Abstract: Blunt tissue dissection using a sharp cutting instrument to make an initial cut in tissue and an inflatable device to further separate tissue layers on either side of the cut. The sharp cutting instrument may be advanced through the lumen of an elongate delivery member such as through a working channel of a medical scope. The inflatable device is inserted over the exterior of the elongate delivery member.

Abstract: Devices, systems, and methods of or for use with an elongate shaft of a medical scope. The device may be or may include a cap for the elongate shaft. The cap may include a proximal end, a distal end, a lumen extending between the proximal end and the distal end, and a protrusion located between the proximal end and the distal end. The proximal end of the cap may be configured to couple with the elongate shaft. The distal end of the cap may define a first diameter. The protrusion may define a second diameter that is smaller than the first diameter. The protrusion may be configured to engage tissue received in the lumen through the distal end.

Abstract: Exemplary embodiments of the present disclosure relate to devices, systems, and methods for tissue resection in a body lumen of a patient, and may include an elongate body having a cavity at a distal end and a tissue retractor extendable distally from the distal end of the elongate body. The tissue retractor may include an expansion mechanism. The expansion mechanism may include a plurality of arms each having a first end coupled around a distal cap and expandable radially outward from the distal cap such that an anchoring mechanism on a second end of the arms is engageable with selected tissue for resection of the body lumen. The tissue resection device may further include a tissue resecting device.

Abstract: Devices, systems, and methods for applying an elongate member to a shaft of an endoscope. The system may include a flexible elongate member and a tool for applying the elongate member to the shaft of the endoscope. The tool may include an elongate support and a plurality of connectors. The plurality of connectors may be longitudinally spaced apart along the elongate support(s). The plurality of connectors may be releasably coupled with the flexible elongate member at two or more locations along the flexible elongate member when the flexible elongate member is in a helical configuration.

Abstract: Devices, systems, and methods for coupling an elongate member with a shaft of an endoscope. The device for coupling an elongate member with a shaft of an endoscope may include a first contoured portion configured to mate with an outer surface of the shaft and a second contoured portion configured to couple with the elongate member. When the first contoured portion is mated with the outer surface of the shaft and the second contoured portion is coupled with the elongate member, the elongate member may be secured relative to the shaft. When secured relative to the shaft, the elongate member may be able to move longitudinally relative to the shaft.

Abstract: An assembly and/or system having a cutting device configured to cut tissue, and an inflatable device configured for insertion into the cut tissue to further separate the cut tissue. The inflatable device may be wedge shaped to separate the cut tissue upon insertion into the cut. The inflatable device is inflatable and otherwise adjustable to separate the tissue to a medically indicated extent. For instance, the inflatable device may be moved axially with respect to the cutting device; and/or may be sheathed or unsheathed to adjust an exposed inflated length thereof; and/or may include two or more separately inflatable elements. The inflatable device thus may be used to achieve blunt tissue dissection after an initial cut is made into the tissue with a sharper instrument.

Abstract: A fluid supply system for an endoscope includes a first container having an interior volume configured to contain a fluid, a second container having an interior volume configured to contain a fluid, and a coupling mechanism having a first portion and a second portion, and a lumen extending therebetween. The first portion of the coupling mechanism is configured to engage with the first container and the second portion is configured to engage with the second container. The first portion includes a first fluid port in fluid communication with the first container via the lumen, and the first container and the second container are in fluid communication via the lumen.
