Abstract

Disclosed are stent holding devices having a support mandrel and one or more stent retaining fixtures disposed on the mandrel. The retaining fixture may include a character identifier to facilitate tracking a stent mounted on the holding device. The retaining fixture may include a conical protrusion and a conical recess to allow any number of retaining fixtures to engage each other and be stacked on the mandrel. The retaining fixture may include a tubular member having a spiral cut that enables the diameter of the tubular member to be adjusted to allow for a frictional fit on the mandrel. The retaining fixture may have a Z-shaped or T-shaped structure configured to retain a stent. The stent retaining fixture may also have a filament for retaining a stent.

First claim

What is claimed is:

1. A stent holding device comprising:
a support mandrel sized to fit in a stent lumen of a stent; and
a plurality of fixtures, each fixture configured to be selectively mounted on and removed from the support mandrel, each fixture including a forward facing surface and a rearward facing surface, the forward facing surface having a protruding conical surface that is sloped relative to a longitudinal axis of the support mandrel to allow the protruding conical surface, when exposed, to support an edge of the stent while the support mandrel extends through the stent lumen, the rearward facing surface having an aperture having a conical recess that is configured to receive the protruding conical surface of another one of the plurality of fixtures.

2. The stent holding device of claim 1 , wherein the support mandrel extends into and frictionally engages the aperture of each of the plurality of fixtures.

3. The stent holding device of claim 1 , wherein at least one of the plurality of stent retaining fixtures includes a character identifier, barcode, machine readable graphic, or RFID device.

4. The stent holding device of claim 1 , further comprising a luer attached to one end of the support mandrel.

5. The stent holding device of claim 1 , wherein a first fixture and a second fixture of the plurality of fixtures are arranged on the support mandrel such that the protruding conical surface of the second fixture extends into the conical recess of the first fixture, and the protruding conical surface of the first fixture is exposed to allow the protruding conical surface of the first fixture to support the edge of the stent while the support mandrel extends through the stent lumen.

6. The stent holding device of claim 5 , wherein the first fixture is movable relative to the second fixture while the first and second fixtures are both on the support mandrel such that the first fixture can be selectively separated from the second fixture and brought closer to the second fixture to allow the first and second fixtures to engage each other.

7. The stent holding device of claim 5 , wherein the first and second fixtures are stacked together on the support mandrel such the first fixture keeps the stent from contacting the second fixture.

8. The stent holding device of claim 5 , wherein the protruding conical surface of the second fixture and the conical recess of the first fixture have corresponding shapes that allow the first fixture to engage the second fixture.

9. The stent holding device of claim 5 , wherein a third fixture of the plurality of fixtures is arranged on the support mandrel such that the protruding conical surface of the third fixture extends into the conical recess of the second fixture, and the second fixture is disposed between the first and third fixtures.

10. The stent holding device of claim 9 , wherein the first, second, and third fixtures are stacked together such the first fixture keeps the stent from contacting the second and third fixtures.

11. The stent holding device of claim 9 , wherein the second fixture is movable relative to the third fixture while the second and third fixtures are both on the support mandrel, and the second fixture can be selectively separated from the third fixture and brought closer to the third fixture to allow the second and third fixtures to engage each other.

12. The stent holding device of claim 9 , wherein when the third fixture is on the support mandrel, the first and second fixtures are capable of being removed from the support mandrel to expose the protruding conical surface of the third fixture to allow the exposed protruding conical surface of the third fixture to support the edge of the stent while the support mandrel extends through the stent lumen.

13. The stent holding device of claim 5 , wherein when the second fixture is on the support mandrel, the first fixture is capable of being removed from the support mandrel to expose the protruding conical surface of the second fixture to allow the exposed protruding conical surface of the second fixture to support the edge of the stent while the support mandrel extends through the stent lumen.

14. The stent holding device of claim 1 , wherein each fixture, when mounted on the support mandrel, is movable relative to an adjacent one of the fixtures on the support mandrel and in a direction along the longitudinal axis of the support mandrel.

15. The stent holding device of claim 1 , wherein the support mandrel has a first end segment and a second end segment, the plurality of fixtures are arranged on the first end segment, and the protruding conical surface of the fixture nearest the second end segment of the support mandrel is exposed to allow the exposed protruding conical surface to support the edge of the stent while the support mandrel extends through the stent lumen.

16. The stent holding device of claim 15 , wherein the fixture nearest the second end segment of the support mandrel keeps the stent separated and out of contact from the other fixtures of the plurality of fixtures.

17. The stent holding device of claim 1 , wherein an exterior width of each fixture, as measured in a direction perpendicular to the longitudinal axis of the support mandrel, is the same as that of an adjacent one of the fixtures on the support mandrel.

18. The stent holding device of claim 1 , wherein when the plurality of fixtures are stacked together on the fixture with all forward facing surfaces facing in the same direction, only one of the fixtures is capable of making contact with the stent while the support mandrel extends through the stent lumen.
