Methods and Devices for Occlusion of an Atrial Appendage

A system for occluding a left atrial appendage of a patient, the system comprising:

• a clip occluder that can be positioned around the left atrial appendage, the clip occluder including a clip hinge coupled to an upper clip jaw and a lower clip jaw, the clip occluder including a clip lock;
• and
• a clip applicator to position the clip occluder with respect to the left atrial appendage,
• the clip applicator including a clip actuator coupled to the clip occluder by an actuator suture, the actuator suture controlling a distance between the upper clip jaw and the lower clip jaw,
• the clip applicator removably coupled to the clip occluder with a retention suture.

A clamp for occluding a left atrial appendage of a patient, the system comprising:

• an upper pressure plate;
• a lower pressure plate;
• at least one connector rod coupled to the upper pressure plate and the lower pressure plate, the at least one connector rod include a plurality of teeth;
• and
• at least one receiver coupled the at least one connector rod in order to engage the plurality of teeth, the at least one receiver being moveable to reduce a distance between the upper pressure plate and the lower pressure plate.

A clamp for occluding a left atrial appendage of a patient, the system comprising:

• an upper pressure plate having a first tie channel;
• a lower pressure plate having a second tie channel;
• and
• a tie positioned through the first tie channel and the second tie channel, the tie being moveable to reduce a distance between the upper pressure plate and the lower pressure plate.

A system for occluding a left atrial appendage of a patient, the system comprising:

• a loop clip occluder that can be positioned around the left atrial appendage, the loop clip occluder including a clip jaw, a loop, and a clip lock;
• and
• a loop clip applicator to position the loop clip occluder with respect to the left atrial appendage,
• the loop clip applicator including a loop clip actuator coupled to the loop clip occluder by an actuator suture, the actuator suture controlling movement of the loop with respect to the clip jaw and the clip lock,
• the loop clip applicator removably coupled to the loop clip occluder with a retention suture.

A system for occluding a left atrial appendage of a patient, the system comprising:

• a ring applicator including
• a shaft having a handle on a proximal end and a distal end, and a lumen extending from the handle to the distal end of the shaft,
• an actuator coupled to the handle, and
• a ring spreader assembly on the distal end of the shaft, the ring spreader assembly having a plurality of ring expanding members;
• and
• a ring occluder releasably attached to the plurality of ring expanding members, the ring occluder being stretched to an open position by the actuator to allow the ring occluder to be manipulated over tissue to be occluded.
