A suturing device of the present invention is in the form a compact, light-weight handheld device that includes a needle and suture assembly, a mechamsm for gripping and releasing the needle/suture (a "needle transfer mechanism" or "needle shuttle mechanism"), safely capturing the needle/suture upon exit from the patient's tissue, and returning the needle to a position such that the process of delivering additional sutures to the patient can be repeated. A safety shield mechanism ensures the user is protected from the needle at all times. The device of the present invention accommodates the right or left-handed user, rests comfortably in the user's hand, allows sufficient visualization of the procedure site, and permits the user to either control penetration depth of the needle or default to a device- determined depth.

METHOD AND INSTRUMENT FOR THERMAL SUTURE CUTTING

Novel suture removal instrument and technique are described herein. The invention utilizes a newly designed thermal filament to allow the tip of the suture removal instrument to be slipped under the stitch in order to heat and cut the stitch. Current suture removal techniques utilize scissors, forceps, and/or scalpels. These techniques, which are well known in the art, are problematic because they exert tension on the stitch and are associated with patient. discomfort. Small stitches add to the difficulty of suture removal because they have less suture laxity for scissor insertion. The present invention therefore allows for more rapid suture removal with less patient discomfort and at a competitive or lower cost.

Devices and methods to deliver, retain and remove a separating device in an intussuscepted hollow organ

The present invention is an improved separating device for providing the malabsorptive component of a minimally invasive weight reduction system. This device may be a sleeve, liner, or tubular sheath that alters absorption of compositions through walls of hollow organs (stomach, intestines).
