High radiopacity is achieved in a polymeric marker by combining a polymeric resin, a powdered radiopaque agent having uniformly shaped particles of a specific particle size distribution and a wetting agent. The method to produce the marker calls for the blending and pelletization of these materials followed by extrusion onto support beading. The resulting supported tubing is subsequently cut to length with the beading still in place. After ejection of the beading remnant the marker is slipped into place on the device to be marked and attached by melt bonding. Marking of a guidewire allows lesions to be measured while the marking of balloon catheters allow the balloon to be properly positioned relative to a lesion.

A locking component for locking a medical device onto a guide wire. Such medical devices include, for example, an embolic filter assembly used to capture embolic material that may be created and released into a patient's vasculature during a stenting or angioplasty procedure. The embolic filter assembly tracks along the guide wire, and is delivered to a treatment site where it is locked in place and deployed. The locking component enables the filter assembly to lock onto any standard guide wire, and does not require a modified guide wire that has a specially-designed fitting or stop to accomplish the locking function.
