Abstract

A recapturable external LAA exclusion clip system includes a clip comprising first and second clip struts, at least one of the struts having a connector interface comprising a first portion of a lock, and a delivery device comprising a handle and an end effector. The handle comprises jaw and lock controls. The end effector is connected to the handle and comprises a clevis and first and second jaws. The jaws are connected to the clevis and operatively connected to the jaw control to actively articulate at least one of the jaws with respect to the other. At least one of the jaws has a connector comprising a second portion of the lock operatively connected to the lock control to removably lock with the first portion of the lock. The first and second portions of the lock have a locked state and are configured to unlock the locked state upon actuation of the lock control.

First claim

What is claimed is:

1. An external left atrial appendage (LAA) exclusion clip recapture system, comprising:
an LAA exclusion clip comprising:
a first clip strut comprising a first connector interface; and
a second clip strut comprising a second connector interface, at least one of the first and second connector interfaces comprising a first portion of a lock; and

a delivery and recapture device comprising:
a handle comprising a jaw control and a lock control; and
an end effector connected to the handle and comprising:
a clevis; and
first and second jaws:
connected to the clevis;
biased towards a closed orientation;
operatively connected to the jaw control to actively articulate at least one of the first and second jaws with respect to the other;
having respective first and second connectors, the first connector of the first jaw having a given length and the second connector of the second jaw having a length different from the given length; and
at least one of the first and second connectors comprising a second portion of the lock and being operatively connected to the lock control to removably lock with the first portion of the lock.

2. The system according to claim 1 , wherein:
the first connector is a first internal connector shaped to connect within either of the first and second connector interfaces; and
the second connector is a second internal connector shaped to connect within either of the first and second connector interfaces.

3. The system according to claim 1 , wherein:
the first connector interface is a longitudinal bore; and
the second connector interface is a longitudinal bore.

4. The system according to claim 1 , wherein at least one of the first and second connectors is pivotably connected to a respective one of the first and second jaws, is biased to an approximately parallel orientation with respect to the other one of the first and second connectors, and is configured to pivot passively from the approximately parallel orientation.

5. The system according to claim 4 , wherein the at least one of the first and second connectors is configured to pivot passively in a range from the approximately parallel orientation to an angle approximately +/−30°.

6. The system according to claim 1 , wherein the first and second connectors are respectively independently pivotably connected to a respective one of the first and second jaws, are biased to an approximately parallel orientation, and are each configured to pivot passively from the approximately parallel orientation.

7. The system according to claim 6 , wherein the at least one of the first and second connectors is configured to pivot passively in a range from the approximately parallel orientation to an angle approximately +/−30°.

8. The system according to claim 1 , wherein the first and second connectors are each pivotably connected such that, while a longer one of the first and second connectors is at least partially inserted within one of the first and second connector interfaces, motion of the handle allows a user to passively align a shorter one of the first and second connectors into the other one of the first and second connector interfaces.

9. The system according to claim 1 , wherein:
both of the first and second connector interfaces comprise the first portion of the lock; and
both of the first and second connectors comprise the second portion of the lock and are each operatively connected to the lock control to removably lock with the respective first portion of the lock.

10. The system according to claim 9 , wherein the first and second portions of the lock have a locked state and are configured:
to unlock the locked state upon actuation of the lock control; and
after having been released, to automatically re-enter the locked state as the first and second portions of the lock are moved back together.

11. The system according to claim 1 , wherein the first and second portions of the lock have a locked state and are configured:
to unlock the locked state upon actuation of the lock control; and
after having been released, to automatically re-enter the locked state as the first and second portions of the lock are moved back together.

12. The system according to claim 1 , wherein the first and second connectors are cylindrical pins.

13. An external left atrial appendage (LAA) exclusion clip recapture system, comprising:
an LAA exclusion clip comprising:
a first clip strut comprising a first connector interface; and
a second clip strut comprising a second connector interface, at least one of the first and second connector interfaces comprising a first portion of a lock; and

a delivery and recapture device comprising:
a handle comprising a jaw control and a lock control; and
an end effector connected to the handle and comprising:
a clevis; and
first and second jaws:
each pivotably connected to the clevis and are operatively connected to the jaw control to actively articulate with respect to one another;
operatively connected to the jaw control to actively articulate at least one of the first and second jaws with respect to the other;
having respective first and second connectors, the first connector of the first jaw having a given length and the second connector of the second jaw having a length different from the given length; and
at least one of the first and second connectors comprising a second portion of the lock and being operatively connected to the lock control to removably lock with the first portion of the lock.

14. The system according to claim 13 , wherein:
the first connector is a first internal connector shaped to connect within either of the first and second connector interfaces; and
the second connector is a second internal connector shaped to connect within either of the first and second connector interfaces.

15. The system according to claim 13 , wherein:
the first connector interface is a longitudinal bore; and
the second connector interface is a longitudinal bore.

16. The system according to claim 13 , wherein at least one of the first and second connectors is pivotably connected to a respective one of the first and second jaws, is biased to an approximately parallel orientation with respect to the other one of the first and second connectors, and is configured to pivot passively from the approximately parallel orientation.

17. The system according to claim 16 , wherein the at least one of the first and second connectors is configured to pivot passively in a range from the approximately parallel orientation to an angle approximately +/−30°.

18. The system according to claim 13 , wherein the first and second connectors are respectively independently pivotably connected to a respective one of the first and second jaws, are biased to an approximately parallel orientation, and are each configured to pivot passively from the approximately parallel orientation.

19. The system according to claim 18 , wherein the at least one of the first and second connectors is configured to pivot passively in a range from the approximately parallel orientation to an angle approximately +/−30°.

20. The system according to claim 13 , wherein the first and second connectors are each pivotably connected such that, while a longer one of the first and second connectors is at least partially inserted within one of the first and second connector interfaces, motion of the handle allows a user to passively align a shorter one of the first and second connectors into the other one of the first and s
