Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 93 words
A device for containing emboli within an atrial appendage of a patient, comprising: an expandable frame comprising a plurality of supports projecting distally from a proximal hub toward a distal end, wherein the supports comprise proximal sections adjacent to said proximal hub, wherein at least one of said proximal support sections curves distally, then proximally, and then distally toward said distal end; a membrane provided on said proximal sections of supports; and a plurality of tissue anchors provided on said supports for engaging tissue when the device is positioned in an atrial appendage.
Claim 2
Independent Claim 93 words
A device for containing emboli within an atrial appendage of a patient, comprising: an expandable frame comprising a plurality of supports projecting distally from a proximal hub toward a distal end, wherein the supports comprise proximal sections adjacent to said proximal hub, wherein at least one of said proximal support sections curves distally, then proximally, and then distally toward said distal end; a membrane provided on said proximal sections of supports; and a plurality of tissue anchors provided on said supports for engaging tissue when the device is positioned in an atrial appendage.
Claim 3
Dependent Claim 26 words
A device as in claim 1 , wherein at least one of said distally then proximally then distally curved proximal support sections comprises generally an S-shape.
Claim 4
Dependent Claim 16 words
A device as in claim 1 , wherein the expandable frame comprises at least five supports.
Claim 5
Dependent Claim 38 words
