摘要:
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.
