Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 87 words
A system for removing an obstruction from a vessel, comprising: an elongate tubular member having a proximal end and a distal end; and an elongate element having a proximal end, a distal end, and a midsection at least a portion of which is positionable within the elongate tubular member, wherein the distal end of the elongate element includes a capture device operatively connected to the elongate element, wherein the capture device is coated with a thrombogenic material and can assume an expanded condition and a contracted condition.
Claim 2
Independent Claim 87 words
A system for removing an obstruction from a vessel, comprising: an elongate tubular member having a proximal end and a distal end; and an elongate element having a proximal end, a distal end, and a midsection at least a portion of which is positionable within the elongate tubular member, wherein the distal end of the elongate element includes a capture device operatively connected to the elongate element, wherein the capture device is coated with a thrombogenic material and can assume an expanded condition and a contracted condition.
Claim 3
Dependent Claim 14 words
The system of claim 1 , wherein the elongate tubular member is a microcatheter.
Claim 4
Dependent Claim 18 words
The system of claim 1 , wherein the adhesion is at least in part accomplished by fibrin bonds.
Claim 5
Dependent Claim 20 words
The system of claim 1 , wherein the distal end of the elongate element is coated with a thrombogenic material.
Claim 6
Dependent Claim 37 words
The system of claim 1 , wherein the distal end of the elongate element includes a capture device operatively connected to the elongate element, wherein the capture device can assume an expanded condition and a contracted condition.
Claim 7
Dependent Claim 17 words
The system of claim 1 , wherein the capture device is self-deploying and includes knitted superelastic wire.
Claim 8
Dependent Claim 16 words
The system of claim 5 , wherein the capture device is coated with a thrombogenic material.
Claim 9
Dependent Claim 14 words
The system of claim 1 , wherein the capture device includes a mesh-like structure.
Claim 10
Dependent Claim 13 words
The system of claim 5 , wherein the capture device has a pore.
Claim 11
Dependent Claim 19 words
The system of claim 1 , wherein the distal end of the elongate element has a ribbon attached thereto.
Claim 12
Dependent Claim 13 words
The system of claim 10 , wherein the ribbon has a helical shape.
Claim 13
Dependent Claim 21 words
The system of claim 10 , wherein the ribbon is self-deploying and can assume an expanded condition and a contracted condition.
Claim 14
Dependent Claim 15 words
The system of claim 10 , wherein the ribbon is coated with a thrombogenic material.
Claim 15
Independent Claim 105 words
A method for removing an obstruction from a vessel, utilizing a system including a member having a proximal end and a distal end including a capture device coated with a thrombogenic material and being capable of assuming an expanded condition and a contracted condition, comprising the steps of: advancing the system to a treatment site; inserting the distal end of the member into the obstruction and allowing the capture device coated with a thrombogenic material to assume an expanded condition, wherein the distal end promotes adhesion to the obstruction utilizing blood-borne constituents, thereby facilitating removal of the obstruction; and removing the obstruction from a vessel.
Claim 16
Independent Claim 105 words
A method for removing an obstruction from a vessel, utilizing a system including a member having a proximal end and a distal end including a capture device coated with a thrombogenic material and being capable of assuming an expanded condition and a contracted condition, comprising the steps of: advancing the system to a treatment site; inserting the distal end of the member into the obstruction and allowing the capture device coated with a thrombogenic material to assume an expanded condition, wherein the distal end promotes adhesion to the obstruction utilizing blood-borne constituents, thereby facilitating removal of the obstruction; and removing the obstruction from a vessel.
