摘要： An implantable device configured to withstand forces imparted thereto by anatomical structure at a deployment site. The implantable device includes an outer portion and inner portion. The outer portion is positioned between the inner portion and the walls of the anatomical deployment site. The outer portion may enclose the inner portion. The outer portion may be a compliant balloon compressible in response to radially-inwardly directed anatomical forces exerted thereon. The inner portion may include one or more portions configured to retain the implantable device at the deployment site and to resist migration of the implantable device. The inner portion may be movable with respect to the outer portion. The inner portion may include more than one portions, such portions being movable with respect to each other. A shaft may extend through the device, such as to facilitate inflation of the outer portion and/or positioning of the inner portion.

摘要： Medical devices and methods for using medical devices are disclosed. Example fluid reservoirs and tube sets arranged and configured to couple to an endoscope for use in an endoscopic procedure are disclosed. An example fluid reservoir and tube set includes a fluid reservoir configured to contain a fluid, a fluid supply tube configured to be coupled to the endoscope and having a lumen extending therethrough, wherein the lumen is in fluid communication with the fluid reservoir and a first backflow prevention mechanism coupled to the fluid supply tube, the first backflow prevention mechanism configured to permit fluid to flow through the fluid supply line from the fluid reservoir to the endoscope and to prevent fluid from flowing back through the fluid supply tube from the endoscope to the fluid reservoir.

摘要： Medical devices for cinch and cutting one or more suture, and methods for making and using such devices are disclosed. An example medical device may include a coupler, a sleeve releasably coupled to the coupler, a cutter slidably disposed within the sleeve, and a suture cinching member movable into and out of the sleeve. A wire may extend through and be longitudinally movable within the coupler to move the suture cinching member and cutter.

摘要： 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.

摘要： Systems and methods for treating tissue may include one or more delivery devices, a grasping element, a first ring for anchoring to a wall of a gastrointestinal tract, and a second ring operably couplable to a radially inward surface of the first ring. Other embodiments include methods of treating tissues, including tubular tracts of tissue, comprising coupling a first ring to first tissue of a wall of a tissue tract, relocating a target tissue proximally to a position proximal to the first ring, coupling a second ring to the first ring, and cutting tissue proximal to the interface of the first and second rings.

摘要： A system for measuring a pressure in a vein includes a needle sized and shaped to be inserted through a working channel of an endoscope. The needle is extending longitudinally and including a channel extending longitudinally therethrough. The system also includes a pressure sensing device including a longitudinally extending body sized and shaped to be slidably inserted through the channel of the needle and a sensor mounted on a distal portion of the body and connected to a proximal portion of the pressure sensing device via a connection cable. The sensor is configured to detect information corresponding to a pressure of a flow of blood through a vein.

摘要： Embodiments of the disclosure include methods and systems for attaching an articulation section. In an embodiment, a medical instrument includes a first tubular member including a first end. The medical instrument also includes a second tubular member including a first end. The second tubular member includes a plurality of layers including an inner layer and a first layer including a fluorinated material. The inner layer includes a first section disposed under the first layer and a second section extending out from under the first layer. A portion of the first tubular member overlaps and is bonded to at least a portion of the second section of the inner layer of the second tubular member.

摘要： An endoprosthesis may include an expandable tubular framework expandable from a compressed state to an expanded state and include a plurality of strut rows, wherein adjacent strut rows define interstices spacing the adjacent strut rows apart, and a plurality of connectors extending across the interstices and interconnecting adjacent strut rows, at least some of the plurality of connectors defining a flexible hinge portion. The lengths of the interstices between adjacent strut rows may vary along the length of the expandable tubular framework. The plurality of connectors extend radially outward beyond an outer diameter of the plurality of strut rows in the expanded state. The plurality of connectors are configured to engage a wall of a body lumen in the expanded state to inhibit migration of the endoprosthesis subsequent implanting the endoprosthesis in the body lumen.

摘要： A stent of the present disclosure has a variable radial force along the longitudinal length of the stent. In particular, the radial force of the center is greater than the radial force of the ends of the stent. Without being bound by theory, the radial force is affected by the strut angle θ, the wall thickness t, the number of strut pairs, and combinations thereof. In one aspect of the present disclosure, the stent has a variable strut angle θ, a variable wall thickness t, and a variable number of strut pairs. By adjusting the strut angle θ, the wall thickness t, and the number of strut pairs of the serpentine bands, the stent will have a variable radial force without the need for additional processing steps.
