PRE-CURVED GUIDING CATHETER WITH ECCENTRIC BALLOON FOR SUPPLEMENTAL BACKUP SUPPORT

摘要

A guiding catheter includes an elongate shaft with a main lumen and a pre-shaped curve adjacent the distal end of the shaft. The pre-shaped curve is sized and shaped for positioning in a main vessel to provide intubation of a branch vessel with a distal end of the catheter. An eccentric balloon is disposed on the shaft for selective inflation against a wall of the main vessel opposite the entrance into the branch vessel to provide supplemental backup support during interventional catheterization of the branch vessel. Methods of using the guiding catheter are also disclosed.
