Abstract

A stent container has a first wall at the proximal end and a second wall at the distal end. The first wall has an opening therethrough sized for receiving an uncrimped stent therethrough. The opening opens into a chamber which is reducible in size from a first enlarged size to a second reduced size. The chamber in the first enlarged size is sized for receiving an uncrimped stent therein. A plurality of bars extend from the first wall to the second wall. The bars are movable between a first position and a second position. The plurality of bars in the first position and the first and second walls define the periphery of the chamber in the enlarged size. The plurality of bars in the second position and the first and second walls define the periphery of the chamber in the reduced size. A stent disposed in the chamber may be reduced in size by reducing the chamber from the first enlarged size to the second reduced size.

Claims

1. A stent container having a proximal end and a distal end comprising:

a first wall at the proximal end and a second wall at the distal end, the first wall having a center with a plurality of slots disposed about the center, each of the slots arcing toward the center, and an opening therethrough sized for receiving an uncrimped stent therethrough and opening into a chamber, the chamber reducible in size from a first enlarged size to a second reduced size, the chamber in the first enlarged size sized for receiving an uncrimped stent therein;

a plurality of bars movably received in the slots, said bars extending from the first wall to the second wall, the bars movable between a first position and a second position, the plurality of bars in the first position and the first and second walls defining the periphery of the chamber in the enlarged size,

the plurality of bars in the second position and the first and second walls defining the periphery of the chamber in the reduced size.

2. The stent container of claim 1 wherein the second wall has a plurality of radially disposed grooves therein, the bars movably received in the grooves.

3. The stent container of claim 2 further comprising a centering pin therein.

4. The stent container of claim 2 wherein the first wall is rotatable relative to the second wall.

5. The stent container of claim 4 further comprising a centering pin disposed within the stent.
