Abstract

An occlusion system can include an expandable implant that can be delivered to a bodily lumen. The implant can be carried on an engagement section of a catheter used in the system. The implant can be assembled onto the catheter by coupling a cover member of the implant with a support member of the implant. When assembled, the system can be advantageously configured to have a low delivery profile to facilitate delivery through catheters having a size of less than 7 Fr, and in some cases, less than 6 Fr.

Claims

1. A method for manufacturing an occlusive device, the method comprising:

positioning a first end section of a cover member over an aperture in an engagement section of a catheter;

positioning a support member over the engagement section, thereby covering the first end section;

inserting an end portion of the support member into the aperture;

everting a second end section of the cover member over the first end section; and

closing an end of the second end section.

2. The method of claim 1, wherein the support member is self-expanding, and the positioning the support member comprises compressing the support member onto the engagement section.

3. The method of claim 1, wherein the inserting comprises engaging an elongate member with the support member end portion in the aperture.

4. The method of claim 3, further comprising piercing the cover member to engage the elongate member with the support member end portion in the aperture.

5. The method of claim 3, wherein the engaging comprises positioning the elongate member within the aperture, radially between of the support member end portion and a wall of the catheter.

6. The method of claim 1, wherein the aperture is a first aperture and the support member end portion is a support member first end portion, and the method further comprises inserting a second end portion of the support member into a second aperture of the catheter, the second aperture being distal to the first aperture.

7. The method of claim 6, wherein the elongate member is a first elongate member, and the inserting the support member second end portion comprises engaging a second elongate member with the support member second end portion in the second aperture.

8. The method of claim 6, wherein the inserting the second end portion comprises engaging the elongate member with the support member second end portion in the second aperture.

9. The method of claim 1, wherein the closing the end of the second end section comprises suturing, clipping, or gluing the end.

10. The method of claim 1, wherein the positioning the first end section comprises positioning an end of the first end section longitudinally between the aperture and a distal end of the catheter.

11. The method of claim 1, wherein the positioning the first end section comprises positioning an end of the first end section longitudinally distal to a distal end of the catheter.

12. The method of claim 11, wherein the closing comprises coupling the first end section to the second end section.

13. The method of claim 11, wherein the first section comprises a plurality of strips.
