1. A system for delivering a sealing device into a heart, the system comprising:
- a sealing device;
a housing having a slot, the slot comprising a first portion and a second portion;
a first tube configured to be releasably coupled to a proximal end portion of the sealing device;
a second tube configured to be releasably coupled to a distal end portion of the sealing device; and
a first linear actuator located within the slot of the housing, the first linear actuator being configured to advance the first tube, the second tube, and the sealing device when the first linear actuator is advanced along the slot of the housing and the sealing device is coupled to the proximal and distal end portions of the first and second tubes, respectively, and the first linear actuator being configured to retract the first tube, the second tube, and the sealing device when the first linear actuator is retracted along the slot of the housing and the sealing device is coupled to the proximal and distal end portions of the first and second tubes, respectively,wherein advancing or retracting the first linear actuator along the first portion of the slot advances or retracts the first tube without advancing or retracting the second tube, and wherein advancing or retracting the first linear actuator along the second portion of the slot advances or retracts the first tube and the second tube.

Abstract
The invention relates to a sealing device for repair of cardiac and vascular defects or tissue opening such as a patent foramen ovale (PFO) or shunt in the heart, the vascular system, etc. and particularly provides an occluder device and trans-catheter occluder delivery system. The sealing device would have improved conformity to heart anatomy and be easily deployed, repositioned, and retrieved at the opening site.
