1. A vasoocclusive device that is adapted to be inserted into a portion of a vasculature for occluding a portion of the vasculature for use in interventional therapy and vascular surgery, comprising:
- at least one strand of a flexible material formed to have a first inoperable, substantially linear configuration for insertion into and through a catheter to a desired portion of the vasculature to be treated, and a second operable configuration for framing or occluding the desired part of the vasculature to be treated, said operable configuration including a first portion configured to frame or occlude a part of the vasculature to be treated and a second non linear portion configured to engage an artery wall for securing the occluding device in the artery system of the vasculature.

Abstract
This invention relates generally to vasoocclusive devices, and more particularly concerns a vasoocclusive device that has a first elongated, reduced friction configuration in which the vasoocclusive device may be deployed through a catheter or cannula to an anatomical cavity at a site in the vasculature to be treated. The device has a second configuration assumed at the site to be treated which consists of a component that creates an anchor in the adjacent vasculature and a component for framing or filling the anatomical cavity.

17. A vasoocclusive device that is adapted to be inserted into a portion of a vasculature for occluding a portion of the vasculature for use in interventional therapy and vascular surgery, comprising:
-
at least one strand of a flexible material formed to have a first inoperable, substantially linear configuration for insertion into and through a catheter to a desired portion of the vasculature to be treated, and a second operable configuration having an anchor segment loaded into the adjacent artery and a coil segment for framing or occluding the desired part of the vasculature to be treated, said operable configuration including a first portion configured to frame or occlude a part of the vasculature to be treated and a second non-linear portion configured to engage an artery wall for securing the occluding device in the artery system of the vasculature; and
wherein said anchor portion is formed to reinforce the vessel in the vicinity of the damaged portion of the vasculature to be treated. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39)

40. A vasoocclusive device that is adapted to be inserted into a portion of a vasculature for occluding a portion of the vasculature for use in interventional therapy and vascular surgery, comprising:
at least one strand of a flexible material formed to have a first inoperable, substantially linear configuration for insertion into and through a catheter to a desired portion of the vasculature to be treated, and a second operable configuration for framing or occluding the desired site of the vasculature to be treated, said operable configuration including a first portion configured to frame or occlude a part of the vasculature to be treated and a second non-linear portion configured to engage an artery wall for securing the occluding device in the artery system of the vasculature, wherein the operable configuration for framing or occluding the desired site of the vasculature further comprises at least one extending loop to anchor the occluding portion of the device in the artery system of the vasculature. - View Dependent Claims (41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53)

54. A method for repairing a portion of a vasculature having a vasoocclusive deformity to restore physiologically normal flow to the portion of the vasculature to be treated, comprising the steps of:
-
moving a catheter through the vasculature and to the portion of the vasculature to be treated;
moving through said catheter a vasoocclusive device comprising at least one strand of a flexible material formed to have a first inoperable, substantially linear configuration for insertion into and through a catheter to a desired portion of the vasculature to be treated, and a second operable configuration for framing or occluding the desired portion of the vasculature to be treated, and anchoring a portion of said second operable configuration of the device in the artery system of the vasculature. - View Dependent Claims (55)
