US 7,914,543 B2 · Single fold device for tissue fixation

Abstract

A system for tissue approximation and fixation is described herein. A device is advanced in a minimally invasive manner within a patient's body to create one or several divisions or plications within a hollow body organ. The system comprises a stapler assembly having a tissue acquisition member and a tissue fixation member. The stapler assembly approximates tissue from within the hollow body organ with the acquisition member and then affixes the approximated tissue with the fixation member. In one method, the system can be used as a secondary procedure to reduce the size of a stoma within the hollow body organ.

Dependent claims

A tissue fixation device, comprising:

an elongated body having a proximal end and a distal end;
a tissue fixation assembly connected to the distal end of the elongated body having an acquisition member for acquiring tissue and a fixation member having staples for stapling tissue acquired by the acquisition member;
wherein the acquisition member is integrated into a portion of the fixation member and wherein the acquisition member defines at least one opening adapted to adhere tissue thereto via a vacuum;
and
wherein a hinge member pivotally connects the fixation assembly to the distal end of the elongated body.
