摘要： Medical devices and methods of using medical devices are disclosed. An example tissue retraction device includes a first engagement member having a first end and a second end, a second engagement member having a first end and a second end, a first elastic member attached to the second end of the first engagement member, and a first alignment member having a first end, a second end and a lumen extending therethrough. Further, the tissue retraction device has a first length, the first alignment member has a second length, the first elastic member extends within the lumen of the first alignment member and the second length of the first alignment member is less than or equal to the first length of the tissue retraction device.

摘要： The present disclosure pertains to medical devices. More particularly, the present disclosure pertains to tissue clip devices and related systems and methods. In an embodiment, a tissue clip may include a grasper including jaws at a first end, and a spring portion at a second end, and a longitudinal axis extending along a length of the grasper from the first end to the second end, wherein the spring portion is configured to bias the jaws toward each other. A wedge may be slidably disposed between the jaws such that an apex of the wedge is oriented toward the spring portion. A filament may be coupled to the wedge at a first end of the filament and may extend through a channel of the spring portion of the grasper to a second end of the filament.

摘要： The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to a tissue traction device, e.g., for endoscopic tissue dissection. For example, a tissue traction device may include a first clip comprising opposable jaws. The device may include a traction band having a first end, a second end, a length therebetween and extending along a longitudinal axis. The band may have a first aperture at the first end. A second aperture may be at the second end of the band. A first jaw of the opposable jaws of the first clip may be disposed through the first aperture.

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.
