Abstract
Abstract A balloon arterial cannula and methods for filtering blood. The devices generally include a mesh for filtering blood flowing within a blood vessel, particularly within an artery such as the aorta, a structure adapted to open and close the mesh within the blood vessel, a means to actuate the structure, and a balloon occluder which typically includes a flexible material enclosing a chamber. The methods generally include the steps of introducing a mesh into a blood vessel to capture embolic material, adjusting the mesh, if necessary, during the course of filtration, inflating the balloon occluder to occlude the vessel upstream of the mesh, and thereafter deflating the balloon occluder and removing the mesh and the captured foreign matter from the blood vessel. Additionally, visualization techniques are used to ensure effective filtration.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
39 words
A cannula, comprising: an elongate tubular member having a proximal end, a distal end, and a lumen therebetween; a filter separately insertable through the elongate tubular member; and an expandable occluder deployable from the distal region of the cannula.
Claim 2
Dependent Claim
39 words
A cannula, comprising: an elongate tubular member having a proximal end, a distal end, and a lumen therebetween; a filter separately insertable through the elongate tubular member; and an expandable occluder deployable from the distal region of the cannula.
Claim 3
Dependent Claim
15 words
The cannula of claim 1 , further comprising a separate channel within the tubular member.
Claim 4
Dependent Claim
15 words
The cannula of claim 2 , wherein the filter is insertable through the separate channel.
Claim 5
Dependent Claim
14 words
The cannula of claim 1 , wherein the expandable occluder is a balloon occluder.
Claim 6
Dependent Claim
28 words
The cannula of claim 4 , wherein the balloon communicates with an inflation lumen connectable to an external fluid source near a proximal end of the inflation lumen.
Claim 7
Dependent Claim
22 words
The cannula of claim 1 , wherein the cannula is a blood cannula adapted to pass oxygenated blood for cardiopulmonary bypass procedures.
Claim 8
Dependent Claim
18 words
The cannula of claim 1 , wherein the occluder is mounted on the distal end of the cannula.
Claim 9
Dependent Claim
15 words
The cannula of claim 1 , wherein the distal end of the cannula is straight.
Claim 10
Dependent Claim
15 words
The cannula of claim 1 , wherein the distal end of the cannula is curved.
Claim 11
Dependent Claim
14 words
The cannula of claim 1 , further comprising a windsock that diverts blood flow.
Claim 12
Independent Claim
45 words
A method for cannulation, comprising the steps of: inserting a distal end of a cannula into a patient; inserting a filter through a lumen of the cannula into the patient; deploying the filter; and expanding an occluder associated with the distal end of the cannula.
Claim 13
Independent Claim
45 words
A method for cannulation, comprising the steps of: inserting a distal end of a cannula into a patient; inserting a filter through a lumen of the cannula into the patient; deploying the filter; and expanding an occluder associated with the distal end of the cannula.
Claim 14
Dependent Claim
14 words
The method of claim 11 , wherein the cannula is inserted into a vessel.
Claim 15
Dependent Claim
12 words
The method of claim 12 , wherein the vessel is an aorta.
