Embolic protection system
First Claim
1. An assembly for loading an embolic protection filter into a catheter, the assembly comprising:
- an embolic protection filter comprising a sleeve extending from a proximal end of the embolic protection filter to a distal end of the embolic protection filter, the sleeve having a lumen extending at least partially therethrough;
a catheter defining a reception space for receiving the embolic protection filter;
an urging device for delivering the embolic protection filter into the reception space; and
a loading device to collapse the embolic protection filter, whereinthe loading device comprises an inlet end and an outlet end, the outlet end being configured for co-operative alignment with the reception space,the urging device is removable from the embolic protection filter, while the embolic protection filter remains in the reception space, andthe urging device comprises an engagement formation having a radial dimension that is greater than a radial dimension of the lumen of the sleeve and a stem for insertion through at least part of the lumen of the sleeve.

Abstract
An assembly for loading a collapsible embolic protection filter 1 into a catheter 2, comprises a catheter 2 defining a reception space at a distal end of the catheter 2 for receiving a collapsed embolic protection filter 1; and a separate removable pushing device 8 for delivering the embolic protection filter 1 into the reception space. The pushing device 8 comprises an elongate stem 71 with a proximal stop 72 for engagement with the filter 1. A separate loading device 7 to collapse the embolic protection filter 1 is also provided. The loading device 7 defines an inlet end and an outlet end, the outlet end being configured for co-operative alignment with the reception space.

5. A method of loading an embolic protection filter into a catheter, the method comprising the steps of:
-
providing an embolic protection filter comprising a sleeve extending from a proximal end of the embolic protection filter to a distal end of the embolic protection filter, the sleeve having a lumen extending at least partially therethrough; providing a catheter defining a reception space; providing an urging device comprising an engagement formation having a radial dimension that is greater than a radial dimension of the lumen of the sleeve and a stem for insertion through the lumen of the sleeve; providing a loading device comprising an inlet end and an outlet end being configured for alignment with the reception space, wherein the loading device is used to collapse the filter delivering the embolic protection filter into the reception space using the urging device; and removing the urging device from the filter, while the embolic protection filter remains in the reception space. - View Dependent Claims (6, 7)
