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, and a tissue tensioning member adapted to tension the acquired tissue; and
a tissue fixation device adapted to be advanced through the main lumen 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.

40. A method of acquiring and affixing tissue from within a hollow body organ, comprising:
-
acquiring at least one region of tissue from within the hollow body organ via a tissue adhering member;
articulating the tissue adhering member such that the acquired tissue is approximated through a tissue tensioning member to form a folded region of tissue between the tissue adhering member and tissue tensioning member; and
affixing the folded region of tissue via a cartridge assembly. - View Dependent Claims (41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52)
