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.

Claims

1. A method of delivering a medical device to a delivery site within a patient, the method comprising:

releasably coupling a medical device with a deployment handle, the medical device including an expandable frame having a plurality of struts extending from a proximal end to a distal end of the frame;

arranging the medical device into an elongated configuration with the deployment handle by actuating a linear actuator within a slot to a proximal stopping position;

arranging the medical device into a deployed configuration by actuating the linear actuator within the slot to a distal stopping position subsequent to actuating the linear actuator to the proximal stopping position.

2. The method of claim 1, further comprising actuating a release actuator to release the medical device from the deployment handle.

3. The method of claim 1, wherein arranging the medical device into the elongated configuration includes withdrawing the medical device within a catheter lumen of the deployment handle.

4. The method of claim 1, wherein the expandable frame comprises a proximal central frame portion, and releasably coupling the medical device to the deployment handle includes coupling the proximal central frame portion to the deployment handle.

5. The method of claim 1, further comprising moving the at least one linear actuator laterally from a distal notch of the slot prior to withdrawing the at least one linear actuator proximally within the slot.

6. The method of claim 1, wherein the proximal stopping position is indicative of the medical device being arranged in the elongated configuration.

7. The method of claim 1, further comprising moving the at least one linear actuator laterally within the slot at the proximal stopping position into a proximal notch of the slot.

8. The method of claim 1, further comprising allowing the medical device to self-expand upon release from the deployment handle at the delivery site within the patient.

9. The method of claim 8, wherein the expandable frame comprises a shape memory alloy configured to self-expand upon release from the deployment handle.

10. The method of claim 1, wherein the deployment handle comprises a first tube extending from an end of the housing;

a second tube configured to retract within the first tube; and

a third tube configured to retract within the second tube.

11. The method of claim 10, wherein actuating the linear actuator within the slot comprising retracting the third tube within the second tub, and retracting the second tube within the first tube.

12. The method of claim 1, wherein the medical device comprises a substantially bell shape.

13. A method of delivering a medical device to a delivery site within a patient, comprising:

releasably coupling a medical device with a deployment handle, the deployment handle comprising a first tube extending from an end of the housing, a second tube configured to retract within the first tube, a third tube configured to retract within the second tube, a channel having a length portion arranged along at least a partial length of the housing, and at least one linear actuator configured to move within the channel along the length thereof, the medical device comprising an expandable frame having a plurality of struts extending from a proximal end to a distal end of the frame; and

transitioning the third tube within the second tube and the second tube within the first tube based on a position of the at least one linear actuator within the channel.

14. The method of claim 13, wherein the medical device comprises an elongated configuration and a deployed configuration.

15. The method of claim 14, further comprising actuating the at least one linear actuator to elongate the medical device to the elongated configuration by withdrawing the at least one linear actuator proximally within the channel.

16. The method of claim 15, wherein the channel comprises a distal notch and a proximal notch, the distal notch and the proximal notch being substantially perpendicular to the length portion of the channel.

17. The method of claim 16, wherein moving the at least one linear actuator from the distal notch prior to withdrawing the at least one linear actuator proximally within the slot to arrange the medical device in the elongated configuration.

18. A method for operating a deployment handle, the method comprising:

actuating at least one linear actuator within a channel arranged within a housing of the deployment handle, the deployment handle comprising a first tube extending from an end of the housing, a second tube configured to retract within the first tube, a third tube configured to retract within the second tube, and the channel having a length portion arranged along at least a partial length of the housing, and the at least one linear actuator being configured to move within the channel along the length thereof; and

transitioning the third tube within the second tube and the second tube within the first tube based on a position of the at least one linear actuator within the channel.

19. The method of claim 18, wherein further comprising releasably coupling a medical device to a deployment handle for delivery thereof.

20. The method of claim 19, wherein the medical device comprises an elongated configuration and a deployed configuration and transitioning the third tube within the second tube and the second tube within the first tube elongates the medical device to the elongated configuration in response to withdrawing the at least one linear actuator proximally within the channel.
