Multi-actuating trigger anchor delivery system
View Patent ↗A single trigger system and associated method for manipulating tissues and anatomical or other structures in medical applications for the purpose of treating diseases or disorders or other purposes. In one aspect, the system includes a delivery device configured to deploy and implant anchor devices for such purposes.
1. A method for implanting anchor assemblies using an anchor delivery device including a trigger and configured to deploy a plurality of anchor assemblies each including members that are joined partially or wholly in situ, comprising:
gaining access to an interventional site;
placing the anchor delivery device at the interventional site;
actuating the trigger one or more times to accomplish complete delivery of a first anchor assembly such that the first anchor assembly is placed in its final configuration; and
actuating the trigger one or more additional times to accomplish complete delivery of a second anchor assembly without removing the anchor delivery device from the interventional site subsequent to the complete delivery of the first anchor assembly.
2. The method of claim 1 , the anchor delivery device including a reset mechanism, comprising permitting the reset mechanism to prepare the anchor delivery device for delivery of the second anchor assembly subsequent to delivery of the first anchor assembly.
3. The method of claim 2 , the reset mechanism including a handle, comprising actuating the handle to reset the reset mechanism.
4. The method of claim 1 , comprising assembling the first anchor assembly in situ.
5. The method of claim 4 , comprising assembling the second anchor assembly in situ.
6. The method of claim 1 , the anchor delivery device including a needle assembly, comprising actuating the trigger to advance the needle assembly.
7. The method of claim 6 , the needle assembly retaining a first component of the first anchor assembly, comprising actuating the trigger to eject the first component of the first anchor assembly from the needle assembly.
8. The method of claim 7 , comprising withdrawing the needle assembly.
9. The method of claim 8 , the anchor delivery device including a pusher assembly and housing a plurality of first and second parts for forming second components of a plurality of first anchor assemblies, comprising actuating the trigger to cause the pusher assembly to advance one first part into engagement with one second part of the second component.
10. The method of claim 9 , the plurality of anchor assemblies including a connector, comprising actuating the trigger to sever the connector of the first anchor assembly.
11. The method of claim 10 , comprising assembling the second anchor assembly in situ.
12. The method of claim 10 , the needle assembly retaining a first component of the second anchor assembly, comprising actuating the trigger to eject the first component of the second anchor assembly from the needle assembly.
13. The method of claim 12 , the anchor delivery device housing a plurality of first and second parts for forming second components of a plurality of second anchor assemblies, comprising actuating the trigger to cause the pusher assembly to advance one first part of the second component of the second anchor assembly into engagement with one second part of the second component of the second anchor assembly.
14. The method of claim 13 , comprising actuating the trigger to sever a connection of the second anchor assembly.
15. The method of claim 14 , comprising assembling the second anchor assembly in situ.
