Patent ID: 7892254

Claim:
A method for endovascular occlusion of a blood vessel area, comprising: advancing a catheter percutaneously and transluminally until a distal opening of said catheter is located at a blood vessel area to be occluded; providing a wire body comprising a front end, a back end, and a section connecting said front end and said back end, wherein said section is substantially straight in a predetermined unloaded shape, a length of said section being larger than a diameter of said blood vessel area; inserting said wire body into said catheter, said section of said wire body being substantially in said predetermined unloaded shape within said catheter; mechanically pushing said wire body forward through said catheter until said front end of said wire body is pushed out of said distal opening of said catheter; abutting a first wall portion of said blood vessel area with said front end of said wire body, thereby column loading said wire body and frictionally locking said front end against said first wall portion; continuing to mechanically push said wire body out of said distal opening of said catheter, thereby curving said section of said wire body toward a second wall portion of said blood vessel area, wherein said section of said wire body frictionally locks against said second wall portion of said blood vessel area when said section is column loaded between said first and second wall portions due to said wire body being mechanically pushed forward, thereby forming a portion of said wire body crossing said blood vessel area that is frictionally locked to said first wall portion and said second wall portion due to said column loading; physically separating said wire body from said catheter by pushing an entirety of said wire body out of said distal opening of said catheter; occluding blood flow in said blood vessel area to be occluded using said section of said wire body frictionally locked between said first and second wall portions, wherein said blood flow is occluded after said wire body is physically separated from said catheter and after said catheter is removed from said blood vessel area to be occluded; and forming a thrombus at a location of said wire body after said wire body is physically separated from said catheter and after said catheter is removed from said blood vessel area to be occluded.
