Apparatus and methods for rapid deployment of tissue anchors
First Claim
1. A surgical method comprising:
- advancing a tissue grasping tool through a lumen to a surgical site in a patient, with the tissue grasping tool having first and second jaws and a needle within a tube;
engaging tissue of the patient at the surgical site with the tissue grasping tool by pushing on the tube to pivot the first and second jaws relatively towards each other;
advancing the needle through the engaged tissue, with the needle guided through the tube that is pivotably attached to the first jaw of the tissue grasping tool; and
pushing a tissue anchor out of the needle to secure the engaged tissue using a control handle positioned outside of the patient.

Abstract
Apparatus and methods for rapid deployment of tissue anchors are described herein. A tissue manipulation assembly is pivotably coupled to the distal end of a tubular member and has a lower jaw member and an upper jaw member pivotably coupled to the lower jaw member. A reconfigurable launch tube is pivotably coupled to the upper jaw member and is used to urge the jaw members from a low-profile configuration to an open configuration. A needle assembly can be advanced through the launch tube across tissue received between the jaw members of the tissue manipulation assembly. Tissue anchors can be advanced through the needle assembly for securing received tissue. The tissue anchors can be positioned within a reloadable chamber of a control handle disposed outside the patient, then advanced through the needle assembly.

2. A surgical method comprising:
-
moving a tissue grasping tool through a lumen to a surgical site in a patient, with the tissue grasping tool having first and second jaws; engaging tissue of the patient at the surgical site with the tissue grasping tool by moving the first and second jaws relatively towards each other by moving a launch tube that is pivotally attached to the first jaw; positioning a launch tube relative to the grasped tissue; moving a needle out of the launch tube and through a first opening in the first jaw, through the engaged tissue, and through a second opening in the second jaw; and moving a tissue anchor attached to a suture out of the needle. - View Dependent Claims (3)

4. A method of securing tissue within a hollow body organ, comprising:
-
endoluminally advancing a tissue grasping tool having first and second jaws into the hollow body organ; engaging tissue with the tissue grasping tool by moving the first and second jaws relatively towards each other by moving a launch tube that is pivotally attached to the first jaw; advancing a needle through the engaged tissue to thereby pierce the engaged tissue, with the needle guided through the launch tube; deploying a tissue anchor from the needle to secure the engaged tissue with the tissue anchor advanced to the tissue grasping tool from a control handle positioned outside of the hollow body organ; and withdrawing the needle back through the engaged tissue. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12, 13)
