 The StomaphyX delivery system with SerosaFuse fasteners consist of an ergonomic, flexible fastener delivery device and sterile polypropylene fastener implants. The unit is provided sterile and is a single use device. The polypropylene fasteners are proprietary and function only with the StomaphyX device. The device uses vacuum to invaginate tissue through a port into a chamber and fasten it using the H shaped polypropylene fasteners. The fastener delivery subsystem is comprised of 3 elements: stylet, pusher, and internal lumens. They run the length of the device, the pusher being a hollow tube that rides over the length of the stylet, both riding in the lumen. The stylet is sharp at the distal tip to pierce tissue. The fastener is loaded by snapping it onto the stylet in the loading port of the handle. When pushed by the operator, the stylet carries the fastener down the lumen which runs from the proximal handle assembly to the distal tissue port where it will eventually be deployed into the tissue. Durability of the SerosaFuse fasteners has been demonstrated during several clinical studies utilizing the EsophyX device 9-12.
