An embolic capturing device for capturing emboli within a body lumen is disclosed. The embolic capturing device (10) comprises a filtering basket (20) and at least one coil (22) attached to the basket. The filtering basket includes a frame (23) and a filtering body (30) disposed on the frame. The at least one coil is attached to the filtering body for filtering emboli in the body lumen.
1. An embolic capturing device for capturing emboli within a lumen, the device comprising: a basket including a frame and a filtering body disposed on said frame, the basket being configured to have an expanded state and a collapsed state, the filtering body defining a filter volume when the basket
1. An embolic capturing device for capturing emboli within a lumen, the device comprising: a basket including a frame and a filtering body disposed on said frame, the basket being configured to have an expanded state and a collapsed state, the filtering body defining a filter volume when the basket is in the expanded state, the frame comprising a plurality of struts; andat least one coil separate from the filtering body and having a helical winding, the at least one coil attached to one strut of the basket, the at least one coil fixedly extending radially across the basket and across the filter volume from one strut to another strut and fixedly attached to the another strut for capturing emboli when the basket is in the expanded state. 2. The device of claim 1 further comprising the frame having first and second portions, the filtering body having a lip disposed on the second portion of the frame to define an opening of the filtering body when the basket is in the expanded state for capturing emboli, the filtering body extending from the lip to a filter end. 3. The device of claim 2 wherein the filtering body is disposed on the second portion of the frame. 4. The device of claim 1 wherein the at least one coil comprises a plurality of coils. 5. The device of claim 1 further comprising a tubular shaft having a shaft body extending to a distal portion, the shaft body having slits formed longitudinally therethrough to the distal portion, the slits defining said plurality of struts forming the frame of the basket. 6. The device of claim 5 wherein the tubular shaft is formed of a malecot configuration, the second portion of the frame being integral with the distal portion and the first portion being integral with the shaft body to define the malecot configuration. 7. The device of claim 2 further comprising a tubular shaft having proximal and distal ends, the distal end being connected to the first portion of the frame for delivery and retrieval of the device. 8. The device of claim 7 further comprising the plurality of struts including at least one pair of opposed struts being integrally formed, each pair of struts being configured to distally extend from the proximal end of the tubular shaft to the second portion and further extend oppositely to the proximal end, defining the basket. 9. The device of claim 1 further comprising a filtering body of super-elastic material, connective tissue material, shape memory alloy, aluminum, platinum, metal alloy, nylon, polymeric material, polytetrafluoroethylene, or a mixture thereof. 10. The device of claim 1 wherein the struts are formed of a super-elastic material or a shape memory alloy. 11. The apparatus of claim 7 wherein the tubular shaft further includes a balloon formed thereon for stenosis procedure. 12. A method for capturing emboli within a body vessel, the method comprising: percutaneously introducing an embolic capturing device for capturing emboli during a stenosis procedure at a stenotic area, the embolic capturing device including: a basket including a frame and a filtering body attached within the frame, the filtering body defining a filter volume, the frame having first and second portions; andat least one coil having a helical winding, the at least one coil fixedly attached to one strut of the basket and extending radially across the basket and across the filter volume to another strut and fixedly attached to the another strut for filtering emboli in a body lumen;disposing the embolic capturing device through the stenotic area; anddeploying the embolic capturing device in the body vessel to capture emboli. 13. An embolic capturing device for capturing emboli within a lumen, the device comprising: a basket including a frame and a filtering body disposed on said frame, the basket being configured to have an expanded state and a collapsed state, the filtering body defining a filter volume when the basket is in the expanded state, the frame comprising a plurality of struts; andat least one coil separate from the filtering body and wound into a primary coil body having a first helical winding, the primary coil body further wound into a secondary coil body having a second helical winding, the at least one coil fixedly attached to one strut of the basket, the at least one coil extending radially across the basket and across the filter volume from one strut to another strut and fixedly attached to the another strut for capturing emboli when the basket is in the expanded state. 14. The device of claim 13 further comprising the frame having first and second portions, the filtering body having a lip disposed on the second portion of the frame to define an opening of the filtering body when the basket is in the expanded state for capturing emboli, the filtering body extending from the lip to a filter end. 15. The device of claim 14 wherein the filtering body is disposed on the second portion of the frame. 16. The device of claim 13 further comprising a tubular shaft having a shaft body extending to a distal portion, the shaft body having slits formed longitudinally therethrough to the distal portion, the slits defining said plurality of struts forming the frame of the basket. 17. The device of claim 16 wherein the tubular shaft is formed of a malecot configuration, the second portion of the frame being integral with the distal portion and the first portion being integral with the shaft body to define the malecot configuration. 18. The device of claim 14 further comprising a tubular shaft having proximal and distal ends, the distal end being connected to the first portion of the frame for delivery and retrieval of the device. 19. The device of claim 18 further comprising the plurality of struts including at least one pair of opposed struts being integrally formed, each pair of struts being configured to distally extend from the proximal end of the tubular shaft to the second portion and further extend oppositely to the proximal end, defining the basket. 20. The device of claim 13 further comprising a filtering body of super-elastic material, connective tissue material, shape memory alloy, aluminum, platinum, metal alloy, nylon, polymeric material, polytetrafluoroethylene, or a mixture thereof.
