<p><P>PROBLEM TO BE SOLVED: To provide an improved vascular occlusion device for occlusion of a passageway such as a blood vessel, a chamber and a channel, a cavity or the like, which may give improved flexibility, improved retaining force and improved thrombogeneity. <P>SOLUTION: A medical device 10 includes a first portion having at least one plane of occlusion that is configured to be positioned outside of the left atrial appendage, and a second portion having at least one plane of occlusion that is configured to be at least partially positioned within a cavity defined by the left atrial appendage. The medical device may include a first portion (e.g. a disk portion 14) having a first diameter and a second portion (e.g. a cylindrical portion 12) having a second diameter. The medical device may include a transition section 19, which connects the first portion and the second portion, and is configured to give flexibility between the portions. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
