Embolic protection device
View Patent ↗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.
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.
