Abstract
A self-expanding implantable medical device formed from one or more non-interlocking filaments. Stents, stent-grafts, occluder devices, and filters are manufactured from one or more filaments utilizing a non-interlocking crossing pattern.
Claims33
An implantable device comprising
- a self-expanding structure having a crossing pattern of at least one filament;
- wherein the crossing pattern is non-interlocking.
An implantable device comprising
- at least one filament forming multiple layers of a self-expanding tubular structure;
- wherein an innermost layer of the tubular structure consists of a single winding of the filament forming a full revolution of the tubular structure that does not cross over itself.
An implantable device comprising
- a diametrically expandable tubular structure made of at least one filament wherein said filament has a multiplicity of length portions separated by apices wherein the filament is bent to form each of said apices;
- wherein said length portions are arranged in two directions such that a first group of said length portions are oriented at an angle to a second group of said length portions;
- wherein said length portions of said first group cross multiple length portions of said second group such that a length portion of said first group either crosses over or under a length portion of said second group;
- and
- wherein a length portion of said first group crosses over a number of length portions of said second group that is a different number than that crossed over by an adjacent length portion of said first group.
