient's airway and placed in proximity to a phrenic nerve or to the diaphragm. The electrode may be attached to a controller housing including a pulse generator using one or more electrical lead or leads or may be in wireless communication with the pulse generator. The controller housing may be implanted at a position within the patient or the controller housing may reside external to the patient.

A nerve monitoring device, including a cannula, a sensor for monitoring a nerve, and an optional support element, can be inserted into an anatomic space. The cannula, sensor and / or support element can automatically conform to and match the geometry of the anatomic space, which can enhance desired contact between the sensor and anatomic features, such as muscles, nerves or tissue in the space in an atraumatic manner. The sensor, cannula and / or support element can include one or more strips or other elements that convert from a retracted mode to an expanded mode in which the strips or elements expand, enlarge or otherwise move to match the geometry of the space and place the sensors in precise monitoring proximity relative to the target muscles, nerves or tissues. An exemplary application of the device is in the field of laryngeal monitoring, however, the device is well suited for other applications.

A method for treating a pulmonary condition in a subject is provided. One step of the method includes providing an apparatus for positioning at a target site innervated by at least one nerve of the autonomic nervous system (ANS). The apparatus includes a fluid exchange catheter, an inflatable balloon coupled to the fluid exchange catheter, and an energy delivery mechanism including at least one energy delivery member for delivering electrical energy to the target site. Next, an expansion medium is delivered to the apparatus so that the inflatable balloon is sufficiently inflated to sandwich at least a portion of the at least one energy delivery member between the inflatable balloon and a luminal wall of the tracheo-bronchial tree at the target site. Electrical energy is then delivered to the at least one energy delivery member to effect a change in the ANS of the subject.

The present invention relates to apparatus and methods for electrically inducing, pharmacologically maintaining cardiac asystole. The present invention also provides cutaneous array electrodes (900) that may be used non-invasive to stimulate the vagus nerve.

The present invention provides systems, apparatus and methods for selectively applying electrical energy to body tissue. A device is provided having an enclosure within an outer wall formed from an electrically-permeable material to allow for electrical energy to pass from the interior of the enclosure through the outer wall. The device further includes an electrode positioned within the interior of the enclosure and a fluid passage coupled to the enclosure for delivery of an electrically conductive fluid into the interior of the enclosure such that the electrically conductive fluid couples the electrode with the electrically-permeable section of the outer wall. The conductive fluid allows for the passage of electrical energy from the electrode through the fluid and the outer wall of the enclosure for treatment of tissue on or in a patient. In this manner, the electrode does not directly contact the tissue of the patient, which reduces the potential for collateral tissue damage or necrosis and / or excessive electric fields in the tissue.

An airway implant device for maintaining and / or creating an opening in air passageways is disclosed. Methods of using the device are also disclosed. The airway implant device comprises a deformable element to control the opening of an air passageway. Preferably the deformable element is an electroactive polymer element. Energizing of the electroactive polymer element provides support for the walls of an air passageway, when the walls collapse, and thus, completely or partially opens the air passageway. Methods of treating airway disorders such as sleep apnea and snoring with the airway implant device are disclosed herein.

An electrode for laryngeal electromyography that is attachable to an insert device, endotracheal tune or other similar device that is also size adjustable by cutting to size. The attachable and size adjustable surface electrode of this invention consists of a flexible plate having an anterior and a posterior surface specifically for inserting in the human laryngopharynx adjacent to the cricothyroideus muscles (the vocal cords). An electrical conductive plate is mounted on the anterior surface to provide an electric contact with the cricothyroideus muscles. An insulated wire extends from the electrical conductive plate for monitoring or delivering electrical pulses to the cricothyroideus muscles. There are marked graduations parallel to a center line on the electrical conductive plate for cutting and sizing the flexible plate and electrical conductive plate to the size of the patient's laryngopharynx. There is an adhesive material on the posterior surface of the flexible plate for attachment of the attachable and size adjustable surface electrode for laryngeal electromyography to an endotracheal tube, insert device, postcricoid paddle or other such device.
