Abstract

Medical devices and delivery systems for delivering medical devices to a target location within a subject. In some embodiments the medical devices can be locked in a fully deployed and locked configuration. In some embodiments the delivery systems are configured with a single actuator to control the movement of multiple components of the delivery system. In some embodiments the actuator controls the independent and dependent movement of multiple components of the delivery system.

Claims

1. A method of deploying a medical device in a patient with a delivery system, comprising:

providing a delivery system comprising a housing disposed external to the patient, wherein the housing comprises an actuator;

actuating the actuator to move a first delivery system component independently of a second delivery system component;

actuating the actuator to move the first delivery system component and the second delivery system component at the same time; and

rotating the actuator to translate rotational movement into linear movement.

2. The method of claim 1, wherein actuating the first and second delivery system components comprises actuating the actuator with a singular type of motion.

3. The method of claim 1, wherein the acts of actuating the actuator actuate the first and second delivery system components in a particular sequence.

4. The method of claim 1, wherein the actuator is a first actuator, and wherein the housing further comprises a second actuator, the method further comprising:

actuating the second actuator to uncouple the second delivery system component from the medical device.

5. The method of claim 4, wherein actuating the second actuator to uncouple the second delivery system component from the medical device further comprises:

retracting a pin assembly of the delivery system.

6. The method of claim 4, wherein the housing further comprises an access door, the method further comprising:

moving the access door to access the second actuator.

7. The method of claim 1 wherein the delivery system further comprises a first gear and a second gear, wherein the actuator turns both the first gear and the second gear;

wherein the first delivery system component is coupled to the first gear and engaged to the actuation element; and

wherein the second delivery system component is coupled to the second gear and engaged to the sheath.

8. The method of claim 7, wherein the delivery system further comprises:

a first lead screw that couples the first delivery system component to the first gear; and

a second lead screw that couples the second delivery system component to the second gear;

wherein the first gear is geared to the first lead screw, and

wherein the second gear is geared to the second lead screw.

9. The method of claim 8, wherein the first lead screw has a first pitch and the second lead screw has a second pitch, the first pitch being different from the second pitch.

10. The method of claim 8, wherein the delivery system further comprises:

a first spring engaged to the first lead screw; and

a second spring engaged to the second lead screw; and

the method further comprises;

turning the first gear to uncompress the first spring and move the first delivery system component, and

turning the second gear to compress the second spring and move the second delivery system component.

11. A method of deploying a medical device in a patient with a delivery system, comprising:

providing a delivery system comprising a housing disposed external to the patient, wherein the housing comprises a first actuator and a second actuator;

actuating the first actuator to move a first delivery system component independently of a second delivery system component;

actuating the first actuator to move the first delivery system component and the second delivery system component at the same time;

rotating the first actuator to translate rotational movement into linear movement; and

actuating the second actuator to uncouple the second delivery system component from the medical device.
