Abstract

A device and method for delivering an object within a patient, wherein the object is delivered in a preferred orientation relative to the delivery site of the patient. The delivery device has an alignment member that allows the object to be delivered intravascularly to the delivery site of the patient, wherein the object is delivered in a pre-determined orientation. The object may, for example, be non-symmetric or include a configuration that requires delivery to the site in only one suitable orientation relative to the delivery site. Such objects may be used, for example, to treat certain defects or injuries in vessels or organs within a patient'"'"'s body.

Claims

1. A delivery device suitable for delivering a collapsible device to a pre-selected region within a patient, said delivery device comprising:

an elongated pusher catheter having a proximal end and a distal end, said distal end includes a distal tip having a radial alignment member adapted for mating with a connecting member of the collapsible device, wherein the radial orientation of the radial alignment member relative to a longitudinal axis of the elongated pusher catheter is predetermined.

2. The delivery device as recited in claim 1, wherein said pusher catheter includes a lumen extending through the elongated pusher catheter between the proximal end and distal end, and wherein said distal tip includes an aperture extending there through and aligned with said lumen.

3. The delivery device as recited in claim 2, further including a cable extending through the lumen of said pusher catheter, wherein a distal end of said cable is extendable through the aperture of the distal tip and coupleable to the collapsible device.

4. The delivery device as recited in claim 3, wherein the distal end of said cable includes a threaded outer surface.

5. The delivery device as recited in claim 1, wherein said radial alignment member has a semicircular shape.

6. The delivery device as recited in claim 1, wherein the radial orientation of the connecting member of the collapsible device relative to a shape of the collapsible device is preset.

7. The delivery device as recited in claim 1, wherein the mating between the radial alignment member and connecting member inhibits the collapsible device from rotating about the distal tip.

16. The delivery device as recited in claim 1, wherein said elongated cylindrical member includes a lumen extending through the elongated cylindrical member between the proximal and distal end, and wherein said distal tip includes an aperture extending there through and aligned with said lumen.

17. The delivery device as recited in claim 16, further including a cable extending through the lumen of said elongated cylindrical member, wherein a distal end of said cable is extendable through the aperture of the distal tip and coupleable to the non-symmetrical collapsible device.

18. The delivery device as recited in claim 17, wherein the distal end of said cable includes a threaded outer surface.

8. A delivery device suitable for delivering a collapsible device to a pre-selected region within a patient, said delivery device comprising:

an elongated pusher catheter having a proximal end and a distal end, said distal end includes a distal tip having means for radially aligning a connecting member of the collapsible device in a predetermined radial orientation relative to the distal tip, said distal tip further including means for mating the distal tip with said connecting member, wherein the predetermined radial orientation relative to the distal tip is further set relative to a bend fixed in the pusher catheter.

9. The delivery device as recited in claim 8, wherein said pusher catheter includes a lumen extending through the elongated pusher catheter between the proximal end and distal end, and wherein said distal tip includes an aperture extending therethrough and aligned with said lumen.

10. The delivery device as recited in claim 9, further including a cable extending through the lumen of said pusher catheter, wherein a distal end of said cable is extendable through the aperture of the distal tip and coupleable to the collapsible device.

11. The delivery device as recited in claim 10, wherein the distal end of said cable includes a threaded outer surface.

12. The delivery device as recited in claim 8, wherein said means for radially aligning includes a semicircular shape.

13. The delivery device as recited in claim 8, wherein the orientation of the connecting member of the collapsible device relative to a shape of the collapsible device is preset.

14. The delivery device as recited in claim 8, wherein mating between the means for radially aligning and the connecting member inhibits the collapsible device from rotating about the distal tip.

15. A delivery device suitable for delivering a non-symmetrical collapsible device to a pre-selected region within a patient, said delivery device comprising:

a flexible, elongated cylindrical member having a proximal end and a distal end, said distal end of said elongated cylindrical member includes a distal tip having a radial alignment member adapted for mating with a connecting member of the non-symmetrical collapsible device, wherein the radial alignment member includes a means for radially aligning a first point on the non-symmetrical collapsible device with a second point on the elongated cylindrical member.

19. The delivery device as recited in claim 15, further wherein the radial orientation of the connecting member of the non-symmetrical collapsible device relative to a shape of the non-symmetrical collapsible device is preset.

20. The delivery device as recited in claim 15, wherein the mating between the radial alignment member and connecting member inhibits the non-symmetrical collapsible device from rotating about the distal tip.
