Methods and devices for reducing or blocking blood flow to a selected blood vessel or part thereof
First Claim
1. A method of reducing or blocking blood flow to a selected blood vessel, or a selected part of a wall thereof, particularly for treating an aneurysm, an arteriovenous malformation, or a dural malformation, or for devascularizing a blood vessel feeding the tumor, such method comprising:
- deploying in the selected blood vessel an expandable member having a contracted condition for manipulation within the blood vessel, and expandable to an expanded condition in the blood vessel for reducing or blocking blood flow through the blood vessel or the selected part of the wall thereof, and thereby to promote coagulation of blood within the selected blood vessel or part of the wall thereof;
and applying a local stimulus to the interior of the selected blood vessel or part of the wall thereof effective to initiate or accelerate coagulation of blood therein.

Abstract
A method of reducing or blocking blood to a selected blood vessel or a selected part of the wall thereof, particularly for treating an aneurysm, an arteriovenous or dural malformation in a blood vessel, or for devascularizing tumors, by deploying in the blood vessel an expandable member having a contracted condition for manipulation within the blood vessel, and expandable to an expanded condition in the blood vessel for reducing or blocking blood flow through the selected part thereof, thereby promoting coagulation of blood therein, and for preventing thrombus material from being swept downstream, and applying a local stimulus to the interior of the malformation effective to initiate or accelerate coagulation of blood therein. In some described embodiments, the expandable member is a permeable mesh-like tube of biocompatible material, and in other described embodiments, the expandable member is an inflatable balloon.

22. A kit for use in reducing or blocking blood flow to a selected blood vessel, or a selected part or a wall thereof, particularly for treating an aneurysm, an arteriovenous malformation, or a dural malformation, or for devascularizing a blood vessel feeding a tumor, said kit comprising:
-
an expandable member having a contracted condition for manipulation within the blood vessel and expandable to an expanded condition within the blood vessel for reducing or blocking blood flow to the selected part of the blood vessel or wall thereof, and thereby to promote coagulation of blood therein; and a local stimulus applicator for applying a local stimulus to the interior of the selected part of the blood vessel, such as to initiate or accelerate coagulation of blood therein. - View Dependent Claims (23, 25, 26, 27, 28, 30)
