Abstract
A filter comprising a porous material is arranged in a generally conical shape having an expandable base and a vertex. An elongate member having a proximal end and a distal end is attached to the expandable base of the porous material at a first circumferential location of the expandable base and extends perpendicularly from a central axis of the filter. An aspiration tube, for removing embolic material under vacuum, communicates with an area at the first circumferential location of the expandable base. Methods of using the filter and occluding devices for protecting a patient from embolization during cardiovascular procedures are described.
Claims20
A filter, comprising:
- a porous material arranged in a generally conical shape having an expandable base and a vertex;
- an elongate member having a proximal end and a distal end attached to the expandable base of the porous material at a first circumferential location of the expandable base and extending perpendicularly from a central axis of the filter;
- and
- an aspiration tube having a proximal end, a distal end, and a lumen therebetween, the lumen communicating with a port at the distal end, the distal end of the aspiration tube communicating with an area at the first circumferential location of the expandable base.
A method for protecting a patient from embolization, comprising the steps of:
- inserting a filter into the patient's aorta, the filter comprising a porous material arranged in a generally conical shape having an expandable base and a vertex, an elongate member having a proximal end and a distal end attached to the expandable base of the porous material at a first circumferential location of the expandable base and extending perpendicularly from a central axis of the filter, and an aspiration tube having a proximal end, a distal end, and a lumen therebetween, the lumen communicating with a port at the distal end, the distal end of the aspiration tube communicating with an area at the first circumferential location of the expandable base;
- expanding the filter;
- aspirating emboli through the suction port, wherein embolic material is removed from the aorta;
- and
- collapsing the filter and removing the filter form the aorta.
