Abstract
A stent loading device is configured to perform a method of loading a stent into a delivery tube that comprises loading a stent into an opening of a crimping device. The stent has an initial uncompressed diameter. The method further comprises crimping the stent via the crimping device in a manner reducing the diameter of the stent from the initial diameter. Still further, the method comprises forcing the stent out of the opening of the crimping device and into a passageway of a delivery tube while oscillating the crimping device. The passageway of the delivery tube has a diameter that is less than the initial diameter of the stent and receives the stent in its compressed state.
Claims8
A method of loading a stent into a delivery tube, the method comprising:
- loading a stent into an opening of a crimping device of a stent loading device, the stent having an initial diameter, the opening having an adjustable size, the stent loading device comprising a control system and a motor driven threaded member that is functionally connected to the crimping device in a manner such that rotation of the motor driven threaded member controllably adjusts the size of the opening of the crimping device;
- crimping the stent via the crimping device in a manner reducing the diameter of the stent from the initial diameter;
- and
- forcing the stent out of the opening of the crimping device and into a passageway of a delivery tube while oscillating the size of the opening of the crimping device, and thereby oscillating the stent, by rapidly changing rotational direction of the motor driven threaded member, the control system limiting the amplitude of the oscillations of the size of the opening of the crimping device by limiting the amount the threaded member rotates during the oscillations, the passageway of the delivery tube having a diameter that is less than the initial diameter of the stent.
