Abstract
Interventional catheters are disclosed for use in performing diagnostic and therapeutic procedures in vessels that are accessed retrograde to blood flow. The catheters include an elongated shaft slidably disposed within a sheath, a distal region having an end effector and a filter disposed proximal to the end effector to capture emboli liberated during the diagnostic or therapeutic procedure. The filter includes a plurality of struts that cooperate with an exterior surface of the catheter to define a reservoir to retain captured emboli, the reservoir configured so that advancement of the sheath contracts the filter without squeezing or dislodging captured emboli beyond a distal end of the filter.
