Abstract

An embolic protection filter. In some embodiments, the device includes an elongate shaft, a filter coupled to the shaft, and a proximal stop coupled to the shaft.

Claims

1. An embolic protection filtering device, comprising:

an elongate shaft having a proximal end, a distal end and a distal portion, the elongate shaft extending through at least a portion of a catheter lumen;

a first stop coupled to the distal portion of the elongate shaft;

a second stop coupled to the distal portion of the elongate shaft distal of the first stop;

a tube slidably disposed over the distal portion of the elongate shaft intermediate the proximal stop and the distal stop;

an embolic protection filter coupled to the tube; and

a third stop attached to the tube, wherein the third stop is configured to restrain longitudinal movement of a catheter distal of the third stop.

2. An embolic protection filtering device, comprising:

an elongate shaft having a proximal end and a distal end;

a catheter disposed on the elongate shaft;

an embolic protection filter coupled to the elongate shaft at a first location and a second location; and

a stop coupled to the elongate shaft intermediate the first location and the second location, the stop configured to restrain the catheter from advancing distally of the stop.
