Automated heart valve manufacturing
An automated system that can be used for prosthetic heart valve manufacturing or suturing procedures. The system can include a first automated fixture that includes an articulating arm and a target device holder. The system can also include one or more additional automated fixtures, which can be configured as one or more suturing arms that include another articulating arm and a needle holder. The first automated fixture can be configured to rotate a target device held by the holder to allow the one or more additional automated fixtures to perform operations such as form sutures on the target device without intervention of a human operator. The system can include a display system configured to display status information of a suturing procedure.
1. A method for forming sutures on a target device using a fully automated system, the method comprising:
maneuvering a target device by automatically manipulating components of an automated suture fixture comprising a target holder, the target device secured by the target holder;
maneuvering a needle to perform a first step in forming a suture on the target device, the needle secured by a first suturing arm with a first needle holder during the first step;
maneuvering the needle to perform a second step in forming a suture on the target device, the needle secured by a second suturing arm with a second needle holder during the second step; and
passing the needle from the first needle holder to the second needle holder to transition between the first step to the second step, wherein passing the needle from the first needle holder to the second needle holder includes passing the needle through a material of the target device.
2. The method of claim 1 , wherein the automated suture fixture comprises a plurality of motorized actuator devices coupled to the target holder.
3. The method of claim 2 , wherein the first suturing arm comprises a plurality of motorized actuator devices coupled to the first needle holder.
4. The method of claim 3 , wherein the second suturing arm comprises a plurality of motorized actuator devices coupled to the second needle holder.
5. The method of claim 1 , wherein the first step in forming the suture and the second step in forming the suture are part of a pre-programmed suturing procedure.
6. The method of claim 5 further comprising sending control signals from a controller to the automated suture fixture, to the first suturing arm, and to the second suturing arm to perform the pre-programmed suturing procedure.
7. The method of claim of claim 6 further comprising sending feedback signals to the controller from a targeting system configured to acquire images of the target device.
8. The method of claim 7 , wherein the feedback provided by the targeting system is configured to adjust the first suturing arm to target the needle to specified points on the target device.
9. The method of claim 5 , wherein the pre-programmed suturing procedure includes a data set representing a plurality of positions of the automated suture fixture, the first suturing arm, and the second suturing arm.
10. The method of claim 1 , wherein the target device is a prosthetic human heart valve implant device.
11. A method for forming sutures on a target device using a fully automated system, the method comprising:
maneuvering a target device by automatically manipulating components of an automated suture fixture comprising a target holder, the target device secured by the target holder;
maneuvering a needle to perform a first operation of a suturing procedure on the target device, the needle secured by a first suturing arm with a first needle holder during the first operation;
maneuvering the needle to perform a second operation of the suturing procedure on the target device, the needle secured by a second suturing arm with a second needle holder during the second operation; and
securing the needle in a needle transfer fixture during a portion of the suturing procedure to allow the second first suturing arm to adjust an orientation of the needle relative to the first needle holder.
12. The method of claim 11 further comprising passing the needle from the first needle holder to the second needle holder to transition between the first operation and the second operation.
13. The method of claim 12 , wherein passing the needle from the first needle holder to the second needle holder includes passing the needle through a material of the target device.
14. The method of claim 11 , wherein the suturing procedure is configured to perform a plurality of sutures on the target device.
15. The method of claim 11 , wherein the needle transfer fixture remains in a fixed position during the suturing procedure.
16. The method of claim 11 , wherein the needle transfer fixture includes a magnet to secure the needle.
17. The method of claim 11 , wherein the automated suture fixture comprises a plurality of motorized actuator devices coupled to the target holder.
18. The method of claim 17 , wherein the first suturing arm comprises a plurality of motorized actuator devices coupled to the first needle holder.
19. The method of claim 18 , wherein the second suturing arm comprises a plurality of motorized actuator devices coupled to the second needle holder.
20. The method of claim 11 , wherein the target device is a prosthetic human heart valve implant device.
