Abstract
A device useful for treating an aneurysm having a neck comprises 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. The inflatable discs are sized and constructed such that when the inflatable discs are inflated, the aneurysm neck is engaged therebetween. The inflatable discs may include at least one wall that is substantially inelastic and may include an internal member limiting expansion of the inflatable disc in a direction parallel to the device axis. The inflatable discs may have an aspect ratio greater than 3.
Claims10
A device for treating an aneurysm in a blood vessel, the aneurysm having a neck and a sack, 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;
- a pressure controlled one-way valve controlling a fluid communication pathway between the first and second discs and comprising the opening of said valve when the pressure difference between the discs exceeds a predetermined level and the valve pressure control prevents over inflation of the discs;
- wherein said first and second inflatable discs comprise a plurality of webs made from substantially inelastic material extending from one interior side of the disc to the opposing side of the disc so that the webs prevent each inflatable disc from expanding more than a predetermined amount;
- and
- wherein said first and second inflatable discs are sized and constructed such that when one inflatable disc is positioned in the aneurysm sack and said first and second inflatable discs are inflated, the aneurysm neck is engaged there between.
