Abstract
A medical implant, having a proximal and a distal end, that is preformed to assume a superimposed structure at an implantation site but can be made to take on a volume-reduced form making it possible to introduce it by means of a micro-catheter and a guide wire arranged at the proximal end, with the implant in its superimposed structure assuming the form of a longitudinally open tube and having a mesh structure of interconnected strings or filaments. The implant has a tapering structure at its proximal end where the strings or filaments converge at a connection point.

17. An implant, comprising:
-
a first mesh portion comprising a first plurality of mesh cells of a first mesh cell size, the first mesh portion having a distal and a proximal end; a second mesh portion comprising a second plurality of mesh cells of a second mesh cell size, the second mesh portion having a distal and a proximal end, the second mesh portion coupled to the proximal end of the first mesh portion; and a single connection point at which the proximal end of the second mesh portion terminates. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

32. A method, comprising:
-
providing an implant having a first mesh portion comprising a first plurality of mesh cells of a first mesh cell size, the first mesh portion having a distal and a proximal end, a second mesh portion comprising a second plurality of mesh cells of a second mesh cell size, the second mesh portion having a distal and a proximal end, the second mesh portion coupled to the proximal end of the first mesh portion, and a single connection point at which the proximal end of the second mesh portion terminates; preforming the implant to have a first preformed shape; curling the implant into a longitudinally-shaped open tube configuration tapering toward the connection point; maintaining the implant, via a mechanical restraint, in the open tube configuration; placing the implant in a vessel of a patient; removing the mechanical restraint; and leaving the implant positioned in the vessel. - View Dependent Claims (33, 34)
