Abstract
An occlusive device for occluding a target area can include an elongate member having opposing first and second side edges extending longitudinally along the member and a member width. The member can have a collapsed configuration in which the first and second side edges are curled toward each other about a longitudinal axis of the member. Further the member can have an expanded configuration in which the member form a series of loops and the first and second side edges uncurl to be spaced apart from each other.
Claims18
A method of operating an occlusive device assembly, comprising:
- advancing an elongate member in a collapsed configuration within a catheter, the member formed of a continuous sheet of material and having opposing first and second side edges extending along a longitudinal axis of the member, wherein the first and second side edges, in the collapsed configuration, are rolled or curled about a line at least substantially parallel to the longitudinal axis of the member;
- and
- urging a distal end of the member beyond a distal end of the catheter toward an aneurysm, thereby causing the member to unfurl to an expanded configuration in which the first and second side edges move away from each other.
A method for occluding an aneurysm, comprising:
- providing an elongate member formed of a continuous sheet of material, the member including (i) opposing edges extending longitudinally along the member and (ii) a body extending between the opposing edges;
- advancing the member in a collapsed configuration within a catheter toward an aneurysm, wherein, in the collapsed configuration, the member is curled or rolled within the catheter such that a first portion of the body is radially inward of a second portion of the body;
- and
- urging a distal end of the member beyond a distal end of the catheter toward the aneurysm, thereby causing the member to unfurl to an expanded configuration in which the opposing side edges are urged away from one another.
A method for implanting an occlusive device within a patient, comprising:
- providing an elongate member formed of a continuous sheet of material, the member including opposing edges extending longitudinally along the member;
- advancing the member in a collapsed configuration within a catheter, wherein, in the collapsed configuration, the member is curled or rolled within the catheter such that a first portion of the member is radially inward of a second portion of the member;
- and
- releasing the member from the catheter, thereby causing the member to unfurl to an expanded configuration in which the opposing side edges are urged away from one another and the member forms a substantially spherical shape;
- and
- after releasing the member, withdrawing the catheter from the patient.
