Medical devices and delivery systems for delivering medical devices
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.
1. A medical device system, including:
a delivery system comprising a housing disposed external to a subject,
wherein the housing comprises one or more actuators,
wherein the delivery system is configured and arranged such that a single actuator of the one or more actuators is adapted to move a first delivery system component independently of and without moving a second delivery system component, and
wherein the delivery system is further configured and arranged such that the single actuator is also adapted to move the second delivery system component independently of and without moving the first delivery system component.
2. The medical device system of claim 1 wherein the delivery system is further configured and arranged such that the single actuator is further adapted to actuate the first delivery system component and the second delivery system component simultaneously.
3. The medical device system of claim 2 wherein the single actuator is adapted to actuate the first delivery component and the second delivery system component at different rates when actuating them simultaneously.
4. The system of claim 1 wherein the delivery system is configured such that actuation of the single actuator moves the first and second delivery system components in the same direction.
5. The system of claim 1 wherein the delivery system is configured such that actuation of the single actuator actuates the first and second delivery system components in a specific sequence.
6. The system of claim 1 wherein the single actuator is configured such that actuation of the single actuator in a single type of motion causes both the actuation of the first delivery system component independent of the second delivery system component and the actuation of the second delivery system component independent of the first delivery system component.
7. The medical device system of claim 1 wherein the first delivery system component is a delivery sheath, and wherein the medical device system comprises a medical device adapted to be percutaneously delivered to a target location in a patient through the delivery sheath, and wherein the single actuator is adapted to move the delivery sheath independently of and prior to the independent movement of the second delivery system component.
8. The medical device system of claim 7 wherein the second delivery system component is reversibly coupled to a portion of the medical device.
9. The medical device system of claim 8 wherein the single actuator is adapted to independently move both the sheath and the second delivery component proximally when actuated.
10. The medical device system of claim 9 wherein actuation of the single actuator is configured to proximally retract the sheath to allow the medical device to expand, and wherein further actuation of the single actuator retracts the second delivery system component proximally.
11. The system of claim 1 wherein the delivery system and the single actuator are configured such that movement of the single actuator in a singular type of motion moves the first delivery system component independently of a second delivery system component and moves the second delivery system component independently of the first delivery system component.
12. The system of claim 11 wherein the singular type of motion is rotation of the single actuator.
13. The system of claim 11 wherein the singular type of motion moves the first delivery system component independently of a second delivery system component and moves the second delivery system component independently of the first delivery system component without any intervening actuation steps being performed between the independent movement of the first delivery system component and the independent movement of the second delivery system component.
14. A method of using a delivery system to deploy a medical device in a patient, comprising:
providing a delivery system comprising a housing disposed external to the patient, wherein the housing comprises one or more actuators;
actuating a single actuator of the one or more actuators to move a first delivery system component independently of and without moving a second delivery system component; and
actuating the single actuator to move the second delivery system component independently of and without moving the first delivery system component.
15. The method of claim 14 further comprising actuating the single actuator to move the first and second delivery system components simultaneously.
16. The method of claim 15 wherein actuating the single actuator comprises actuating the single actuator in a singular type of motion to move the first and second delivery system components independently of one another, as well as to move the first and second delivery system components simultaneously.
17. The method of claim 15 wherein actuating the single actuator moves the first and second delivery system components at different rates at least during a portion of the time they are being moved simultaneously.
18. The method of claim 14 wherein actuating the single actuator moves the first and second delivery system components in the same direction.
19. The method of claim 14 wherein actuating the single actuator moves the first and second delivery system components in a specific sequence.
20. The method claim 14 wherein actuating the single actuator comprises actuating the single actuator in a singular type of motion to move both the first and second delivery system components independently of one another.
21. The method of claim 20 wherein the singular type of motion is rotation in a single direction.
22. The method of claim 14 wherein the first delivery system component is a delivery sheath, and wherein actuating the single actuator comprises moving the delivery sheath in a proximal direction independently of and prior to the independent movement of the second delivery system component.
23. The method of claim 22 wherein the second delivery system component is reversibly coupled to a medical implant, and wherein actuation of the second delivery system component independently moves the second delivery system component in a proximal direction independently of and subsequent to the proximal movement of the delivery sheath.
24. The method of claim 14 wherein moving the first and second delivery system components comprises moving the first and second delivery system components proximally.
25. The method of claim 14 wherein actuating the single actuator to move the first delivery system component comprises moving a delivery sheath proximally to allow the medical device to expand.
