Embodiment Construction

[0068] Referring to the drawings, wherein like reference numerals indicate like component parts throughout the several views. figure 1 with 2 An applicator 10 is depicted that is operable to transform an anastomotic ring device 12 from a generally cylindrical ( figure 1 ) to expand and actuate to a shape with a hollow rivet or ring feature ( figure 2 ), said shape is capable of forming an anastomotic junction at an anastomotic target site (eg, in an obese gastric bypass in a morbidly obese patient). It should be understood that the applicator 10 may be used in a variety of ways, including but not limited to laparoscopic or endoscopic. figure 1 with 2 Applicator 10 is shown with anastomotic ring 12 on deployment mechanism 18 . exist figure 1 The anastomotic ring 12 is shown in a cylindrically compressed position. exist figure 2 , the deployed configuration 18 of the applicator 10 has moved the anastomotic ring 12 to the hollow rivet-shaped actuated position. image 3 ...

Abstract

A surgical instrument includes a handle and an elongated shaft and is operable to remove an anastomotic ring device from a patient. The elongated shaft houses a plurality of ring engaging fingers. Each finger includes a sheath that houses a guide wire with a hook at its distal end. Each hook can be advanced beyond the distal end of the respective sheath to engage a flap on the anastomotic ring device. Subsequent proximal retraction of the hook secures the anastomotic ring device on the ring engaging fingers. With the anastomotic ring device secured to the ring engaging fingers, the fingers may be pulled together to collapse the anastomotic ring device from the actuated hollow rivet-shaped configuration to the unactuated cylindrical configuration. The surgical instrument can then receive the folded anastomotic ring device, thereby facilitating removal of the anastomotic ring device from the patient.

Description

technical field [0001] The present invention relates generally to surgery, and more particularly to an apparatus for performing surgical procedures on the digestive system. Background technique [0002] The proportion of the world's population suffering from morbid obesity is increasing. Severely obese people tend to increase the risk of heart disease, stroke, diabetes, lung disease and accidents. Because morbid obesity affects the life expectancy of patients, methods of treating morbid obesity have been the subject of serious research. [0003] One known method of treating morbid obesity involves the use of anastomotic rings. Devices for deploying anastomotic loops are known in the art. Devices of this nature are generally adapted to insert a compressed anastomotic ring into an anastomotic opening formed between the proximal tissue walls of the gastrointestinal tract. These applicators may utilize a ring expansion mechanism that includes an expansion element that is act...
