A thrombus filter which can be securely fixed at a selected location in the vascular system of a patient and removed when no longer required. The thrombus filter includes a body portion and a plurality of struts, each strut having a joined end and a free end. The joined end of each strut is fixably attached to the body portion. The struts radiate outwardly from the body member such that the thrombus filter is generally conical in shape. The free end of each strut includes an anchor member. A weakened portion is disposed proximate the free end of each strut. When removal of the thrombus filter is desired, forces are applied to the thrombus filter causing the struts to break at the weakened portions proximate the free ends. When breaking of the struts has been accomplished, the thrombus filter may be freely pulled into the lumen of the retrieval catheter. Once the thrombus filter is disposed inside the lumen of the retrieval catheter, the removal of the thrombus filter from the body of the patient becomes a simple matter of withdrawing the retrieval catheter from the blood vessel.
L'invention concerne un filtre à thrombus pouvant être fixé en un point choisi du système vasculaire et retiré au moment voulu, qui comprend un corps et plusieurs montants présentant chacun une extrémité reliée et une extrémité libre. L'extrémité reliée est fixée au corps. Les montants s'étendent vers l'extérieur du corps, et le filtre a ainsi une forme conique. L'extrémité libre comprend un élément de fixation. Une partie affaiblie est placée à proximité de l'extrémité libre. Au moment du retrait, on applique des forces au filtre, rompant ainsi les montants sur la partie affaiblie proche de l'extrémité libre. Ensuite, le filtre peut être retiré librement à travers la lumière du cathéter d'extraction. Une fois dans ladite lumière, le filtre peut être extrait simplement par récupération du cathéter.
