Abstract

A device for crimping an collapsible device and loading the collapsible device into a delivery system, includes a crimping tool configured to radially crimp at least a portion of the collapsible device, a loading tool configured to load at least a portion of the collapsible device into a delivery system, and a housing that houses at least one of the crimping tool and loading tool, wherein the device is configured to crimp and load the collapsible device without requiring manual repositioning of the collapsible device. Methods of crimping an collapsible device and loading the collapsible device into a delivery system are also disclosed.

Claims

1. A device for crimping and loading a collapsible device into a delivery system, the device comprising:

a crimping tool configured to radially crimp at least a portion of the collapsible device;

a loading tool configured to load at least a portion of the collapsible device into a delivery system; and

a housing that houses at least one of the crimping tool and loading tool,

wherein the device is configured to crimp and load the collapsible device without requiring manual repositioning of the collapsible device.

2. The device of claim 1, further comprising:

an actuator configured to actuate the crimping tool to radially crimp at least a portion of the collapsible device when the actuator is moved a predetermined amount relative to the housing.

3. The device of claim 2, wherein the actuator is configured to actuate the crimping tool to radially crimp at least a portion of the collapsible device when the actuator is moved a predetermined amount in the axial direction relative to the housing.

4. The device of claim 2, wherein the actuator is configured to actuate the crimping tool to radially crimp at least a portion of the collapsible device when the actuator is rotated a predetermined amount relative to the housing.

5. The device of claim 1, further comprising:

an actuator configured to actuate the loading tool to load at least a portion of the collapsible device into the delivery system when the actuator is moved a predetermined amount relative to the housing.

6. The device of claim 5, wherein the actuator is configured to actuate the loading tool to load at least a portion of the collapsible device into the delivery system when the actuator is moved a predetermined amount in an axial direction relative to the housing.

7. The device of claim 1, further comprising:

an actuator configured to actuate the crimping tool to radially crimp at least a portion of the collapsible device when the actuator is moved from a first predetermined position relative to the housing to a second predetermined position relative to the housing,

wherein the actuator is configured to actuate the loading tool to load at least a portion of the collapsible device into the delivery system when the actuator is moved from the second predetermined position relative to the housing to a third predetermined position relative to the housing.

8. The device of claim 1, further comprising:

an actuator configured to actuate the crimping tool to radially crimp at least a portion of the collapsible device when the actuator is moved from a first predetermined position relative to the housing to a second predetermined position relative to the housing,

wherein the actuator is configured to actuate the loading tool to load at least a portion of the collapsible device into the delivery system when the actuator is moved from a third predetermined position relative to the housing to a fourth predetermined position relative to the housing.

9. The device of claim 1, further comprising:

an actuator configured to actuate the crimping tool to radially crimp at least a portion of the collapsible device when the actuator is moved in a first axial direction from a first predetermined position relative to the housing to a second predetermined position relative to the housing,

wherein the actuator is configured to actuate the loading tool to load at least a portion of the collapsible device into the delivery system when the actuator is moved in a second and opposite axial direction from a third predetermined position relative to the housing to a fourth predetermined position relative to the housing.

10. The device of claim 9, wherein the second predetermined position is the same as the third predetermined position.

11. The device of claim 1, further comprising:

an actuator configured to actuate the crimping tool to radially crimp at least a portion of the collapsible device when the actuator is moved in a rotational direction from a first predetermined position relative to the housing to a second predetermined position relative to the housing,

wherein the actuator is configured to actuate the loading tool to load at least a portion of the collapsible device into the delivery system when the actuator is moved in an axial direction from a third predetermined position relative to the housing to a fourth predetermined position relative to the housing.

12. The device of claim 11, wherein the second predetermined position is the same as the third predetermined position.

13. The device of claim 1, further comprising:

an actuator configured to actuate the crimping tool to radially crimp at least a portion of the collapsible device when the actuator is rotated from a first predetermined position relative to the housing to a second predetermined position relative to the housing,

wherein the actuator is configured to actuate the loading tool to load at least a portion of the collapsible device into the delivery system when the actuator is moved front a third predetermined position relative to the housing to a fourth predetermined position relative to the housing.

14. The device of claim 1, wherein the second predetermined position is the same as the third predetermined position.

15. A method of crimping and loading a collapsible device into a delivery system, the method comprising:

obtaining a crimping and loading device comprising;

a crimping tool configured to radially crimp at least a portion of the collapsible device;

a loading tool configured to load at least a portion of the collapsible device into a delivery system; and

a housing that houses at least one of the crimping tool and loading tool,

wherein the device is configured to crimp and load the collapsible device without requiring manual repositioning of the collapsible device,

wherein the crimping tool includes an actuator configured to actuate the crimping tool to radially crimp at least a portion of the collapsible device when the actuator is moved a predetermined amount relative to the housing, and

wherein the crimping tool includes an actuator configured to actuate the loading tool to load at least a portion of the collapsible device into the delivery system when the actuator is moved a predetermined amount relative to the housing; and

moving the actuator a predetermined amount relative to the housing to crimp the collapsible device.

16. The method of claim 15, wherein the act of moving the actuator a predetermined amount relative to the housing to crimp the collapsible device includes rotating the actuator a predetermined amount relative to the housing.

17. The method of claim 15, wherein the act of moving the actuator a predetermined amount relative to the housing to crimp the collapsible device includes moving the actuator a predetermined amount in the axial direction relative to the housing.

18. The method of claim 15, further comprising:

moving the actuator a predetermined amount relative to the housing to load the collapsible device.

19. The method of claim 18, wherein the act of loading the collapsible device includes loading the collapsible device into a catheter.

20. The method of claim 18, wherein the act of moving the actuator a predetermined amount relative to the housing to load the collapsible device includes moving the actuator a predetermined amount in an axial direction relative to the housing.
