Devices, methods, and systems are provided for occluding a collateral flow channel between a target lung compartment and an adjacent lung compartment. A video-assisted thoracoscopic device is inserted into a thoracic cavity of a patient and positioned at a fissure between a target lung compartment and an adjacent lung compartment. A collateral flow channel between the target lung compartment and the adjacent lung compartment is then identified using the video-assisted thoracoscopic device and an agent is injected into the collateral flow channel, thereby reducing the collateral flow channel.

Methods, devices, systems of resuscitating a patient including accessing an arterial vessel positioning a catheter into the arterial vessel advancing the catheter through the arterial vessel to position it below a vessel supplying blood to a heart and a brain expanding an expandable portion of the catheter to prevent blood from flowing past the expanded portion and infusing a substance retrograde into the artery within the arterial section between the heart and the expanded portion of the catheter.

Disclosed herein are apparatus embodiments and methods for using same that facilitate occlusion of a lumen in a subject. In a particular example, the apparatus is configured for occluding a portion of the lower GI tract (e.g. colon). Further, the apparatus is configured for placement in the lumen and insufflation to secure within the lumen such that the apparatus remains in place without the need for uncomfortable conduits or tools extending out of the patient. In a particular method embodiment, the apparatus is useful for occluding a lumen following a surgical procedure such as an anastomosis.

A method includes inserting a first dilation catheter into a first nostril of a patient. A first dilator of the first dilation catheter is positioned between the nasal septum of the patient and the turbinate of the patient. The first dilator is expanded, thereby remodeling one or more of the nasal septum, the turbinate, or mucosal tissue of the patient. The first dilation catheter is removed from the nostril of the patient. A second dilation catheter may be inserted into a second nostril of the patient. A dilator of the second dilation catheter may provide an opposing force on the nasal septum to prevent over-medialization of the nasal septum.

The disclosure includes a vein ablation system, comprising a catheter having an elongated body. In some embodiments, the vein ablation system comprises an ablation device at a distal portion of the elongated body. According to some embodiments, the vein ablation system comprises a control device at a proximal portion of the elongated body. The control device may comprise an input mechanism configured to simultaneously control at least two of a longitudinal translation of the ablation device through a target vessel, a rotation of the ablation device about a central longitudinal axis, and an infusion of a chemical agent into the target vessel.

A device for perfusing a coronary sinus of a subject's heart which may include: a double-lumen catheter including: a first lumen having: a proximal opening, and a distal opening configured to be positioned in a coronary sinus of a subject's heart; and a second lumen parallel to the first lumen, the second lumen having: a proximal opening, and a distal opening being offset from the distal opening of the first lumen towards the proximal opening of the second lumen in a longitudinal direction, the distal opening of the second lumen being configured to be positioned in a right atrium of the subject's heart; and an oxygenator connected to the proximal openings of the first lumen and the second lumen, the oxygenator is configured to oxygenate deoxygenated blood.

Devices and methods for increasing a patient's pulmonary arterial compliance are disclosed. The devices include catheters designed to create a connection between a patient's venous anatomy and the patient's pulmonary artery. With the arteriovenous connection various devices can be implanted in order to increase the volumetric compliance of the pulmonary artery. The devices include collapsible and expandable mechanisms which allow the effective pulmonary arterial volume to expand during systole and contract during diastole. The devices may include a balloon or balloon-like implants which cyclically shuttle a working fluid from the pulmonary artery to the vein and back. The devices may be adjustable to provide desired hemodynamic benefits. Methods are disclosed for making and using the inventive devices.

A coaxial stabilizing and sealing catheter provides increased support to a guide catheter that is seated in an ostium of a branch artery by extending through and out of a distal end of the guide catheter and anchoring in position within the branch artery that is being treated. The stabilizing and sealing catheter includes, as part of a relatively flexible distal section, a balloon that locks a distal end of the stabilizing and sealing catheter in place to provide support to therapeutic devices that are introduced and further seals the branch artery to prevent blood from entering the branch artery. A sealing cuff at a proximal end of the stabilizing and sealing catheter provides a seal between an exterior of the stabilizing and sealing catheter and an interior of the guide catheter. In addition, a fixing mechanism is utilized to lock the guide catheter in place to exchange therapeutic devices.
