Abstract

An occlusive implant system may include a catheter having a lumen extending therethrough, a core wire slidably and rotatably disposed within the lumen, the core wire having a threaded member disposed at a distal end, and a medical implant having an expandable frame, an occlusive element disposed on the frame, and a threaded insert coupled to a proximal portion of the frame, wherein the threaded member is removably coupled to the threaded insert.

First claim

What is claimed is:

1. A medical implant, comprising:
a frame configured to actuate between a collapsed configuration and an expanded configuration; and
an occlusive element covering at least a portion of the frame;
wherein a proximal end of the frame forms a generally tubular portion, the tubular portion being configured to attach to a distal end of a core wire;
wherein the tubular portion of the frame includes a threaded insert coupled thereto.

2. The implant of claim 1 , wherein the frame includes an annular collar member at least partially disposed within the tubular portion and coupled thereto, the threaded insert being coupled to the annular collar member.

3. The implant of claim 2 , wherein the threaded insert is disposed within the annular collar member.

4. The implant of claim 3 , wherein a portion of the occlusive element is disposed between the threaded insert and the annular collar member.

5. The implant of claim 4 , wherein the threaded insert is disposed distally of a portion of the occlusive element disposed outside of the annular collar member.

6. The implant of claim 4 , wherein an outer portion of the occlusive element is defined as that part of the occlusive element disposed outside of the annular collar member, wherein the outer portion of the occlusive element is disposed radially outward from the threaded insert in the expanded configuration.

7. The implant of claim 2 , further including a pin element coupling the annular collar member to the frame.

8. The implant of claim 1 , wherein the frame includes a plurality of proximally-facing hooks disposed about a periphery of the frame in the expanded configuration.

9. The implant of claim 1 , wherein the distal end of the core wire includes a threaded member configured to mate with the threaded insert.
