Abstract
Abstract This invention is an occlusive device for inserting into body cavities or vesicles. More particularly, it is a vasoocclusive device which, as used, is in the approximate shape of an anatomical cavity. It may be ultimately deployed as a substantially spherical shape in the operable configuration. The device is a self-forming shape made from a pre-formed occlusive strand of flexible material. The occlusive strand may be helically coiled or braided and may be adapted with various polymeric fibers. The device is typically introduced through a catheter in the substantially linear inoperable configuration. The invention provides a plurality of such substantially spherical strand portions which nest concentrically with each other in the operable configuration. The invention also includes methods of producing and using the substantially spherical vasoocclusive devices.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
68 words
An occlusive device comprising at least one strand of a flexible material movable between an inoperable substantially linear configuration for insertion into and through a means for delivering the device to a desired portion of a vesicle, and an operable, substantially spherical configuration being substantially hollow for occluding at least a portion of said vesicle, said substantially spherical configuration assuming a substantially minimal energy configuration for said strand.
Claim 2
Dependent Claim
68 words
An occlusive device comprising at least one strand of a flexible material movable between an inoperable substantially linear configuration for insertion into and through a means for delivering the device to a desired portion of a vesicle, and an operable, substantially spherical configuration being substantially hollow for occluding at least a portion of said vesicle, said substantially spherical configuration assuming a substantially minimal energy configuration for said strand.
Claim 3
Dependent Claim
78 words
An occlusive device comprising at least one strand of a flexible materal movable between an inoperable substantially linear configuration for insertion into and through a means for delivering the device to a desired portion of a vesicle, and an operable substantially spherical configuration being substantially hollow for occluding at least a portion of said vesicle, said substantially spherical configuration having about 90% of said strand in about the outer 15% of the diameter of said substantially spherical configuration.
Claim 4
Dependent Claim
78 words
An occlusive device comprising at least one strand of a flexible materal movable between an inoperable substantially linear configuration for insertion into and through a means for delivering the device to a desired portion of a vesicle, and an operable substantially spherical configuration being substantially hollow for occluding at least a portion of said vesicle, said substantially spherical configuration having about 90% of said strand in about the outer 15% of the diameter of said substantially spherical configuration.
