US 2023/0397930 A1 · BALLOON GUIDE CATHETER FOR RADIAL ACCESS

Abstract

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.

Dependent claims

A system for radial access to, and ingress through the supra-aortic arch to select supra-aortic branches, which comprises, in combination:

an intravascular catheter having a proximate and a distal end, a compliant balloon positioned closer to the distal end of the catheter between a working zone and a transition zone along said intravascular catheter;
a protector section, a connector, a balloon aspiration port, an injection lumen port;
and
radiopaque markers likewise functionally connected upon the intravascular catheter.

1 more element

A process for using an improved rBGC for treating intracranial arterial occlusions, which comprises at least the steps of:

providing a thin walled radial sheath housing an intravascular rBGC;
inserting the sheath into the radial artery following infusion of a predetermined anti-clotting, anti-inflammatory and anti-vasospasm mixture into the patient subcutaneously, and connecting the patient to a heparin-drip;
navigating the rBGC triaxially over an access catheter, being longer than at least about 120 cm, over a wire being between at least about 0.035 and 0.038 in diameter into position within the supra-aortic arch;
using the access catheter to select at least one vessel from the group of supra-aortic main branches consisting essentially of the Common Carotid Artery (CCA) and the Vertebral Artery (VA);
navigating the wire up the vessel of interest under fluoroscopic guidance, followed by the access catheter and then the rBGC until positioned in place for intervention;
removing the wire and access catheter leaving the rBGC in place in the vessel of interest;
navigating any endovascular thrombectomy device inside the rBGC to perform thrombectomy;
inflating the balloon on the rBGC with 50% contrast and 50% saline to arrest flow during thrombus removal via balloon aspiration/inspiration port;
applying aspiration to the main lumen of the rBGC once thrombus removed to remove any other debris from the thrombectomy preventing distal emboli;
and
deflating the balloon by application of aspiration/suction via the balloon aspiration/inspiration port
