Abstract

Methods and devices for use in tissue approximation and fixation are described herein. The present invention provides, in part, methods and devices for acquiring tissue folds from the anterior and posterior portions of a hollow body organ, e.g., a stomach, positioning the tissue folds for affixing within a fixation zone of the stomach, preferably to create a pouch or partition below the esophagus, and fastening the tissue folds such that a tissue bridge forms excluding the pouch from the greater stomach cavity. The present invention further provides devices for performing a transoral, endoscopic hollow organ division, including a tissue acquisition device capable of acquiring the desired tissue, a tensioning device for positioning the acquired tissue, and a fastening element to secure the outer layers of the acquired tissue such that the desired healing response is achieved.

Independent Claims | See all claims (15)

  1. 1. A method of partitioning a hollow body organ from within, said method comprising: positioning a tissue acquisition device into the hollow body organ, said tissue acquisition device having a proximal end and distal end and a lumen therebetween with a tissue acquiring mechanism at the distal end thereof; acquiring a first tissue region and a second tissue region within at least one opening defined in said tissue acquiring mechanism such that said acquired tissue is in juxtaposition with each other; advancing a tissue fastening assembly within the lumen to the juxtaposed tissue, said tissue fastening assembly device having clamping distal portion; and actuating the clamping distal portion to engage said juxtaposed tissue with a fastening element such that said juxtaposed tissue remain affixed to one another.
  2. 14. A method of partitioning a hollow body organ from within, said method comprising: positioning a tissue acquisition device into the hollow body organ, said tissue acquisition device having a proximal end and a distal end and a lumen therebetween with a tissue acquiring mechanism at the distal end thereof; acquiring a first tissue region within at least one opening defined in said tissue acquiring mechanism such that said first tissue region acquires a partitioning configuration; advancing a tissue fastening assembly within the lumen to the first tissue region said tissue fastening assembly device having a clamping distal portion; actuating the clamping distal portion to engage said first tissue region with a fastening element such that said first tissue region within remains affixed in the partitioning configuration; and acquiring a second tissue region within the at least one opening such that the second tissue region is in juxtaposition with the first tissue region prior to actuating the clamping distal portion.
