Abstract

A stent delivery device has a handle and a sliding body, the sliding body is slidable with respect to the handle. The handle has a grip and a guide. The sliding body has at least two flange portions extending from the sliding body. The flange portions are offset from one another along the length of the sliding body. The operator can thereby deploy a relatively long stent by first gripping the nearest flange portion and pulling the sliding body toward the handle; subsequently, the operator can reposition his/or finger on the next-nearest flange portion and continue deployment of the stent by pulling the sliding body further toward the handle.

Claims

1. A stent delivery device comprising:

a handle having a grip, a guide, and a protruding member, the handle defining a cavity, the protruding member extending into the cavity; and

a sliding body comprising a guide surface and a plurality of flange portions, the flange portions longitudinally offset from one another, wherein the guide surface is slidably engaged to the guide and the sliding body is slidable over the protruding member.

2. The stent delivery device of claim 1 wherein the guide defines a channel and the sliding body comprises a ridge, the ridge having the guide surface thereon.

3. The stent delivery device of claim 1 wherein the guide comprises a ridge and the sliding body defines a channel, the channel further defining a guide surface.

4. The stent delivery device of claim 1, wherein the handle comprises a first guide and a second guide and the sliding body comprises a first ridge and a second ridge, the first ridge slidably engaged to the first guide and the second ridge slidably engaged to the second guide.

5. The stent delivery device of claim 4, wherein the first ridge is opposite the second ridge.

6. The stent delivery device of claim 1, wherein the sliding body defines a cavity and the protruding member is insertable into the cavity.

7. The stent delivery device of claim 1, wherein the protruding member defines a hole extending therethrough.

8. The stent delivery device of claim 1, wherein the sliding body has two flange portions.

9. The stent delivery device of claim 1, wherein the sliding body has four flange portions.

10. The stent delivery device of claim 9, wherein two of the flange portions are longitudinally offset from the other two flange portions.

11. The stent delivery device of claim 1, wherein grip comprises a pistol grip.

12. A delivery device for delivering a medical implant, the delivery device comprising:

a handle and a sliding body, the handle comprising a main body, a grip, and a pair of arms extending from the main body, each of the arms comprising a guide; and

a sliding body comprising a plurality of guide surfaces and a plurality of flange portions, the flange portions being longitudinally offset from one another and the guide surfaces slidably engaging the guides, wherein the sliding body defines a first hole extending therethrough and the handle defines a second hole extending therethrough, the first and second holes having a common longitudinal axis.

13. The delivery device of claim 12, wherein the handle further comprises a protruding member, the second hole extending through the protruding member.

14. The delivery device of claim 13, wherein the sliding body defines a cavity and the protruding member is insertable into the cavity.

15. The delivery device of claim 12 having a first configuration and a second configuration, in the first configuration the sliding body being in a first position and, in the second configuration, the sliding body being in a second position, the second position longitudinally offset from the first position.

16. A delivery device for delivering a medical implant, the delivery device comprising:

a handle defining a cavity and comprising a grip and at least one guide, the at least one guide extending from the handle; and

a sliding body comprising a body portion and a plurality of flange portions, the flange portions extending from the body portion and being longitudinally offset from one another, wherein at least a portion of the sliding body is slidable along the at least one guide between an extended configuration and a retracted configuration.

17. The delivery device of claim 16, wherein the at least one guide comprises two guides arranged in an opposing relationship.

18. The delivery device of claim 17, wherein the handle further comprises a protruding member extending into the cavity between the two guides.

19. The delivery device of claim 18, wherein each of the guides defines a channel and the sliding body comprises two ridges, the ridges slidable along the channels.

20. The delivery device of claim 18, wherein the sliding body is slidable over the protruding member.
