Title:
再灌流カテーテルシステム
Document Type and Number:
Japanese Patent JP2013528106
Kind Code:
A
Abstract:
A reperfusion catheter system with an introducer sheath having an inner wall defining a longitudinal opening extending from a proximal portion to a distal end. A balloon catheter has an outer wall and has a longitudinal opening extending from a proximal portion to a distal end. The balloon catheter is disposed through the opening in the introducer sheath, and the balloon catheter has an inflatable balloon at the distal end. A conduit has a first end disposed in fluid communication with the area inside the introducer sheath between the inner wall of the introducer sheath and the outer wall of the balloon catheter. The conduit also has a second end disposed in fluid communication with the inside of the balloon catheter. The invention provides for the establishment of artificial antegrade blood flow in the lumen of a target vessel through a path between the outer wall of the balloon catheter and the inner wall of the introducer sheath, through the conduit, through the opening in the balloon catheter, and exiting through the distal end of the balloon catheter. When the occlusion balloon is inflated, there is no back flow in the target vessel and, as the artificial antegrade flow takes place, there is full control of the target vessel blood flow and as a result a significant increase in the safety of the embolization procedures.
