Title: Thrombus filter with break-away anchor members
Inventor: DIMATTEO KRISTIAN
IPC: A61B17/12
Filed: 2001-01-23
Abstract: 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 thromb us 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 tha t the thrombus filter is generally conical in shape. The free end of each stru t 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 ar e 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 fr om the blood vessel.
