Abstract:
1. A method for treating an aneurysm in a blood vessel, the aneurysm having a neck and a sack, the method comprising: a) providing a device comprising a first inflatable disc and a second inflatable disc, said second inflatable disc being adjacent to said first inflatable disc and in fluid communication therewith wherein said first and second inflatable discs comprise a plurality of webs made from substantially inelastic material and extending in a generally longitudinal direction connecting the inner surfaces of disc walls so that the webs prevent each inflatable disc from expanding more than a predetermined amount; b) positioning the device at an aneurysm such that one inflatable disc is positioned in the aneurysm sack; c) inflating said first and second inflatable discs through a pressure controlled one-way valve controlling the fluid communication between the first and second inflatable discs and comprising said valve opening when the pressure difference between the first and second inflatable discs exceeds a predetermined level and whereby the aneurysm neck is engaged between the first and second disc; and d) utilizing the webs made from substantially inelastic material connecting the inner surfaces of disc walls so that the webs prevent each inflatable disc from expanding more than a predetermined amount.
