Abstract

Devices, methods, and systems are provided for loading an implantable device into a container. One aspect of the loading system contains a loader element with a loading tunnel that is configured to gradually contract an implantable device into a compressed state of reduced size relative to an expanded state as the implantable device travels through the loading tunnel.

First claim

What is claimed is:

1. A method for loading an implantable device into a container, comprising:
pulling an implantable device using a puller element through a loading tunnel in a loading element thereby contracting the implantable device into a compressed state of reduced size relative to an expanded state as the implantable device travels through the loading tunnel, wherein the puller element is removably attached to the implantable device via a suture; and
automatically releasing the suture after the implantable device is contracted into the compressed state;
wherein a rotator disposed on the puller element is removably attached to the suture; and
wherein automatically releasing the suture after the implantable device is contracted into the compressed state comprises rotation of the rotator thereby causing the suture to detach from the rotator.

2. The method of claim 1 , wherein the suture is drawn through and exits the implantable device after the detachment of the suture from the rotator thereby detaching the suture from the implantable device.

3. The method of claim 1 , further comprising separating the puller element from the loading element.

4. The method of claim 1 , wherein the implantable device is a pulmonary implant.

5. A method for loading an implantable device into a container, comprising:
pulling an implantable device using a puller element through a loading tunnel in a loading element thereby contracting the implantable device into a compressed state of reduced size relative to an expanded state as the implantable device travels through the loading tunnel, wherein the puller element is removably attached to the implantable device via a suture;
automatically releasing the suture after the implantable device is contracted into the compressed state;
pushing the implantable device through the loading tunnel and into the delivery catheter using a plunger.

6. The method of claim 5 , further comprising placing a portion of the delivery catheter into the loading element.

7. The method of claim 5 , wherein the implantable device is a pulmonary implant.

8. A method for loading an implantable device into a container, comprising:
pulling an implantable device using a puller element through a loading tunnel in a loading element thereby contracting the implantable device into a compressed state of reduced size relative to an expanded state as the implantable device travels through the loading tunnel, wherein the puller element is removably attached to the implantable device via a suture including an attachment anchor;
automatically releasing the implantable device after the implantable device is contracted into the compressed state; and
pushing the implantable device through the loading tunnel and into a delivery catheter using a plunger.

9. The method of claim 8 , further comprising separating the puller element from the loading element.

10. The method of claim 8 , further comprising placing a portion of the delivery catheter into the loading element.

11. The method of claim 8 , wherein the implantable device is a pulmonary implant.

12. A method for loading an implantable device into a container, comprising:
pulling an implantable device using a puller element through a loading tunnel in a loading element thereby contracting the implantable device into a compressed state of reduced size relative to an expanded state as the implantable device travels through the loading tunnel, wherein the puller element is removably attached to the implantable device;
automatically releasing the implantable device after the implantable device is contracted into the compressed state;
wherein automatically releasing the implantable device after the implantable device is contracted into the compressed state comprises detaching a suture.

13. The method of claim 12 , wherein a rotator disposed on the puller element is removably attached to the suture; and wherein the suture is detached from the rotator by rotating the rotator.

14. The method of claim 13 , wherein the suture is drawn through and exits the implantable device after the detachment of the suture from the rotator thereby detaching the suture from the implantable device.

15. The method of claim 12 , wherein the implantable device is a pulmonary implant.
