A liquid injectable pharmaceutical drug product consisting of no less than 99 percent ethanol comprised of no less than 99 percent ethanol active pharmaceutical ingredient with a volume of at least 0.05 mL to be injected into a patient as a method of ablating/lysing cells.

In a method for diagnosing, validating and treating a patient having lesions in both arteries of left and right lower limbs. By determining that a harder lesion to be treated first, catheters and an operation time can be reduced is to be treated first on a priority basis based on diagnostic data, deciding that a softer lesion is to be treated next, then treating the lesions substantially continuously.

Described herein are devices, methods and kits for assessing and/or enhancing the accessibility of a subvalvular space of a heart, accessing the subvalvular space of the heart (e.g., to provide access for one or more other devices), and/or positioning one or more devices in the subvalvular space of the heart. The devices described herein may, for example, comprise catheters that may be used to manipulate one or more chordae tendineae, diagnostic catheters having different sizes and/or shapes (e.g., different curvatures), guide catheters having different sizes and/or shapes (e.g., different curvatures), and visualization catheters. In some variations, the devices, methods, and/or kits may be used to visualize a target site, such as a subannular groove of a heart valve. In certain variations, the devices, methods, and/or kits may be used to manipulate chordae tendineae to provide additional space in a ventricle of a heart (e.g., enhancing the accessibility of the ventricle).

Described here are devices, methods, and kits for the deployment of tissue anchors. In some variations, the devices may comprise a shaft defining a lumen for housing at least one anchor therein and a mechanism for deploying the anchor distally from the lumen. In certain variations, the devices may comprise one or more stop elements. For example, a device may comprise a stop element that limits the advancement of the device through an opening in a wall portion or at the distal end of another device.

Systems and methods are provided for removing air from a medical device, such as a stent-graft and/or its delivery device. In an exemplary embodiment, the stent-graft or its delivery system or both are exposed to perfluorocarbon, by immersing the stent-graft or flushing the delivery device to remove air from the stent-graft. Optionally, the stent-graft and/or delivery system may be flushed multiple times, e.g., with perfluorocarbon before or after flushing with carbon dioxide, saline, a bio-inert gas, and the like. Thereafter, the stent-graft may be introduced into a patient's body and deployed at a target location, such as the site of an abdominal aortic aneurysm.

Devices, systems and methods for controlling, regulating, altering, transforming or otherwise modulating the delivery of a substance to a delivery site. The devices, systems and methods optimize the delivery of the substance to an intended site, such as a vessel, vascular bed, organ and/or other corporeal structures, while reducing inadvertent introduction or reflux substance to other vessels, vascular beds, organs, and/or other structures, including systemic introduction.

Systems and methods for systems and methods for focal cooling of the brain and spinal cord are disclosed. Some embodiments may be directed to a neuroprotection system that includes a cerebrospinal fluid processing platform. Embodiments may provide rapid and selective spinal cord hypothermia and drainage. Embodiments may be tailored to selective spinal cord cooling, pressure monitoring and automated drainage. Embodiments may enable local hypothermic neuroprotection, limit the stress of systemic cooling, minimize secondary neuronal damage and achieve maximal neuroprotection while at the same time improving workflow as a result of automated drainage. Embodiments may include a multi-lumen catheter, a drainage collection reservoir bag, a pump to circulate coolant, sensor hardware and controllers to modulate the flow of a heat transfer fluid for cooling to modulate therapeutic hypothermia and re-warming. Certain embodiments may include extracorporeal cooling of cerebrospinal fluid (CSF). Certain embodiments may include circulating heat transfer fluid within a CSF-containing space near the brain or spinal cord using a catheter. Particular methods may be used to determine the length and amount of cooling.

Systems and methods for partial aortic occlusion are provided. The system may include a catheter having an expandable aortic blood flow regulation device disposed on the distal end of the catheter for placement within an aorta of a patient, and a catheter controller unit that causes the device to expand and contract to restrict blood flow through the aorta. The system also may include sensors for measuring blood pressure distal and proximal to the expandable device. The system further may include non-transitory computer readable media having instructions stored thereon, wherein the instructions, when executed by a processor coupled to the sensors, cause the processor to estimate aortic blood flow based on the measured blood pressures and corresponding waveforms, compare the estimated aortic blood flow with a target aortic blood flow range, generate an alert if the estimated aortic blood flow falls outside the target aortic blood flow range, and cause the catheter controller unit to adjust expansion and contraction of the expandable device to adjust an amount of blood flow through the aorta if the estimated aortic blood flow falls outside the target aortic blood flow range.

Systems and methods for Endovascular Perfusion Augmentation for Critical Care (EPACC) are provided. The system may include a catheter having an expandable aortic blood flow regulation device disposed on the distal end of the catheter for placement within an aorta of a patient. The system may also include a catheter controller unit that causes the expandable aortic blood flow regulation device to expand and contract to restrict blood flow through the aorta. The system may also include one or more sensors for measuring physiological information indicative of blood flow through the aorta, and a non-transitory computer readable media having instructions stored thereon, wherein the instructions, when executed by a processor coupled to the one or more sensors, cause the processor to compare the measured physiological information with a target physiological range associated with blood flow through the aorta such that the catheter controller unit automatically adjusts expansion and contraction of the expandable aortic blood flow regulation device to adjust an amount of blood flow through the aorta if the measured physiological information falls outside the target physiological range.
