NATURAL ORIFICE TRANSLUMINAL ENDOSCOPIC DEVICES FOR CLOSURE OF LUMINAL PERFORATIONS AND ASSOCIATED METHODS

摘要

Devices include at least two spaced apart flexible legs formed of a shape memory material, each leg having a respective free end configured to engage local tissue. The devices can also include at least one resilient member having opposing end portions, a respective end portion being attached to each leg at a location away from the free end. The resilient member is configured to take on a stretched configuration inside an endoscope during delivery. Alternatively or additionally, the devices include a cinch that is configured to snugly hold portions of both legs to force the legs closer together.

主权项

1. A natural orifice transluminal endoscope surgical method, comprising:
providing an endoscope with a device comprising a resilient crown that is fixedly attached to at least two flexible legs, each leg having a respective free end, each leg formed of shape memory material held in a straight linear shape in a longitudinal direction to a free end thereof in the endoscope with the resilient crown held in a stretched state; inserting the endoscope in a natural orifice of a patient to carry out a natural orifice transluminal surgery; then deploying the legs from the endoscope whereby the legs return to a pre-formed curvilinear configuration; attaching the legs to target tissue; and pulling the legs closer together to pull the target tissue closer together.
