Abstract:
1. A method of intubating a branch vessel in a patient, the vessel having an ostium, a lumen and a lumen wall, the method comprising the following steps in order: receiving a guiding catheter comprising an elongate hollow shaft having open proximal and distal ends and a resiliently compressible occluder sealingly fixed about the shaft adjacent the distal end and having a relaxed size and shape including a major diameter greater than a diameter of the lumen, the shaft lacking structure for fluid or mechanical actuation of the occluder from the shaft proximal end; inserting an introducer sheath into a vascular system of the patient; manually compressing the occluder into a compressed configuration capable of being inserted into the introducer sheath; inserting the catheter shaft distal end through the introducer sheath into the vascular system of the patient until the occluder enters the vascular system and resiliently expands to the relaxed size and shape; advancing the catheter shaft distal end to the branch vessel in the patient; intubating the vessel with the catheter shaft distal end; and wedging the compressible occluder into the vessel lumen such that the major diameter of the occluder passes beyond the vessel ostium to compress the occluder into sealing engagement with the wall of the vessel lumen to provide temporary hemostasis.
