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:

covering an aperture in a sidewall of a catheter with a cover member;

positioning a support member over the cover member;

inserting an end portion of the support member into the aperture to engage the end portion with the catheter, thereby coupling the cover member to the catheter; and

everting an end section of the cover member over the end portion of the support member.

2. The method of claim 1, wherein the inserting comprises urging a portion of the cover member into the aperture.

3. The method of claim 1, further comprising closing an end of the end section.

4. The method of claim 1, wherein the inserting comprises engaging an elongate member, extending within a lumen of the catheter, with the support member end portion.

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

6. The method of claim 5, wherein the piercing the cover member comprises piercing cover member with the elongate member to engage the elongate member with the support member end portion.

7. The method of claim 1, wherein the support member comprises a self-expanding frame, and the positioning comprises compressing the support member onto the catheter.

8. The method of claim 1, wherein the support member comprises a helical coil.

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

positioning a cover member over an aperture in a sidewall of a catheter;

urging an end portion of a support member into the aperture to engage the end portion with the catheter, thereby coupling the cover member to the catheter;

closing an end of the cover member; and

engaging an elongate member, extending within a lumen of the catheter, with the support member end portion.

10. The method of claim 9, wherein the support member comprises a self-expanding frame.

11. The method of claim 9, wherein the support member comprises a helical coil.

12. The method of claim 9, further comprising everting an end section of the cover member over the support member.

13. The method of claim 12, further comprising, after everting the end section of the cover member, coupling the end section of the cover member with a second end section of the cover member to close a distal end of the occlusive device.

14. The method of claim 9, further comprising piercing the cover member to engage the elongate member with the support member end portion.

15. The method of claim 14, wherein the piercing the cover member comprises piercing cover member with the elongate member to engage the elongate member with the support member end portion.

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

covering a first engagement section of a catheter with a cover member;

positioning a support member over the cover member;

restraining an end portion of the support member at the first engagement section to engage the end portion with the catheter, thereby coupling the cover member to the catheter;

closing an end of the cover member; and

engaging an elongate member, extending within a lumen of the catheter, with the end portion.

17. The method of claim 16, wherein the first engagement section of the catheter comprises an aperture, and wherein the restraining comprises inserting the end portion into the aperture.

18. The method of claim 16, further comprising everting an end section of the cover member over the end portion.

19. The method of claim 16, further comprising piercing the cover member to engage the elongate member with the end portion.

20. The method of claim 16, wherein the support member comprises a helical coil.

21. The method of claim 16, wherein the support member is self-expanding.
