This invention relates to medical devices for manipulating medical implants such as, for example, stents, distal protection filters, and septal occluders in a patient's body, and the methods of use thereof. Generally, a medical device of the invention includes a sleeve and an expandable component joined to the sleeve which transitions between a collapsed configuration and a deployed configuration for capturing a medical implant in a patient's body.

What is claimed is: 1. A method for capturing a cardiovascular implant that has been implanted previously at an anatomical site in a patient's body comprising the steps of: providing a medical device comprising a sleeve comprising a lumen, a distal end and a proximal end and an expandable component

What is claimed is: 1. A method for capturing a cardiovascular implant that has been implanted previously at an anatomical site in a patient's body comprising the steps of: providing a medical device comprising a sleeve comprising a lumen, a distal end and a proximal end and an expandable component, wherein at least a portion of the expandable component is permanently joined to the distal end of the sleeve, the expandable component transitioning between a collapsed configuration wherein the expandable component is enclosed by the sleeve, and a deployed configuration wherein at least a portion of the expandable component that was enclosed by the sleeve while in the collapsed configuration expands to a size for capturing the cardiovascular implant upon extending beyond the distal end of the sleeve; advancing the medical device to an anatomical site in a patient's body where the cardiovascular implant has been implanted previously; and transitioning the expandable component from the collapsed configuration to the deployed configuration such that at least a portion of the expandable component that was enclosed by the sleeve extends beyond the distal end of the sleeve while the expandable component remains permanently joined to the distal end of the sleeve, thereby surrounding and capturing with the expandable component the cardiovascular implant that has been implanted previously. 2. The method of claim 1, wherein the cardiovascular implant is a distal protection filter. 3. The method of claim 1, wherein the medical device further comprises an elongate member slideably moveable within the lumen of the sleeve. 4. The method of claim 1, wherein the expandable component is reciprocally moveable relative to the sleeve. 5. The method of claim 1, wherein the sleeve is reciprocally moveable relative to the expandable component. 6. The method of claim 1, wherein the cardiovascular implant is a septal occluder. 7. The method of claim 1, wherein the cardiovascular implant is a stent. 8. The method of claim 1, further comprising the step of removing the cardiovascular implant and the medical device from the patient. 9. The method of claim 1, where the expandable component is conical in shape.
