1. A system for loading a distal protection device, comprising:
- a delivery sheath having a proximal end, a distal end, and a lumen extending though at least a portion of the distal end;
an elongate shaft having a proximal end and a distal end, wherein at least a portion of the shaft is adapted to be disposed within the lumen of the delivery sheath;
a filter disposed proximate the distal end of the shaft; and
a loading tool for loading the filter into the delivery sheath, the loading tool having a proximal end, a distal end, and a lumen extending therethrough adapted to receive at least a portion of the filter, wherein at least a portion of the loading tool is configured to be coupled to the delivery sheath.

6. A method of loading a filter, comprising the steps of:
-
providing a sterile package including a delivery sheath, an elongate shaft having a filter disposed proximate a distal end thereof, and a loading tool;
removing the delivery sheath from the sterile package;
removing the loading tool from the sterile package;
coupling the loading tool to a delivery sheath;
removing the shaft from the sterile package;
loading the filter within the delivery sheath by applying force to the elongate shaft, wherein the filter passes through a lumen within the loading tool and into a lumen within the delivery sheath; and
separating the loading tool from the delivery sheath.

21. A method of loading a filter, comprising the steps of:
-
providing a loading tool having a proximal end, a distal end, and a lumen extending therethrough;
providing an elongate shaft having a filter disposed proximate a distal end thereof, wherein the filter is configured to be disposed with the lumen of the loading tool and in an expanded configuration;
coupling the loading tool to a delivery sheath having a proximal end, a distal end, and a lumen extending through at least a portion of the distal end;
urging the filter toward the proximal end of the loading tool by applying force to the elongate shaft, wherein the filter shifts from the expanded configuration to a collapsed configuration; and
urging the filter to within the lumen of the delivery sheath. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
