Abstract: 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.

Abstract: The present disclosure relates generally to the field of medical devices. In particular, the present disclosure relates to devices and methods for controlled delivery of a stent, such as a self-expanding stent, and more particularly for controlling the full deployment of a stent in incremental steps from a sheath and for controlling the reconstrainment of a stent in incremental steps within a sheath.
