    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.

    Abstract: In one embodiment, a delivery system for a medical device includes a flexible sheath defining a lumen having a distal end and a flexible shaft having a proximal portion and a distal portion. A retention element and a pushing element, spaced proximally from the retention element, are disposed on the distal portion. The flexible shaft, retention element, and pushing element are disposable within the lumen. The flexible shaft is movable distally through the lumen between a stowed position and a deployed position and is movable proximally through the lumen between the deployed position and a partially deployed position with the retention element proximate to the distal end of the lumen. The retention element is configured to form with the medical device an interference fit with the flexible sheath when the flexible shaft is urged proximally from the retention position to engage the medical device with the flexible sheath.
