Abstract
Abstract The devices and methods of the invention are directed to various aspects of removing obstructions in a blood vessel. A power source may be provided to facilitate advancement of the device and engagement with the obstruction. The obstruction removal device may have alternating large and small sections or may have one or more loops. In another aspect, the obstruction removal device may have alternating sections wound with filament and substantially exposed sections.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
151 words
A method of removing an obstruction, comprising the steps of: providing an obstruction removing device, the obstruction removing device having an element movable from a collapsed position to an expanded position, the element being contained within a lumen in a delivery device in the collapsed position; advancing the delivery device through the patient's vascular system to an obstruction in a vessel; expanding at least part of the engaging element toward the expanded position; coupling the engaging element to a supply of power; moving the engaging element into contact with the obstruction; supplying power to the element when the engaging element is in contact with the obstruction, wherein the power supplied to the engaging element causes the obstruction to be at least partially adhered to the engaging element; and removing the obstruction from the blood vessel with the engaging element while the obstruction is at least partially adhered to the engaging element.
Claim 2
Independent Claim
151 words
A method of removing an obstruction, comprising the steps of: providing an obstruction removing device, the obstruction removing device having an element movable from a collapsed position to an expanded position, the element being contained within a lumen in a delivery device in the collapsed position; advancing the delivery device through the patient's vascular system to an obstruction in a vessel; expanding at least part of the engaging element toward the expanded position; coupling the engaging element to a supply of power; moving the engaging element into contact with the obstruction; supplying power to the element when the engaging element is in contact with the obstruction, wherein the power supplied to the engaging element causes the obstruction to be at least partially adhered to the engaging element; and removing the obstruction from the blood vessel with the engaging element while the obstruction is at least partially adhered to the engaging element.
Claim 3
Dependent Claim
26 words
The method of claim 1 , wherein: the coupling step is carried out with the supply of power producing an electrical charge at the engaging element.
Claim 4
Dependent Claim
26 words
The method of claim 2 , wherein: the coupling step is carried out with the supply of power producing a negative charge during the moving step.
Claim 5
Dependent Claim
26 words
The method of claim 2 , wherein: the coupling step is carried out with the supply of power producing a positive charge during the supplying step.
Claim 6
Dependent Claim
22 words
The method of claim 1 , wherein: the coupling step is carried out with the supply of power being an RF generator.
Claim 7
Dependent Claim
24 words
The method of claim 1 , wherein: the providing step is carried out with the engaging element being naturally biased toward the expanded position.
