Title:
多目的介入冠状動脈ガイドカテーテル
Document Type and Number:
Japanese Patent JP2006528052
Kind Code:
A
Abstract:
A versatile coronary guiding catheter device and methods of use are provided. The device includes a guiding catheter, an anchor shaft, and a sleeve. In one embodiment, the anchor shaft can be moved relative to the catheter body to form a loop defined by the portions of the anchor shaft and catheter body that are between the distal end of the sleeve and a hinge point. The loop engages an interior surface of the aorta in manner effective to facilitate insertion of the distal end of the catheter body into a coronary ostium, to provide backup support for maintaining a position of the distal end of the catheter body within a coronary ostium, or both. The sleeve may also be moveable to increase the control of the loop size and position, to facilitate greater control of the placement of the catheter tip.
