The present disclosure, in its various aspects, is directed to instrument accessory devices, implementation methods, and related delivery systems. Embodiments according to the present disclosure, including as described herein, may increase the effectiveness and efficiency of endoscopy procedures, such as ERCP. In one example, an embodiment includes an instrument accessory device with an expandable member, the device configured to receive an instrument through an instrument lumen, wherein the expandable member comprises an aperture on the inner surface and outer surface, and the outer surface is in fluid communication with the inner surface.

Devices, systems, and methods for an instrument accessory

In one example, a retrieval device may include a flexible loop; a net coupled to the loop, the net having an opening at least partially circumscribed by the loop; a sheath extending from a proximal end to a distal end; a cord extending through and/or around the net; and a connector assembly movable from a first configuration to a second configuration. In the first configuration, the flexible loop, the net, and the cord may be coupled to the sheath, and in the second configuration, the flexible loop, the net, and the cord may be detached from the sheath.

Medical retrieval systems, devices, and related methods

The present disclosure, in its various aspects, is directed to instrument accessory devices, implementation methods, and related delivery systems. Embodiments according to the present disclosure, including as described herein, may increase the effectiveness and efficiency of endoscopic procedures, such as Endoscopic Retrograde Cholangiopancreatography (ERCP). In one example, an embodiment includes an instrument accessory device with an expandable member, the device configured to receive an instrument through an instrument lumen, wherein the outer surface may comprise an expandable material. The device may comprise a constrainment element disposed about the outer surface of the expandable member, the constrainment element comprising a proximal end, a distal end, an inner surface, and an outer surface.

A medical device may comprise a distal tip having a viewing element, a lighting element, and at least one feature configured to removably couple the distal tip to a shaft. The medical device may also comprise a working channel coupled to the distal tip and defining a central lumen configured to receive a tool. A wall of the working channel may define at least one additional lumen. The working channel may be configured to be removably inserted into the shaft. The medical device may also comprise at least one of a wire, a cable, or a conduit passing through the at least one additional lumen.

Distal tips for medical devices

An esophageal atresia bridge device including a proximal anchor, a distal anchor, and a brace extending between the proximal anchor and the distal anchor. The brace permits the proximal anchor to move toward the distal anchor to apply a controlled tension that pulls the esophagus together and stretches the esophagus over time. A method of treating esophageal atresia may include inserting an elongate member of an esophageal atresia device into a mouth of a patient, the esophageal atresia device including a rotatable member including a threaded region, and rotating the rotatable member relative to the elongate member to longitudinally move the distal end of the elongate member relative to the rotatable member in order to apply a force to a proximal pouch of the patient's esophagus.

In one example, a retrieval device may include a flexible loop; a mesh coupled to the loop, the mesh having an opening at least partially circumscribed by the loop; a sheath extending from a proximal end to a distal end; a cord extending through and/or around the mesh; and a connector assembly movable from a first configuration to a second configuration. In the first configuration, the flexible loop, the mesh, and the cord may be coupled to the sheath, and in the second configuration, the flexible loop, the mesh, and the cord may be detached from the sheath.

The present disclosure relates generally to the field of medical devices for accessing body lumens. In particular, the present disclosure relates to medical devices, systems and methods for enlarging an opening of a body lumen. In an embodiment, a device may include a flexible elongate tube. A distal end of the tube may be configured to access an opening of a body lumen. A plurality of wire lumens may extend from the distal end of the tube toward a proximal end of the tube that are radially offset from and substantially parallel with a longitudinal axis. At least a portion of the plurality of wire lumens may be exposed to an outer surface of the tube along a distal portion. A plurality of wires may each extend along a respective wire lumen. A portion of each wire may extend externally to the wire lumens exposed to the outer surface.

Devices, systems, and methods for accessing a body lumen

A braided stent having an integral retrieval and/or repositioning loop includes a plurality of wires having first and second ends interbraided in a braided pattern to form a tubular stent having opposed atraumatic first and second open ends with each open end having a circumference; wherein said first and second wires ends are disposed at said second stent open end and said wires are looped at said second stent open end so that none of the first or second wires ends are exposed at the circumference of second stent open end; wherein at least of two of said wires are formed into a repositioning and/or retrieval loop having an elongated portion circumferentially disposed at said first opposed open end; and wherein said reposition and/or retrieval loop comprises two sections which run adjacent to each other prior to crossing to permit grabbing of both sections simultaneously by a practitioner.

Integrated stent repositioning and retrieval loop

A medical instrument may include a tube, a sheath provided around and coaxial with the tube, and an inflatable balloon at a distal end of the sheath. The balloon may receive a fluid from a lumen of the sheath, and may have a central opening along a longitudinal axis thereof, and into which the tube extends, a proximal portion, a middle portion adjacent to and distal of the proximal portion, and a distal portion adjacent to and proximal of the middle portion. When the balloon is inflated with the fluid, a maximum diameter of the middle portion may be less than a maximum diameter of the proximal portion, and less than a maximum diameter of the distal portion. The medical instrument may also include an extraction member provided at a distal end of the tube, distal to the balloon, and movable axially relative to the balloon.

Medical instrument having a balloon and an extraction member

The present disclosure relates generally to stents and methods for managing passage of material through a body lumen. In some embodiments, a medical stent may include a stent body defined by a hollow tubular elongate structure extending along a central axis, the stent body including a first portion and a second portion. The medical stent may further include a control region between the first and second portions, wherein in a first configuration the hollow tubular elongate structure of the control region is in a closed, twisted configuration, and wherein in a second configuration the hollow tubular elongate structure of the control region is in an open, expanded configuration.

The first and second wires ends are disposed at the second stent open end and the wires are looped at the second stent open end so that none of the first or second wires ends are exposed at the circumference of second stent open end. The at least of two of said wires are formed into a repositioning and/or retrieval loop having an elongated portion circumferentially disposed at the first opposed open end. The reposition and/or retrieval loop also includes two sections which run adjacent to each other prior to crossing to permit grabbing of both sections simultaneously by a practitioner.
