Anatomically shaped vasoocclusive device and method for deploying same
First Claim
1. A 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 for occluding at least a portion of said vesicle, said substantially spherical configuration assuming a substantially minimal energy configuration for said strand.

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 occlusive devices.

- 17. A vesicle-occlusion device for repairing a vessel having a vesicle to restore physiologically normal flow to the vessel, the device comprising at least one strand of a flexible material having a substantially linear configuration that winds into a substantially spherical configuration for occluding at least a portion of the vesicle, said substantially spherical configuration assuming a substantially minimal energy configuration for said strand.
- 19. A vesicle-occlusion device for repairing a vessel having a vesicle to restore physiologically normal flow to the vessel, the device comprising at least one strand of a flexible material having a substantially linear configuration that winds into a three-dimensional configuration approximating the shape of the vesicle into which the device is inserted to occluding at least a portion of the vesicle, said three-dimensional configuration assuming a substantially minimal energy configuration for said strand.
- 22. A vesicle-occlusion device for repairing a vessel having a vesicle to restore physiologically normal flow to the vessel, the device comprising at least one strand of a flexible material having a substantially linear configuration that winds into a three-dimensional cage within the vesicle for occluding at least a portion of the vesicle, said three-dimensional cage assuming a substantially minimal energy configuration for said strand.
- 26. A 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 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.
- 42. A vesicle-occlusion device for repairing a vessel having a vesicle to restore physiologically normal flow to the vessel, the device comprising at least one strand of a flexible material having a substantially linear configuration that winds into a substantially spherical configuration for occluding at least a portion of the vesicle, said substantially spherical configuration having about 90% of said strand in about the outer 15% of the diameter of said substantially spherical configuration.
- 44. A vesicle-occlusion device for repairing a vessel having a vesicle to restore physiologically normal flow to the vessel, the device comprising at least one strand of a flexible material having a substantially linear configuration that winds into a three-dimensional configuration approximating the shape of the vesicle into which the device is inserted to occlude at least a portion of the vesicle, said three-dimensional configuration having about 90% of said strand in about the outer 15% of the diameter of said three-dimensional configuration.
-
48. A method for repairing a vessel having a vesicle to restore physiologically normal flow to the vessel, comprising the steps of:
-
moving a catheter through the vessel and to the vesicle; moving through said catheter a vesicle-occlusion device comprising at least one strand of a flexible material movable between an inoperable substantially linear configuration for insertion into and through said catheter, and an operable, substantially spherical configuration for occluding at least a portion of said vesicle; and delivering said device from said catheter and into the vesicle to form said substantially spherical configuration for occluding at least a portion of the vesicle, said substantially spherical configuration assuming a substantially minimal energy configuration for said strand.
