Systems and techniques for performing gastrointestinal procedures

摘要

A system for performing minimally invasive gastrointestinal procedures includes an excision device 100 and a suturing device 200. The excision device 100 has a proximally tapered suction cavity with extendable wires 160 to prevent capture of unwanted tissue. The suturing device 200 uses a squeeze trigger to drive an array of circular needles.
