Abstract

Distal protection filter frame and method for using and manufacturing the same. A distal protection filter frame may include one or more struts, a mouth, and a filter coupled to the mouth.

Claims

1. A method of manufacturing a distal protection filter assembly, comprising the steps of:

providing a filter frame having a plurality of struts and a filter body section;

providing a mandrel having a longitudinal axis, a proximal region, a middle region, and a distal region, the middle region having a groove formed therein that extends about the longitudinal axis of the mandrel;

coupling the filter frame to the mandrel wherein at least a portion of the body section is disposed within the groove;

coupling filter material to at least a portion of the filter frame; and

wherein the mandrel includes one or more strut channels and a guidewire channel, and wherein the step of coupling the filter frame to the mandrel includes passing the struts through the strut channels and into the guidewire channel.
