Improved systems including rBGCs improved by means of stiffness; working zones and optimized transition zones can traverse the aortic arch into the common carotid and vertebral arteries from a radial approach including navigation of tortuous and individuated anatomical challenges. Mechanical Thrombectomy improved by balloon occlusion prevents thrombus showers and follows 10 years of interventional cardiology and diagnostic use of improved radial approach (TRA) with better systems, making trans-femoral (TFA)less safe and effective than this revised treatment paradigm, unexpectedly better than literature predicted in early parts of the decade. Likewise, carotid stenting may be performed during these intracranial arterial occlusion procedures without swapping out guide catheters as required by the prior art.

The application discloses a lower limb arterial occlusion segment sharp breakthrough positioning catheter, which comprises a catheter, one end of the catheter is in sealed connection with one end of a joint, the other end of the joint is provided with a guide wire inlet, pressure applying ports A and B are arranged along the longitudinal direction respectively, balloon pressure cavities are arranged on the upper and lower surfaces of the catheter respectively, the balloon pressure cavities are communicated with balloons A and B respectively, and the pressure applying ports A and B are communicated with the balloon pressure cavities; when the sharp breakthrough is performed on the occluded blood vessel segment, the breakthrough point is located at the center of the fiber cap, the sizes of the balloons A and B are controlled by increasing or decreasing the pressure respectively, then the balloons A and B press the guide wire cavity, the angle of the guide wire located in the guide wire cavity is changed, the breakthrough position can be better aligned, after the breakthrough, the front end of a wedge-shaped catheter is applied to perform the breakthrough, the blood flow is smoothly opened after the catheter is introduced, the blood flow opening is more in line with the operation principle, the blood vessel injury caused by the sharp breakthrough is reduced, the operation difficulty is reduced, and the operation success rate is improved.

A system for generating an estimated pulmonary artery occlusion pressure (PAOP) measurement on an ongoing basis, without occlusion of pulmonary arteries, includes one or more sensing devices that produce one or more sensor signals. The system estimates the PAOP measurement based upon the one or more sensor signals from the one or more sensing devices, and displays the estimated PAOP measurement via a display device. In some examples, the system displays an indication of whether the estimated PAOP measurement of a patient is elevated, based upon the estimated PAOP measurement exceeding a predetermined threshold.
