Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
89 words
A percutaneous filtration catheter, comprising: an elongate member having a proximal end and a distal end; a balloon occluder mounted on the distal end of the elongate member, the balloon defining a chamber which communicates with a lumen carried by the elongate member; and an expandable filter mounted on the elongate member distal the balloon occluder, the expandable filter operable independently of the balloon occluder, the filter having a proximal edge that is fixed to the elongate member, and a distal edge that opens when the filter is operated.
Claim 2
Dependent Claim
89 words
A percutaneous filtration catheter, comprising: an elongate member having a proximal end and a distal end; a balloon occluder mounted on the distal end of the elongate member, the balloon defining a chamber which communicates with a lumen carried by the elongate member; and an expandable filter mounted on the elongate member distal the balloon occluder, the expandable filter operable independently of the balloon occluder, the filter having a proximal edge that is fixed to the elongate member, and a distal edge that opens when the filter is operated.
Claim 3
Dependent Claim
