Devices, systems, and methods for treating the left atrial appendage

A system for treating a left atrial appendage, comprising:

• an implant configured to be at least partially positioned within the left atrial appendage;
• a catheter configured to deploy the implant;
• and
• a support stand for supporting the catheter and at least a guide catheter;
• wherein:
• the support stand is configured to be positioned on a support surface, such as a bed or table, or on a patient;
• and
• the catheter comprises:
• an outer sheath;
• an inner catheter member configured to rotate the implant when a distal end portion of the inner catheter member is engaged with the implant.

A device for treating a left atrial appendage, comprising:

• an implant comprising:
• a contact member configured to move between a first state and a second state;
• and
• a securing element;
• wherein:
• at least a portion of the contact member is larger in a radial direction when the implant is in the second state as compared to the first state;
• the contact member is configured to engage an inside tissue surface of the left atrial appendage and configured to rotate in at least a first direction from a first position to at least a second position so as to twist the left atrial appendage from a first position to at least a second position when the contact member is engaged with an inside tissue surface of the left atrial appendage;
• the securing element is configured to engage a tissue of the left atrium and/or the left atrial appendage to prevent the left atrial appendage that has been twisted to at least the second position from untwisting back to the first position of the left atrial appendage;
• the implant is configured so that rotating the contact member 90° or approximately 90° from the first position will cause the contact member to contact and rotate at least an end portion of the tissue of the left atrial appendage, and so that rotating the contact member from 90° or approximately 90° to 180° or approximately 180° will cause the tissue of the left atrial appendage to twist and constrict around the implant at least between the contact member and the securing element.
