1. A system comprising:
- a self-expanding device configured to be delivered to an anatomical location;
a crimping device for crimping the self-expanding device having an unexpanded configuration and an expanded configuration;
and an applicator or storage member,wherein the crimping device comprises a crimping member, wherein the crimping member engages the self-expanding device to reduce the self-expanding device to its unexpanded configuration, and wherein the crimping device engages the applicator or storage member to hold the self-expanding device in its unexpanded configuration.

Abstract
Described here are devices and methods for crimping self-expanding devices. The crimping devices may be useful for crimping a variety of different self-expanding devices (whether such devices are biodegradable or bio-durable). The crimping devices may have crimping members to engage the self-expanding device to reduce the device from an expanding configuration to an unexpanded configuration. The crimping member may comprise or include a suture, wire, ribbon, guiding hoop, pusher, prong, holding bar, balloon, jaws, combinations thereof, or the like. The crimping devices may also include or comprise a holding structure to hold the self-expanding device in an unexpanded or expanded configuration.

1. A system comprising:
-
a self-expanding device configured to be delivered to an anatomical location; a crimping device for crimping the self-expanding device having an unexpanded configuration and an expanded configuration; and an applicator or storage member, wherein the crimping device comprises a crimping member, wherein the crimping member engages the self-expanding device to reduce the self-expanding device to its unexpanded configuration, and wherein the crimping device engages the applicator or storage member to hold the self-expanding device in its unexpanded configuration. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A crimping device for crimping a self-expanding device having an unexpanded configuration and an expanded configuration, the crimping device comprising:
-
a holding structure, the holding structure comprising a hoop configured to hold therein the self-expanding device in its expanded configuration, the hoop comprising slots; and a crimping member positioned in the holding structure, wherein ends of the crimping member extend through respective slots, wherein movement of the ends of the crimping member through the slots reduces the amount of crimping member in the holding structure and causes the crimping device to reduce the self-expanding device to its unexpanded configuration. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28)

29. A crimping device for crimping a self-expanding device having an unexpanded configuration and an expanded configuration, the crimping device comprising:
-
a crimping portion, the crimping portion having a first end, a second end, an interior surface and a plurality of slits running between the first and second ends, wherein the cross-sectional area of the crimping portion decreases from the second end to the first end, and wherein the interior surface of the crimping portion is configured to house the self-expanding device in its expanded configuration; and a pusher, wherein the pusher includes a plurality of prongs that engage one or more of the plurality of slits and wherein movement of the pusher from the second end of the crimping portion to the first end of the frame compresses the self-expanding device into its unexpanded configuration. - View Dependent Claims (30, 31, 32, 33, 34)

35. A crimping device for holding a crimped self-expanding device having an unexpanded configuration and an expanded configuration, the crimping device comprising:
-
a crimping portion, the crimping portion configured to reduce the self-expanding device to its unexpanded configuration; a storage zone, the storage zone configured to house the self-expanding device in its unexpanded configuration; and an applicator engagement portion, the applicator engagement portion configured to engage a distal end of an applicator. - View Dependent Claims (36, 37, 38, 39)
