Abstract

Methods, systems, devices and assemblies are provided for treating a patient by: making an incision or puncture though the patient'"'"'s skin over the abdominal cavity; establishing an initial tract through an opening formed by the incision or puncture; advancing an instrument through the tract; contacting a distal end portion of the instrument against an inner surface of the abdominal cavity; driving at least one stitching needle through the inner surface of the abdominal cavity; continuing the driving until the at least one stitching needle exits the inner surface of the abdominal cavity; anchoring a suture carried by each of the at least one stitching needle to a suture anchor at an exit location, respectively; and applying tension to each of the sutures.

Claims

1. A method of treating a patient said method comprising:

making an incision or puncture though the patient'"'"'s skin over the abdominal cavity,

establishing an initial tract through an opening formed by the incision or puncture;

advancing an instrument through the tract;

contacting a distal end portion of the instrument against an inner surface of the abdominal cavity;

driving at least one stitching needle through the inner surface of the abdominal cavity, until said at least one stitching needle exits the inner surface of the abdominal cavity;

anchoring a suture carried by each said at least one stitching needle to a suture anchor at an exit location, respectively; and

applying tension to each said suture.

2. The method of claim 1, further comprising cutting an excess portion of each said suture.

3. The method of claim 1, wherein an implant is mounted on the instrument during said advancing an instrument and wherein said at least one suture attaches said implant to the inner surface of the abdominal cavity upon completing said driving, anchoring, and applying tension.

4. The method of claim 3, wherein a suture retainer corresponding to each suture is mounted on said implant.

5. The method of claim 3, wherein the implant is expandable.

6. The method of claim 5, wherein said implant is attached to internal abdominal fascia of the abdominal cavity.

7. The method of claim 1, further comprising driving at least one stabilizing pin per each said stitching needle into the inner surface of the abdominal cavity adjacent said initial location after said contacting a distal end portion of the instrument against the inner surface of the abdominal cavity, but before said driving at least one stitching needle into the inner surface of the abdominal cavity.

8. The method of claim 7, wherein each said stabilizing pin is driven at an angle to a main shaft of said instrument, in a direction away from a direction defined from said initial location to said exit location, respectively.

9. The method of claim 1, wherein said instrument comprises an attachment tool and a suturing tool that are releasably connected and wherein a suture anchor for each suture anchored is releasably connected to said attachment tool, wherein said method comprises:

disconnecting said attachment tool from each said suture anchor after said anchoring a suture;

disconnecting said attachment tool from said suturing tool; and

removing said attachment tool from said tract and from said patient, prior to said applying tension to each said suture, wherein said applying tension is carried out using said suturing tool.

10. The method of claim 3, wherein said instrument comprises an attachment tool and a suturing tool that are releasably connected and wherein a suture anchor for each suture anchored is releasably connected to said attachment tool, wherein said method comprises:

disconnecting said attachment tool from said implant and each said suture anchor after said anchoring a suture;

disconnecting said attachment tool from said suturing tool; and

removing said attachment tool from said tract and from said patient, prior to said applying tension to each said suture, wherein said applying tension is carried out using said suturing tool.

11. The method of claim 7, wherein said instrument comprises an attachment tool and a suturing tool that are releasably connected and wherein a suture anchor for each suture anchored is releasably connected to said attachment tool, wherein said method comprises:

retracting said stabilizing pins from the surgical target retracting said at least one stitching needle from the abdominal wall; and

disconnecting said attachment tool from each said suture anchor after said anchoring a suture;

disconnecting said attachment tool from said suturing tool; and

removing said attachment tool from said tract and from said patient, prior to said applying tension to each said suture, wherein said applying tension is carried out using said suturing tool.

12. The method of claim 1, further comprising releasing a safety switch prior to said driving at least one stitching needle into the surgical target at an initial location, wherein said safety switch, prior to said releasing, prevents said driving.

13. The method of claim 5, further comprising:

expanding the implant after said contacting a distal end portion of the instrument against the inner surface of the abdominal cavity;

viewing a position and orientation of the expanded implant in the patient; and

performing said driving at least one stitching needle when an operator determines that said position and orientation of the expanded implant are satisfactory.

14. The method of claim 12, further comprising cutting an excess portion of each said suture at a location proximal of a location wherein each said suture is retained by a suture retainer, respectively, using a cutting feature of said suturing tool.

15. The method of claim 14, further comprising:

removing the suturing tool from the tract and from the patient;

connecting a port in fluid communication with said implant;

inserting the port through the incision or puncture;

securing the port to fascia of the patient; and

closing the incision or puncture.
