Implant devices for hypertension and methods of treatment are provided. Implant devices are configured for placement in a target region of an aortic arch of the patient, thereby engaging arterial walls in the target region sufficiently to stretch and / or tension arterial walls, thereby inducing the baroreflex response. Such implants can include one or more expandable structures configured to engage an elongated target region in the aortic arch. The target region can extend along a majority of the aortic arch including a cylindrical segment of aortic arch between the left common carotid artery and the left subclavian artery. An elongated target zone can further extend at least between the brachiocephalic artery takeoff and the left subclavian artery takeoff. Such embodiments can utilize one or more expandable structures with a non-circular cross-section that stretch and reshape the arterial walls to induce tension in the arterial walls, thereby generating a robust baroreflex response.

System, devices and methods for providing a blood-free operative region for aortic arch repair procedures. Various embodiments disclose occlusion of the descending aorta, the innominate artery, the left carotid artery and the left subclavian artery while also providing sufficient perfusion distal of the occluding balloons. Various embodiments disclose performing aortic arch repair procedures while the patient's body temperature is maintained an normothermia (about 36 degrees C. to about 37.5 degrees C.). Other embodiments disclose performing aortic arch repair procedures while the patient's body temperature is maintained at slight hypothermia (about 30 degrees C. to about 34 degrees C.).

The present application relates to the technical field of data processing, in particular to a pediatric transcarotid arterial and venous ECMO cannulation depth prediction method and system, comprising: selecting a data object; incision position positioning; according to the corresponding incision position, measuring the depth of the common carotid artery to the innominate artery into the aortic arch at the corresponding incision position as the ECMO arterial cannulation depth; according to the corresponding incision position, measuring the depth of the internal jugular vein to the inferior vena cava into the right atrium at the corresponding incision position as the ECMO venous cannulation depth; establishing a prediction formula; outputting the prediction result for reference; the present application summarizes the existing pediatric transcarotid arterial and venous ECMO cannulation experience, calculates and verifies the prediction formula of the transcarotid arterial and venous ECMO cannulation depth, so as to provide a reference to help doctors more accurately estimate the cannulation depth before cannulation, reduce complications caused by improper cannulation position; the prediction formula can be used as part of the standardized operation, improve the success rate and safety of ECMO cannulation.

The invention relates to the technical field of data processing, in particular to a child jugular arteriovenous ECMO intubation depth prediction method and system, and the method comprises the steps: selecting a data object; positioning a notch position; according to the corresponding incision position, measuring the blood vessel depth from the common carotid artery to the unknown artery to the aortic arch at the corresponding incision position as the ECMO arterial intubation depth; according to the corresponding incision position, measuring the depth from the internal jugular vein to the inferior vena cava entering the right atrium at the corresponding incision position as the ECMO vein intubation depth; establishing a prediction formula; outputting a prediction result for reference; according to the method, by summarizing the existing infant jugular artery and vein ECMO intubation experience, the prediction formula of the jugular artery and vein ECMO intubation depth is calculated and verified, so that reference can be provided to help a doctor to more accurately estimate the intubation depth before intubation, and complications caused by improper intubation position are reduced; the prediction formula can be used as a part of standardized operation, and the success rate and safety of ECMO intubation are improved.

The techniques of this disclosure generally relate to modular stent device and method of deploying the same. The method includes introducing a delivery system including the modular stent device via supra aortic access. The delivery system is advanced into the ascending aorta. Once positioned, the modular stent device is deployed from the delivery system such that an artery leg of the modular stent device engages the brachiocephalic artery and a bypass gate engages the aorta, wherein the artery leg partially collapses the bypass gate. The artery leg has a greater radial force than the bypass gate such that the artery leg remains un-collapsed and opened. Accordingly, blood flow through the artery leg and perfusion of the brachiocephalic artery and preservation of blood flow to cerebral territories including the brain is insured.
