Abstract
Abstract An emboli capturing system captures emboli in blood flowing in the vasculature. The emboli capturing system includes a guidewire having a longitudinal axis and defining a lumen along at least a portion thereof. An expandable member is coupled to a distal portion of the guidewire and has an interior being in fluid communication with the lumen in the guidewire. The expandable member is configured to receive fluid through the lumen to expand radially outwardly relative to the guidewire and have fluid removed from the interior thereof to collapse radially inwardly relative to the guidewire. The expandable member, when expanded, has a spaced portion thereof spaced radially outwardly from the guidewire. An emboli capturing device is coupled to the expandable member and is configured to deploy radially outwardly relative to the guidewire upon expansion of the expandable member.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
91 words
An emboli capturing system for introduction into vasculature to capture emboli in blood flowing in the vasculature, the emboli capturing system comprising: a guidewire; an emboli capturing device operably coupled to a distal portion of the guidewire, the emboli capturing device having a first end coupled to the guidewire and a second, expandable end; and a cinch assembly disposed at the second end of the emboli capturing device, the cinch assembly including a cinching actuator extending proximally, actuation of the cinch actuator retracting the second end of the emboli capturing device.
Claim 2
Dependent Claim
91 words
An emboli capturing system for introduction into vasculature to capture emboli in blood flowing in the vasculature, the emboli capturing system comprising: a guidewire; an emboli capturing device operably coupled to a distal portion of the guidewire, the emboli capturing device having a first end coupled to the guidewire and a second, expandable end; and a cinch assembly disposed at the second end of the emboli capturing device, the cinch assembly including a cinching actuator extending proximally, actuation of the cinch actuator retracting the second end of the emboli capturing device.
Claim 3
Dependent Claim
15 words
The emboli capturing system of claim 1 wherein the emboli capturing device comprises a mesh.
Claim 4
Dependent Claim
34 words
The emboli capturing system of claim 1 wherein the guidewire has a lumen extending therethrough and wherein the cinch actuator extends from the second end of the emboli capturing device, proximally through the lumen.
Claim 5
Dependent Claim
18 words
The emboli capturing system of claim 1 wherein the second end of the emboli capturing device opens distally.
Claim 6
Dependent Claim
18 words
The emboli capturing system of claim 1 wherein the second end of the emboli capturing device opens proximally.
Claim 7
Dependent Claim
36 words
The emboli capturing system of claim 1 wherein the guidewire has a lumen extending at least through a distal region thereof and wherein the first end of the emboli capturing device is disposed within the lumen.
Claim 8
Dependent Claim
38 words
The emboli capturing system of claim 1 wherein the cinch assembly includes a plurality of eyelets disposed at the second end of the emboli capturing device and wherein the cinching actuator includes a wire, threaded through the eyelets.
Claim 9
Dependent Claim
28 words
The emboli capturing system of claim 1 wherein the emboli capturing device, when in a collapsed position, has an outer diameter approximating an outer diameter of the guidewire.
Claim 10
Dependent Claim
57 words
The emboli capturing system of claim 1 wherein the emboli capturing device is biased in a collapsed position in which it has an outer diameter approximating the outer diameter of the guidewire, and wherein the emboli capturing device includes an expansion actuator actuable to expand and deploy the emboli capturing device radially outwardly relative to the guidewire.
Claim 11
Dependent Claim
63 words
The emboli capturing system of claim 1 wherein the emboli capturing device is biased in a deployed position in which it is expanded radially outwardly relative to the guidewire, and wherein actuation of the cinching actuator causes the emboli capturing device to move to a retracted position wherein the emboli capturing device has an outer diameter approximating an outer diameter of the guidewire.
