Abstract

Claims (45)

1 . A method of positioning an occlusion clip proximate a left atrial appendage, the method comprising:

creating an access port allowing communication between an exterior of a human body and an interior of the human body that exposes the left atrial appendage;

delivering a suction grasper via the access port, the suction grasper including opposing jaws each having a suction port;

delivering the occlusion clip via the access port;

grasping the left atrial appendage via the suction grasper by applying suction to an exterior of the left atrial appendage so that a portion of the left atrial appendage interposes the opposing jaws while suction is applied via the suction ports;

repositioning the suction grasper to tension the left atrial appendage;

overcoming a bias of the occlusion clip to open the occlusion clip, where the occlusion clip is biased closed, and position dual beams of the occlusion clip at least partially around the left atrial appendage;

discontinuing overcoming of the bias of the occlusion clip to clamp a base of the left atrial appendage using the dual beams of the occlusion clip while the suction grasper applies tension to the left atrial appendage; and

disconnecting the suction grasper from the left atrial appendage and egressing the suction grasper via the access port to the exterior of the human body.

2 . The method of claim 1 ,

wherein the opposing jaws of the suction grasper are resiliently connected to one another; and

wherein grasping the left atrial appendage comprises repositioning at least one of the opposing jaws with respect to the another of the opposing jaws.

3 . The method of claim 1 ,

wherein the opposing jaws of the suction grasper are repositionably coupled to one another so that at least a first of the opposing jaws is independently repositionable with respect to at least a second of the opposing jaws; and

wherein grasping the left atrial appendage comprises repositioning at least one of the opposing jaws with respect to the another of the opposing jaws.

4 . The method of claim 1 , wherein creating the access point comprises making a sub-xiphoid incision.

5 . The method of claim 1 , wherein creating the access point comprises making a sub-costal incision.

6 . The method of claim 1 , wherein creating the access point comprises inserting at least one of a sleeve and a cannula into an incision.

7 . The method of claim 1 , wherein delivering the occlusion clip comprises inserting a clip applier, operatively coupled to the occlusion clip, via the access port.

8 . The method of claim 1 ,

wherein the suction grasper comprises a malleable shaft; and

wherein the method further comprises bending the shaft.

9 . The method of claim 1 , wherein grasping the left atrial appendage via the suction grasper comprises operating a jaw actuator disposed on a handle of the suction grasper to articulate at least one of the opposing jaws.

10 . A method of positioning an occlusion clip proximate a left atrial appendage, the method comprising:

creating an access port allowing communication between an exterior of a human body and an interior of the human body that exposes the left atrial appendage;

delivering a suction grasper via the access port, the suction grasper including opposing jaws each having a suction port;

delivering the occlusion clip via the access port to be positioned at least partially around the left atrial appendage;

grasping the left atrial appendage via the suction grasper, after the occlusion clip is positioned at least partially around the left atrial appendage, by applying suction to an exterior of the left atrial appendage so that a portion of the left atrial appendage interposes the opposing jaws while suction is applied via the suction ports;

repositioning the suction grasper to tension the left atrial appendage;

clamping a base of the left atrial appendage using beams of the occlusion clip while the suction grasper applies tension to the left atrial appendage; and

disconnecting the suction grasper from the left atrial appendage and egressing the suction grasper via the access port to the exterior of the human body.

11 . The method of claim 10 , wherein:

the opposing jaws of the suction grasper are resiliently connected to one another; and

grasping the left atrial appendage comprises repositioning at least one of the opposing jaws with respect to the another of the opposing jaws.

12 . The method of claim 10 , wherein:

the opposing jaws of the suction grasper are repositionably coupled to one another so that at least a first of the opposing jaws is independently repositionable with respect to at least a second of the opposing jaws; and

grasping the left atrial appendage comprises repositioning at least one of the opposing jaws with respect to the another of the opposing jaws.

13 . The method of claim 10 , wherein creating the access point comprises making a sub-xiphoid incision.

14 . The method of claim 10 , wherein creating the access point comprises making a sub-costal incision.

15 . The method of claim 10 , wherein creating the access point comprises inserting at least one of a sleeve and a cannula into an incision.

16 . The method of claim 10 , wherein delivering the occlusion clip comprises inserting a clip applier, operatively coupled to the occlusion clip, via the access port.

17 . The method of claim 10 , wherein:

the suction grasper comprises a malleable shaft; and

the method further comprises bending the shaft.

18 . The method of claim 10 , wherein grasping the left atrial appendage via the suction grasper comprises operating a jaw actuator disposed on a handle of the suction grasper to articulate at least one of the opposing jaws.
