SUTURING DEVICES AND METHODS

摘要

Disclosed is a T-fastener delivery device. The device includes a belt and a pusher rod. The belt includes a plurality of slots for holding a plurality of T-bars substantially parallel to one another in a side­by-side arrangement; and the belt is moveable such that the slots can be sequentially aligned with the pusher rod. Also disclosed are methods for creating a gastric pouch in the stomach of an obese patient and methods for reducing lower esophageal sphincter distraction with gastric filling in a subject. Suturing systems are also disclosed. One suturing system includes a plurality of T-fasteners and a continuous suture connecting the plurality of T-fasteners. The T-fastener comprises a cylindrical bar having a filament loop attached thereto substantially at the cylindrical bar's axial midpoint, and the continuous suture slidably passes through the T-­fasteners' filament loops. Another suturing system includes a plurality of T-fasteners; and a continuous suture connecting the plurality of T-fasteners. The T­-fastener comprises two cylindrical bars connected by a filament, and the continuous suture slidably passes through a loop formed by the T-fasteners' filaments.
