Single fold system for tissue approximation and fixation
First Claim
1. A tissue acquisition and fixation system comprising:
- a tissue acquisition device having an elongate main body defining a main lumen therethrough, a distal end of the acquisition device having a tissue adhering member adapted to acquire tissue from within a hollow body organ including a vacuum pod aligned on an axis of the main lumen and displaceable in a first radial direction, and first and second cavities located on opposite sides of the vacuum pod, and a tissue tensioning member adapted to tension the acquired tissue having first and second rods defining a fixed opening therebetween, where the vacuum pod is disposed in the fixed opening when the first and second rods are seated in the first and second cavities, respectively, the tissue tensioning member positioned for receiving the acquired tissue therein and wherein the tensioning member is displaceable in a second radial direction opposite the first radial direction; and
a tissue fixation device adapted to be advanced through the main lumen and extending between the opening defined by the first and second rods and the vacuum pod for affixing the acquired tissue.

Abstract
A single fold system for tissue approximation and fixation is described herein. The devices are advanced in a minimally invasive manner within a patient'"'"'s body to create at least one fold within a hollow body organ. The system comprises a tissue acquisition and folding device and a tissue stapling or fixation device, each of which is used together as a system. The acquisition device is used to approximate a single fold of tissue from within the hollow body organ and the stapling device is advanced through a main lumen defined through the acquisition device and is used to affix the tissue. The stapling device is keyed to maintain its rotational orientation relative to the acquisition device and to provide the user positional information of the stapling device. The acquisition device is also configured to provide lateral stability to the stapling device prior to the stapling device being clamped onto tissue.
