1. An implant for occluding a target area of a patient'"'"'s vasculature, comprising:
- a frame comprising a lattice formed of a first plurality of braided filaments that define a first plurality of openings, the first openings having a pore size of from about 1 μ
m to about 400 μ
m, the frame comprising a distal region and a proximal region, the frame being expandable from a compressed configuration to an expanded configuration in which the frame has a generally spherical shape, and wherein the first plurality of filaments are coupled together at a hub disposed at a proximal end of the frame;
a first mesh component coupled to the frame along at least a first portion of the proximal region, the first mesh component comprising a second plurality of braided filaments that define a second plurality of openings, the second pluralities of filaments and openings collectively defining a mesh porosity permitting blood flow therethrough, the mesh porosity being less than a porosity of the frame, such that blood flow into the implant is more restricted along the proximal region than along the distal region of the frame; and
a second mesh component coupled to the frame along at least a second portion of the proximal region, the second portion differing from the first portion, the second mesh component comprising a third plurality of braided filaments that define a third plurality of openings,wherein a proximal end of the implant is configured to be detachably coupled to a delivery device.

Abstract
An implant can include a frame and a mesh component coupled to the frame. The mesh component can define a first porosity, and the frame can define a frame porosity. The combined porosity of the mesh component and the frame can restrict blood flow into the implant.

13. An implant for occluding a target area of a patient'"'"'s vasculature, comprising:
-
a lattice formed of a braided frame comprising first filaments that intersect each other to define first openings having a pore size of from about 1 μ
m to about 400 μ
m, the frame being expandable from a compressed configuration to an expanded configuration in which the frame has a generally spherical shape, wherein the first filaments are coupled together at a hub disposed at a proximal end of the frame,a first mesh component coupled to the frame, the first mesh component comprising second filaments and second openings that collectively define a mesh porosity permitting blood flow therethrough, wherein the mesh porosity is less than a porosity of the frame for restricting blood flow into the implant; and a second mesh component coupled to the frame, the second mesh component comprising a third plurality of braided filaments that define a third plurality of openings, wherein an individual one of the first filaments is between the first and second mesh components, and wherein a proximal end of the implant is configured to be detachably coupled to a delivery device. - View Dependent Claims (14, 15, 16, 17, 18, 19)
