Abstract: Medical devices and methods of using medical devices are disclosed. An example tissue retraction delivery device includes a positioning assembly, the assembly including: a delivery catheter having a distal end region and a lumen extending therein, wherein the distal end region includes an engagement member orienting tip. The delivery device also includes an actuation catheter extending within at least a portion of the delivery catheter, the actuation catheter including a distal end region and a lumen extending therein. An actuation wire extends within the lumen of the actuation catheter, the actuation wire having a proximal end region and a distal end region. An end effector is coupled to the distal end region of the actuation wire, the end effector configured to capture an engagement member of a tissue retraction device, wherein manipulation of the actuation wire shifts the end effector from a first position to a second closed position.

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: A medical stent may include a tubular support structure including a plurality of struts defining a plurality of cells disposed between the plurality of struts. A polymeric coating may be disposed over the tubular support structure such that a first portion of the plurality of cells are closed by the polymeric coating in a first region of the tubular support structure and a second portion of the plurality of cells in a second region of the tubular support structure remain open to fluid flow and/or tissue ingrowth therethrough. The struts in the first region of the tubular support structure and the struts in the second region of the tubular support structure may be at least partially covered by the polymeric coating.

Abstract: An endoprosthesis includes an expandable tubular framework having a first end, a second end, and a lumen extending therethrough along a longitudinal axis. The expandable tubular framework includes a plurality of interconnected struts. The interconnected struts include a radially outward face which includes a plurality of anti-migration grooves defining anti-migration teeth formed therebetween. The anti-migration teeth are configured to engage tissue to resist migration of the endoprosthesis within a body lumen.
