Abstract

Methods and devices for removing fasteners from tissue are described. One method is directed to surgically reversing a gastric restriction created using one or more fasteners. the fasteners can be disengaged from the gastric tissue and subsequently removed from the gastric tissue site. The method can utilize an endoscopically delivered fastener-extraction device to sever the fasteners by applyingenergy. In an exemplary device for removing fasteners, a substantially elongate body can include a fastener catch for selectively engaging tissue-attached fasteners. The device can also include a fastener-severing member and at least one fastener-removal element. The fastener-removal element can be adapted to be an energy delivery member that delivers an argon plasma to sever fasteners, while thefastener catch is adapted to shield tissue from direct energy contact.

Description

Technical field [0001] The present invention generally relates to devices and methods for fasteners, particularly devices and methods for removing fasteners that secure tissue under different patient treatment conditions. Background technique [0002] Severe obesity is a major health risk that can shorten life span and produce many other related diseases, including cardiovascular disease, hypertension, diabetes, and severe arthritis. Many surgical procedures can be performed to assist in the treatment of obesity. One example is gastric restriction surgery, in which one or more fasteners are inserted into gastric tissue, keeping the tissue in a folded configuration, thereby effectively reducing the effective capacity of the patient's stomach. [0003] In many cases it is desirable to remove the fastener. For example, it may be desirable to perform a temporary gastric restriction and then perform a longer-term surgery such as Roux-en-Y (Rox-en-Y) at the chosen time. It is often ne...
