Abstract

A medical system for treating an internal tissue opening can include a closure device and associated delivery device. The delivery device can include an actuating assembly configured to partially deploy the closure device by a first movement, and deploy a second portion of the closure device by a second movement. The delivery device can also include a release assembly to selectively release or disconnect the closure device from the delivery device. The delivery device can include a tip member coupled to the distal end of a catheter. The tip member can include a first passageway and a second passageway being in a spaced apart arrangement. A guidewire can be received into the first passageway to facilitate positioning of the delivery device. The second passageway can house and facilitate delivery of the closure device.

Claims

1. A medical implant delivery system for delivering a medical device in a human body, the delivery system comprising:

a handle;

a catheter coupled to the handle with lines coupled to the medical device; and

a tip portion coupled to a distal end of the catheter, the tip portion defining at least a first passageway and a second passageway extending at least partially along a length through the tip portion, the first passageway configured to move over a guide wire and the second passageway configured to communicate with the catheter and configured to facilitate delivery of the medical device, the first passageway and the second passageway being in a spaced apart arrangement.

2. A medical system as recited in claim 1, wherein said first passageway includes a first opening and a second opening in communication with said first opening, wherein said first and second openings are positioned in said tip portion.

3. A medical system as recited in claim 1, wherein said first passageway defines a first lumen.

4. A medical system as recited in claim 3, wherein said second passageway defines a second lumen, wherein said first lumen is separate and distinct from said second lumen.

5. A medical system as recited in claim 1, wherein said second passageway is configured to enable the medical device to be received therein and deployed therefrom.

6. A medical system as recited in claim 1, wherein at least a portion of said lines extend at least partially through said second passageway.

7. A delivery device configured to be coupled to a catheter for delivering a medical device in a human body, the delivery device comprising:

a tip member configured to be coupled at a distal end of the catheter, the tip member defining at least a first passageway and a second passageway extending at least partially along a length through the tip member, the first passageway configured to move over a guide wire and the second passageway configured to communicate with the catheter and configured to facilitate delivery of the medical device, the first passageway and the second passageway being in a spaced apart arrangement.

8. A delivery device as recited in claim 7, further comprising a delivery assembly operably associated with said tip member to facilitate deployment of the medical device from said second passageway.

9. A delivery device as recited in claim 7, wherein said first passageway includes an inlet and an outlet in communication with said inlet.

10. A delivery device as recited in claim 9, wherein said inlet is positioned at a distal portion of the delivery device.

11. A delivery device as recited in claim 9, wherein said inlet and said outlet are positioned at a distal portion of the delivery device.

12. A delivery device as recited in claim 7, wherein said tip member defines said first passageway.

13. A delivery device as recited in claim 7, wherein said tip member comprises a distal end and a proximal end, wherein said second passageway extends from said distal end to said proximal end.

14. A medical implant delivery system for delivering a medical device in a human body, the delivery system comprising:

a handle;

a catheter coupled to the handle with lines coupled to the medical device; and

a tip portion coupled to a distal end of the catheter, the tip portion defining at least a first passageway and a second passageway extending at least partially along a length through the tip portion, the first passageway configured to move over a guide wire and the second passageway configured to communicate with the catheter and configured to deliver the medical device, the second passageway and the first passageway being in a non-coaxial arrangement.

15. A delivery system as recited in claim 14, further comprising an actuating assembly configured to facilitate delivery of the medical device.

16. A delivery system as recited in claim 14, wherein said first passageway is configured such that the guide wire can be received into and extended from said first passageway at a distal end of the delivery system.

17. A delivery system as recited in claim 14, wherein said first passageway includes an inlet and an outlet in communication with said inlet.

18. A delivery device as recited in claim 17, wherein said inlet is positioned at a distal portion of the delivery system.

19. A delivery system as recited in claim 14, wherein said first passageway defines a first lumen.

20. A delivery system as recited in claim 19, wherein said second passageway defines a second lumen, wherein said first lumen is separate and distinct from said second lumen.
