Devices and methods for endoluminal plication

摘要

Devices and methods are provided for forming and securing a tissue plication. More particularly, the devices and methods of the present invention can be used to create multiple tissue folds on an anterior and posterior wall of a stomach cavity to reduce the volume thereof. In one aspect, a tissue acquisition and fixation system is disclosed including a stapling member having first and second jaws that are effective to apply at least one staple to tissue engaged between the jaws, a tissue acquisition member coupled to at least one of the first and second jaws, and a secondary tissue acquirer coupled to the tissue acquisition member. The secondary tissue acquirer is configured to engage tissue and maintain the tissue in position relative to the tissue acquisition member.

主权项

1. A tissue acquisition and fixation system, comprising:
a stapling member having first and second jaws and a longitudinal axis extending from a proximal end to a distal end thereof, at least the first jaw being configured to move between an open position for receiving tissue and a closed position for engaging tissue, the first and second jaws being effective to apply at least one staple in a direction transverse to the longitudinal axis of the staple applying assembly to tissue engaged between the first and second jaws; a tissue acquisition member coupled to at least the first jaw and configured to engage tissue and position the tissue between the first and second jaws; and a secondary tissue acquirer coupled to the tissue acquisition member and configured to engage tissue and maintain the tissue in position relative to the tissue acquisition member; wherein movement of the first jaw between the open and closed position is effective to cause corresponding movement of the tissue acquisition member and secondary tissue acquirer.
