摘要： Medical devices and methods of using medical devices are disclosed. An example tissue retraction device includes a first tissue engagement member coupled to an elastic member by a coupling assembly. The coupling assembly including a first coupler body having a first end region and a first compression member. Further, the first end region of the first coupler body is configured to extend into a portion of a lumen of the elastic member and the compression member is designed to compress the elastic member onto the first coupler body such that the elastic member is fixedly engaged with the coupler body.

摘要： Exemplary embodiments of the present disclosure relate to devices, systems, and methods for tissue resection in a body lumen of a patient, and may include an endoscope and a backstop delivery device extendable through the endoscope. The backstop delivery device may deliver a backstop to a location of selected tissue for resection. A backstop may include a covering being deployable in a patient. The covering may have one or more anchoring mechanisms disposed on an edge of the covering. A tissue resecting device may be extendable through the endoscope for resecting the selected tissue for resection. The covering may be deployable to an outer surface of the body lumen, such that the anchoring mechanism may secure the covering to the outer surface of the body lumen and the covering may expand to cover the selected tissue for resection.

摘要： Exemplary embodiments of the present disclosure relate to devices, systems, and methods for tissue resection in a body lumen of a patient, and may include a body extending along an axis and a distal cap positioned distally of the body and coupled to a shaft extending along the axis. The body and the distal cap may be movable relative to each other. An anchoring mechanism may be capable of engaging the body and the distal cap proximate a selected tissue for resection in the body lumen. A tissue capture device may be deployable from the tissue resection device such that a selected tissue for resection is securable by the tissue capture device. The tissue resection device may further include a tissue resecting device for resecting the selected tissue for resection.
