1. An embolic protection filter assembly, comprising;
- an outer sheath having a proximal end, a distal end, and a lumen extending therethrough;
an elongate shaft disposed in at least a portion of the lumen, the shaft having a distal end;
an embolic protection filter coupled to the shaft near the distal end thereof; and
a tapering member coupled to the sheath and disposed near the distal end of the sheath, the tapering member being adapted and configured to shift between a first position and a second position, such that when the tapering member is in the first position, the tapering member provides the outer sheath with a tapered distal tip.

18. An embolic protection filter assembly, comprising;
-
an outer sheath having a proximal end, a distal end, a lumen extending therethrough, and a longitudinal axis;
a rounded distal head disposed at the distal end, the rounded distal head having an opening;
wherein the opening is in fluid communication with the lumen and oriented in a direction that is skewed relative to the longitudinal axis of the sheath;
an elongate shaft disposed in at least a portion of the lumen, the shaft having a distal end; and
an embolic protection filter coupled to the shaft near the distal end of the shaft.
