摘要： A method of delivering a catheter to a location of interest in the vasculature, the method including positioning a self-expanding sheath within a lumen of the catheter; advancing the catheter and the self-expanding sheath in tandem over a guidewire; and distally moving a distal end of the self-expanding sheath out from the lumen of the catheter thereby causing the self-expanding sheath to move from a collapsed state within the catheter to an expanded state outside the catheter, wherein when the self-expanding sheath is in the expanded state both the self-expanding sheath and the catheter are distally advanceable in tandem.

摘要： Devices can generally include a fan portion for occluding an aneurysm neck, a channel orifice opening in the fan portion, and an agent channel for delivering a coagulating agent through the orifice into the aneurysm. Devices can be delivered through a catheter to the aneurysm, the fan portion can expand to occlude the aneurysm neck, and coagulating agent can be injected into the aneurysm. During injection of the coagulating agent, the fan portion can inhibit the coagulating agent from exiting the aneurysm. After injection of the coagulation agent, the fan portion can collapse and the device can be extracted from the patient.
