Abstract: 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.

Abstract: In one aspect of the present disclosure, a tissue retraction system may include a first anchor, a second anchor, and an elongate coupling member extending between the first anchor and the second anchor. The system also may include a holder for receiving the first anchor, the second anchor, and the elongate coupling element. The holder may include a proximal portion and a distal portion. The distal portion may have a smaller width than the proximal portion such that the distal portion exerts a force on a proximal end of the first anchor during deployment of the first anchor from the holder. The force may move the first anchor into an open configuration for receiving tissue.

Abstract: The present disclosure relates to the field of tissue dissection. Specifically, the present disclosure relates to medical devices that lift and retract tissue during a dissection procedure to improve visualization of the target tissue and mitigate obstructions for dissection tools. In particular, the present disclosure relates to devices that transition from a constrained to an unconstrained bowed configuration to immobilize and retract the dissected portion of target tissue during a dissection procedure.

Abstract: The present disclosure relates generally to the field of medical devices and establishing access to body passageways. In particular, the present disclosure relates to devices, systems and methods to facilitate entry of an endoscopic accessory tool into and/or through patient-specific anatomies. For example, the devices, systems and methods of the present disclosure may transmit mechanical motion to the distal end of an endoscopic accessory tool to facilitate atraumatic access to tortuous or otherwise restricted anatomies.

Abstract: A system for controlling the flow of fluid through a medical device may include a medical device having a lumen that extends to a distal end of the medical device; a fluid source configured to supply fluid having a positive pressure to the lumen of the medical device; and a flow controller configured to apply a negative pressure to the fluid within the lumen, wherein the flow controller is triggered to apply the negative pressure upon a lowering of the positive pressure from the fluid source.

Abstract: 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.

Abstract: 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.
